A
Good
day
and
welcome
to
SharePoint
performance
mini
series
today
we
know
we
were
dealing
with
season
1
episode
5,
which
is
the
CDN
summary
and
also
optimizing
connectivity,
so
network
connectivity
to
UCD
ends
as
for
the
other
seasons
or
the
other
episode
should
I,
say
I
suggest
you
watch
them.
If
you
want
to
know
more
details
on
CD
ends,
this
one's
really
going
to
focus
on
a
very
brief
summary
and
then
also
just
courage
into
what
you
should
be
looking
for
from
a
networking
perspective,
you
don't
need
to
be
networking
personally
watching
this.
A
In
fact,
this
is
targeted
at
SharePoint
team
who
now
needs
obviously
code
in
the
network,
no
infrastructure
team
to
actually
get
and
understand
to
make
sure
the
settings
are
correct.
So,
as
we
go
through
the
agenda,
you'll
see
that
it's
an
overview
and
summary
promisingly,
neck
tivity
and
then
as
well
as
a
verifying.
You
know,
I
hate
it.
Yes,
it's
using
CD
ends
or
it's
not
I
mean
that
as
part
of
that
I'll
summarize
in
the
end
as
well.
A
A
user
also
with
the
edge
node
noted
there,
and
in
this
particular
case
the
green
lines
are
the
Microsoft
Network
as
it
connects
into
the
data
center
and
in
this
particular
case
in
the
data
center,
is
in
North
America
and
looks
to
be
around
about
Chicago
now
without
CD
ends.
The
following
would
be
your
traffic
and
I'll
go
through
very
quickly.
I
make
a
call
to
a
page
from
that
page.
I
have
let's
say
ten
images,
or
even
one
image,
whatever
it
is,
or
a
javascript
file
or
a
CSS
file.
A
I
want
to
make
the
call
it
actually
traverses
across
the
entire
network
until
it
comes
back
to
the
user
in
the
UK.
Obviously,
from
that
perspective,
the
latency
or
there
the
performance
through
that
would
be
pretty
pretty
little
arrogantly
slow
and
the
same
would
happen
for
United
States
use.
As
you
can
see
there,
what
you're
seeing
is
that
it's
actually
going
down
to
again
across
the
neighborhood.
Yes,
it
may
be
a
little
bit
faster
to
the
u.s.
user
in
this
particular
case,
because
I've
always
see
the
shorter
halt,
but
not
using
CDNs.
A
A
So
here
we
come
along
with
CD
ends
and
a
zosky
in
the
UK
the
same
file
access,
even
though
you've
made
a
call
to
the
webpage,
which
technically
is
coming
from
the
new
SharePoint
data
center.
It
actually
is
actually
reading,
though
it's
any
files
in
CDN
at
the
Lotus
point-
and
in
this
case
the
CDN
may
be
said,
you
can
here
the
CDN
is
closed.
So
that's
that
location.
They
would
then
experience,
obviously
a
far
greater
throughput
than
if
it
was
coming
all
the
way
across
the
line.
A
It's
also
the
fact
that
it's
HTTP
2
and
it's
and
therefore
also
you
have
more
threads
from
the
browser
and
therefore
we
see
needs
for
modern
browsers,
like
Age
chromium,
edge
or
even
chrome
itself,
and
the
same
would
happen
for
the
u.s.
user,
and
you
would
see
that
that
would
then
pull
from
the
location
closest
to
the
user.
So
therefore
centralizing
your
traffic
through
a
central
proxy
I'll
go
into
a
little
bit.
More
would
also
not
make
sense
in
this
particular
scenario
because
of
all
the
users
here.
A
I
did
that
they
wouldn't
be
using
this
Microsoft
network
and
you'll.
Note
the
wrong
notes
here
about
pre-existing
connection.
What
that
means.
Is
we
reuse
that
connection?
So
you
don't
have
to
have
a
three-way
hand
shoulder
an
actus
in
and
an
ACK
to
actually
then
go
and
main
obviously
seen
the
traffic
that
connection
is
kept
alive
and
therefore
it
actually
utilizes
the
back.
You
have
a
better
throughput,
just
a
quick
slide
on
CD
ends
here,
I'm
not
going
to
go
through
each
point,
but
the
main
thing
here
is
CD
ends
or
content
delivery
networks.
A
You
have
the
two
main
ones:
we've
talked
about
Cera's,
public
and
private.
The
way
public
is
not
that
it
it's
not
associated
or
tenant.
It
is
always
associated
to
your
tenant,
but
it
is
not
locked
down
to
your
tenant,
meaning
I,
don't
need
to
be
authenticated.
I
do
have
to
be
coming
from
a
SharePoint
location
if
I
happen
to
have
the
URL.
Someone
would
have
to
give
me
that
URL,
whereas
in
private,
is
a
60
minute
life
span.
It
is
cookie
based
on
the
first
user
accessed
and
it
changes.
So
what?
A
If
you
do,
don't
try
you
reuse,
private
and
try
and
think
even
hard
coded
privates.
It
will
change
every
60
minutes
and
you
will
experience
file
not
found
errors,
because
that
location
is
no
longer
available
off
to
that
point
and
again
for
someone
to
actually
get
to
that,
you
physically
have
to
go
and
copy
that
long,
URL,
try
and
share
it
out
then
try
and
actually
get
there
and
it's
obviously
a
far
more
secure
configuration
right.
So,
let's
just
jump
straight
in
and
that's
what
the
session
is
really
about.
A
A
You'll
notice,
we
provide
the
IPS
and
we
provide
the
URLs.
Please
use
the
URLs
of
the
IPS
to
are
subject
to
change.
Whilst
we
do
have
a
service,
probably
public.
These
changes
publish
these
changes
too.
The
problem
is
that
it's
a
pretty
complicated
process
when
you
can
go
and
update
the
EIP
instead
divided
bottle
or
time.
So
we
provide
you
with
the
URLs
you'll
notice.
They
got
wildcards
and
you'll
notice.
They
specific
to
Microsoft
you'll,
also
see
in
some
of
these
you'll
see
ekam
I
in
particular.
I
know.
A
This
is
quite
a
small
view
on
that
you've
seen.
But
if
you
go
to
that
links,
you'll
have
a
detailed
list
of
needs,
and
these
your
networking
team
should
follow
and
actually
make
sure
that
you
bypass
the
proxy
now
from
a
perspective.
It
could
be
an
online
proxy
service.
It
could
be
an
internal
party
that
you
have
and
typically
issues
and
common
scenarios
we
see
am.
A
This-
is
that
a
networking
team
will
in
fact
interrogate
the
traffic
going
to
office
365,
so
we're
taking
the
fact
that
you
have
a
secure
connection
already
to
office
365
our
HTTPS
and
at
2048
encryption
and
now
there's
only
there's
a
level
of
the
encryption
encryption
in
a
way,
because
you
know
that's
sort
of
the
old
networking
standards
hey
we
need
to.
We
need
to
they'll
get
all
traffic
that
goes
through
our
network.
Now
it's
office,
365
ready,
got
a
secure
connection.
A
We
recommend
not
interrogating
the
traffic
making
sure
you
bypass
your
proxy
servers
to
get
to
SharePoint,
Online
and
office
365,
because
all
that
is
doing
is
causing
increased
latency
and
in
fact
there
are
some
scenarios
where
you
would
have
shakespeareans
issues,
because
it's
actually
impacting
the
overall
payload
page
load.
It's
impacting
your
dynamic
documents,
opening
documents
all
of
these
factors
simply
because
of
not
following
these
online.
This
online
guidance.
A
It
is
a
well
published
set
of
guidance,
you'll
notice,
the
second
link
on
them
on
the
left
as
well
talks
about
the
tuning
site
and
that's
really
for
the
overall
over
365
guidance.
You'll
see
it
talks
about
exchange
talks
about
Skype.
It
talks
about
sharepoint,
onedrive
common
settings.
You'll
see
often
we
refer
to
CDN
and
Akamai.
Akamai
is
currently
the
hosting
provider
that
we
have
and
we
utilize
around
the
world
you'll
notice
that
it's
private
CDN
dot
shape
on
online.com
you'll
notice
that
this
public
CDN
online,
dr.
A
A
Now.
What
you'll
see
next
is
we
go
on?
Is
I'm
gonna
actually
take
you
through
and
show
you
how
to
actually
verify
you
then
using
the
fact
that
you
are
using
CD
ends.
So
let
me
hop
over
and
what
I've
got
share
is
a
simple
one
of
our
Microsoft
websites
and
in
there
I'm
gonna
hit
the
f12
feature
to
get
through
to
the
developer
tools
and
I've
already
pre-loaded
this,
but
effectively,
you
don't
need
to
be
a
developer
to
PDF
12
in
dude.
A
You
simply
refresh
the
page,
equal,
the
in
load
and
what
you're
seeing
is
all
the
calls
that
are
made
to
generate
this
page
now,
some
of
the
key
things
and
I'll
zoom
in
a
little
bit
so
that
you
can
actually
see
it
and
I'll
zoom
into
this
one
very
quickly
and
what
you're
gonna
see
over
here
is
obviously
there's
the
JavaScript
files
and
I
want
to
just
try
and
show
you
that
URL
in
a
bit
more
detail.
So
as
we
zoom
into
it,
there.
A
And
what
you'll
notice,
as
we
look
at,
is
that
the
first
one
shows
is
the
Akamai
HD
dotnet
you're
on
that
as
well
as
I
said
before
is
one
of
the
URL.
So
you
know
that
that's
our
SharePoint
service
ones
that
we're
actually,
we
have
Microsoft,
have
said
not
using
and
as
I've
go,
but
the
next
one.
What
you'll
see
there
is
that
it's
actually
showing
you
a
an
additional
one
which
is
going
to
be
the
public
CD
end
or
chiffon
online.com
I'm,
not
showing
that
for
that
particular
asset.
A
We
are
actually
looking
at
and
using
the
public
CDN.
For
that
purpose,
it's
a
very
quick
check,
but
the
key
thing
that
you
need
to
do
there
is
make
sure
you
go
through
all
of
your
JavaScript,
all
of
your
CSS
or
your
images
on
the
page
and
make
sure
they
are
fully
from
CDN
when
they
supposed
to
be
now
the
are
scenarios,
as
I
mentioned
in
the
other
episodes
where
there
won't
be
possible.
A
So,
for
example,
if
you've
directly
reference
a
file
directly
from
your
client-side
code
or
your
script,
we
aren't
going
to
be
able
to
rewrite
that
URL
with
CDN.
It
is
something
not
possible
today.
If
you
look
at
episode
forever,
I
show
you
how
to
actually
do
certain
amount
of
that
as
long
as
you're
using
public
CDN,
you
can
actually
use
an
almost
hard-coded,
your
l.
We
don't
want
you
to
hard-coded,
so
we
provided
you
with
a
property
that
you
can
actually
use
for
that
right.
A
So
just
jumping
back
and
going
over
the
remaining
portions
of
this
is
talked
about
and
just
do
a
summary
of
your
network
and
how
to
connect
the
CDN
so
first
of
all,
35
with
your
firewall
on
the
networking
team.
Obviously
they
need
be
deeply
involved
in
this
process
and
they
didn't
follow
that
by
parts
proxy
list
to
ensure
that
number
one
you
have
good
connectivity
through
to
office
365
their
wall
up
also
that
the
Akamai
locations
are.
A
We
include
those
in
our
list,
but
a
lot
of
people
exclude
them
when
they're
actually
trying
to
set
up
and
actually
bypass
proxy.
We
provide
you
the
exact
details
needed
for
you
to
actually
know
that
those
on
Microsoft's
specific
locations
required
for
best
connectivity
to
our
services
and
then
checking
the
use
and
performance.
Obviously
something
that
you've
got
to
consider
is
that
these
CD
ends
make
sure.
A
First
of
all,
the
file
will
probably
really
from
Zn,
but
if
they're
taking
stance
of
amount
of
time
to
render
I
mean
over
half
a
second
to
render
a
file,
it's
fully
pretty
lengthy,
particularly
if
you
have
ten
or
twelve
or
fifteen
files,
something
in
some
cases
on
the
page.
I
would
then
look
at
your
neighbor
look
and
see
what
is
causing
it.
We
typically
use
here
about
a
hundred
to
five
hundred
milliseconds
for
seeing
you
in
rendering
time,
but
it
does
depend
on
your
connectivity,
traffic
and
so
on.
A
So
just
make
sure
you
know
it
is
big
differences.
Downloading
check
from
an
outside
location
see
that
it's
not
your
own
network
causing
the
bottleneck,
because
that
could
definitely
have
the
performance
for
you.
Thank
you
once
again
for
watching
season.
1
episode,
5
the
loss
in
this
particular
season,
particularly
focus
on
CD
ends
some
helpful
links.
As
usual,
there
in
the
end
for
you
to
actually
go
through
and
look
at,
and
these
are
helpful
links
when
you
get
to
the
information
in
your
need.
Thanks
once
again
for
watching
goodbye.
