A
Okay,
last
week,
I
was
working
on
working
on
the
performance
equation
into
new
Jenkins.
Basically,
it
happened
on
the
subsided
to
be
specific.
I
am
added
tours
I'm,
putting
in
the
chat
window
to
run
CB
test
locally,
based
on
the
the
work
by
by
Redick,
so
the
so
we
are
able
to
run
CBT
using
a
single
command
line
and
I.
Think
in
my
my
next
step
need
to
to
write
another
tool
to
compare
the
monitor
the
test
without
with
a
baseline
and.
A
When
he
gave
that
I'll
read
out
to
to
vote
our
vote
up
or
boot
down
to
a
sig,
a
certain
didn't
change
and
at
all
and
the
I
said
affirm,
it
I
will
also
to
do
some
performance
from
a
test
regarding
to
the
theta
rised
Rock
DB,
to
figure
out
what
route
we
will
be
going.
That's
me
I
can
make
by
the
way
I
was
I'm.
Still
reviewing
your
your
change.
For
me,.
A
That's
a
week,
I
was
working
on
the
signe
face
to
perform
the
test,
so
it's
a
basically
work.
It's
fine,
so
the
end
result
is
that
we
can
run
a
speed
test
with
a
single
command
line
and
then
my
next
step
is
e
to
to
to
first
things,
to
integrate
it
into
the
Jenkins
and
and
another
thing
to
write
it
another
tool
to
compare
the
test
with
other
ways
that
baseline
Purdue
by
the
mass
branch.
A
B
In
the
blue,
stop
and
the
GT
be
will
will
hum
when
I
run,
where
we
are
run,
run
the
process
in
the
gdb.
Finally,
I
found
out
it
because
the
heap
profile
I
couldn't
use
the
hip
prepare
in
this
Easter
framework.
I
have
to
disable
to
keep
profile.
Otherwise,
gdb
cannot
another
one.
So
after
load
the
chromosome
ski
symbol
and
it
printed
using
the
library,
the
DB
dot
s
or
without
the
one.
It
will
stack
there
and
you
couldn't
write
any
commander.
You
couldn't
so
I
took
three
days
to
found
out
that
judges.
A
B
Yeah
see,
profit
are
using
TC
Malacca,
and
so
maybe
there's
some
confliction,
so
GTV
bill
hung
there
and
I
couldn't
think
back
on
it.
But
my
target
link
at
the
library
TV
the
cave,
elaborate
link
to
the
daily
stock
and
the
skipper
profile
link
to
the
cave
o'clock
angle
to
the
kV.
Then
so
the
gdb
block
there
I
couldn't
debugger
continue
to
debug.
Finally,
I
disabled
the
disable
affair,
disable
the
TC
Malik
in
the
in
the
blue.
Stop
the
gdb
can
continue
on.
You
can
run
the
rank
mountain
executive
recommend
in
gdb.
A
A
A
D
A
But
I
think
and
it's
a
disputed
thought
but
underhand
it
should
have
a
look.
Would
you
look
in
store
so.
D
A
A
C
F
We
do
we
put
the
data
on
the
wire
and
treat
into
and
read
it
back
in
objector
to
a
field
called
extra
info.
However,
this
this
field
is
our
private
one
and
uses
it.
So
it
seems
strange,
I,
went
I,
gripped
the
kernel
source
and
cannot
find
any
user
even
dirt,
so
made
a
PR.
Detecting
made
appear
tropic
this
stuff
entirely
waiting
for
waiting
for
reviews
there.
The
last
PR
is
the
initial
verse
is
the
part
one
of
that
subclass
support
for
crimson.
F
G
I
was
thinking
about
how
to
do
it
better.
What
I
did
was
I
guess
felt.
Yesterday,
I
sent
a
question
a
detailed
question
to
the
sISTAR
mailing
list
after
I
try
to
talk
to
internally
with
people
between
simply
sentences
and
a
question
I
ve,
given
from
sister
of
Silla.
He
answered,
if
suggest,
an
even
bigger
change.
He
suggests
dropping
templates,
making
the
whole
socket
implementation
non
templated.

Last
two
weeks
last
week,
us
and
at
the
flash
memories
other
part,
but
make
those
good.
The
main
takeaway
from
that
meeting
is
that
you
hear
a
lot
about
zone
name.
Space
SSDs
probably
foresee
store
it's
gonna
matter.
D
It's
just
necessary.
You
have
to
write
to
sequentially,
it's
not
the
end
of
the
world,
but
it
looks
like
that's
the
way
the
industry
is
going,
particularly
for
quad
level
cell
memory,
so
that'll
be
important
when
we
start
designing
the
display,
outs
and
stuff
for
every
store.
What
I
want
to
do
this
week
is
I'm
getting
started
on
the
opening
log
based
recovery
in
tactical
crimson.
D
D
Welcome
I
came
rubber
what
his
name
was,
but
yeah
I
spent
some
time
talking
to
him.
The
main
takeaway
from
that
technology
seems
to
be
offloading
the
CPU
usage
from
the
host,
because
you
don't
have
to
run
a
rocks
to
be
instance
because
rocks
to
be
is
particularly
expensive
in
CV
usage,
but
the
only
vendor
I
talked
to
that
was
implementing.
D
One
of
these
is
this
guy
from
Samsung,
so
I
don't
know
for
what
I
can
tell,
maybe
not
so
much,
and
even
if
it,
and
here
here's
the
kicker
they're
working
on
putting
it
under
or
creating
an
outpost
or
implementation
based
on
it
for
stuff,
you
know
for
clásicos
d,
but
they
haven't
implemented
transactions
yet
and
for
those
of
us
who
are
around
for
the
kinetic
effort
a
few
years
ago,
that
was
what
killed
it.
The
problem
is
that
it
these
drives,
cannot
have
transactions
built-in
and
stuff
needs
transactions.
D
So
if
you
have
a
key
value
store
with
no
multi
key
transactions,
you
have
to
implement
logging
using
keys,
which
means
you're,
double
writing
using
keys
and
then
writing
to
the
actual
keys
you
want
right
to
which
isn't
good
though
I
don't
know.
My
instinct
is
my
instinct.
Is
that
that's
a
very
complicated
interface
standardized
in
a
way
that
will
be
efficient
for
a
lot
of
uses,
though
it's
probably
not
gonna
have
legs
but
I'm
happy
to
be
wrong.
D
We'll
see
those
own
namespace
SSD,
though
there
were
at
least
four
vendors,
hawking
versions
of
that
it's
super
popular
though
that
was
for
sure
the
key
value
thing
we'll
keep
an
eye
out,
maybe
maybe
it
does
catch
on
its
ass
Nia
standard
now.
So
it's
absolutely
crazy,
like
there
is
a
standardized
interface
for
it.
Now.
This.
D
D
There's
even
an
implementation
in
the
Ceph
code
base,
for
it
I
think
that's
the
KP
store
thing
somewhere
it
down
in
there
it
just.
It
was
never
anything
like
something.
You'd
want
to
use.
The
only
way
that
version
made
sense
is
if
you
actually
ran
the
OSD
on
the
drive,
which
would
be
cool.
That
would
be
an
interesting
option,
but
having
both
the
extra
expense
of
the
more
complicated
drive
and
a
full
set,
those
running
doesn't
make
sense
from
a
TCO
point
of
view.
D
So,
but
these
aren't
that
these
are
more
like
they're
running
the
key
value
store
on
this
stuff
in
the
FTL
layer
microcontroller.
So
it
doesn't
increase
platform
cost
as
much
as
you
think.
It's
just
that
the
interface
seems
very
restrictive
and
it
seems
like
if
you
have
to
do
anything
that
forces
you
to
overlay
something
more
complicated.
On
top
of
the
keys
you
give
back
all
the
performance
gains.
The
key
values
for
interface
gave
you
in
the
first
place.
G
C
D
G
It
this
might
be
a
question
or
teen
doctor
if
you
saw,
but
there
will
be
an
in,
they
are
preparing
of
the
questions
for
being
diffusers
questionnaire
for
this
year,
other
there
is
a
questionnaire
that
is
they
and
to
all
our
customers.
Also
for
suffuses
asking
is
specific
questions
regarding
sizes
usage,
types
of
replicas
etc,
and
this
is
the
chance
to
add,
also
or
request
to
add
questions
understand.
What
are
you
put?
Our
users
need
may
be
changing
if
we
have
things
that
we
are
already
guessing
it.
G
E
Mm-Hmm
hi
I'm
still
working
on
the
unit
test,
and
this
is
a
current
example
of
a
test
and
the
first
part
we
can
define
which
step
is
failed
and
the
second
part
is
to
define
how
how
test
runs
and
the
wait
for
the
result,
and
the
third
part
is
to
check
that
all
the
three
points
are
triggered
correctly
and
I'm,
still
working
on
to
add
more
test
cases
and
and
test
features
and
continue
to
do
to
fix
this
in
in
the
messenger.
So
that's
all
this
week,
you're.
