TCP

 

Segmentation

 

Offload

 

(TSO)

 

offloads

 

the

 

splitting

 

of

 

outgoing

 

TCP

 

data

 

into

 

packets

 

to

 

the

 

adapter.

 

TSO

 

benefits

 

applications

 

using

 

TCP.

 

Applications

 

using

 

protocols

 

other

 

than

 

TCP

 

will

 

not

 

be

 

affected

 

by

 

TSO.

Enabling

 

TSO

 

will

 

reduce

 

CPU

 

utilization

 

on

 

the

 

transmit

 

side

 

of

 

a

 

TCP

 

connection

 

and

 

improve

 

peak

 

throughput,

 

if

 

the

 

CPU

 

is

 

fully

 

utilized.

 

Since

 

TSO

 

has

 

no

 

effect

 

on

 

latency,

 

it

 

can

 

be

 

enabled

 

at

 

all

 

times.

 

The

 

driver

 

has

 

TSO

 

enabled

 

by

 

default.

 

Therefore,

 

there

 

is

 

no

 

opportunity

 

to

 

improve

 

performance

 

from

 

the

 

default.

TSO

 

is

 

controlled

 

using

 

ethtool:

#

 

/sbin/ethtool

 

–K

 

<ethX>

 

tso

 

<on|off>

Verification

 

of

 

the

 

TSO

 

settings

 

may

 

be

 

performed

 

by

 

running

 

ethtool

 

with

 

the

 

–k

 

option.

TCP

 

and

 

IP

 

checksum

 

offloads

 

must

 

be

 

enabled

 

for

 

TSO

 

to

 

work.

NOTE:

 

Solarflare

 

recommend

 

that

 

you

 

do

 

not

 

disable

 

this

 

setting.

TCP

 

Large

 

Receive

 

Offload

 

(LRO)

TCP

 

Large

 

Receive

 

Offload

 

(LRO)

 

is

 

a

 

feature

 

whereby

 

the

 

adapter

 

coalesces

 

multiple

 

packets

 

received

 

on

 

a

 

TCP

 

connection

 

into

 

a

 

single

 

larger

 

packet

 

before

 

passing

 

this

 

onto

 

the

 

network

 

stack

 

for

 

receive

 

processing.

 

This

 

reduces

 

CPU

 

utilization

 

and

 

improves

 

peak

 

throughput

 

when

 

the

 

CPU

 

is

 

fully

 

utilized.

 

The

 

effectiveness

 

of

 

LRO

 

is

 

bounded

 

by

 

the

 

interrupt

 

moderation

 

delay,

 

and

 

is

 

limited

 

if

 

interrupt

 

moderation

 

is

 

disabled

 

(see

 

Interrupt

 

Moderation

 

(Interrupt

 

Coalescing)

 

on

 

page

 

105

).

 

Enabling

 

LRO

 

does

 

not

 

itself

 

negatively

 

impact

 

latency.

NOTE:

 

The

 

Solarflare

 

network

 

adapter

 

driver

 

enables

 

LRO

 

by

 

default.

 

By

 

its

 

design,

 

LRO

 

is

 

of

 

greater

 

benefit

 

when

 

working

 

with

 

smaller

 

packets.

 

For

 

Solarflare

 

adapter,

 

LRO

 

will

 

become

 

disabled

 

if

 

the

 

MTU

 

is

 

set

 

larger

 

than

 

3979.

 

When

 

the

 

MTU

 

is

 

set

 

larger

 

than

 

3978,

 

LRO

 

cannot

 

be

 

enabled

 

and

 

will

 

be

 

reported

 

as

 

‘fixed

 

disabled’

 

by

 

ethtool.

 

NOTE:

 

LRO

 

should

 

NOT

 

be

 

enabled

 

when

 

using

 

the

 

host

 

to

 

forward

 

packets

 

from

 

one

 

interface

 

to

 

another.

 

For

 

example,

 

if

 

the

 

host

 

is

 

performing

 

IP

 

routing.
