クラウドでのネットワーク レイテンシの測定より
クラウド アーキテクトによく寄せられる質問の一つに、「2 つのエンドポイント間でリクエストとレスポンスをどの程度まで迅速に交換できるのですか？」というのがあります。ネットワークのラウンドトリップ レイテンシを測定するツールには ping、iperf、netperf などがありますが、すべてが同じように実装、構成されるわけではないため、ツールによって結果が異なる場合があります。ほとんどの場合、この質問に対する代表的な回答が得られるツールは、netperf であると考えられます。
netperfコマンドは、単一リージョン内の単一のゾーンにある 2 台のマシン間でゾーン内レイテンシ ベンチマークを実行します。このようなゾーン内ベンチマークを使用することで、緊密に連携するマシン間の非常に低いレイテンシをマイクロ秒単位で示すことができます。
ということで、詳しい内容は この情報を読むということで、netperf を macOS と Linux(Redhat と Debian系)へインストールして実行してみてみます。

shirok@macbook~ % netperf -h
Usage: netperf [global options] -- [test options]
Global options:
-a send,recv Set the local send,recv buffer alignment
-A send,recv Set the remote send,recv buffer alignment
-B brandstr Specify a string to be emitted with brief output
-c [cpu_rate] Report local CPU usage
-C [cpu_rate] Report remote CPU usage
-d Increase debugging output
-D time,[units] * Display interim results at least every time interval
using units as the initial guess for units per second
A negative value for time will make heavy use of the
system's timestamping functionality
-f G|M|K|g|m|k Set the output units
-F lfill[,rfill]* Pre-fill buffers with data from specified file
-h Display this text
-H name|ip,fam * Specify the target machine and/or local ip and family
-i max,min Specify the max and min number of iterations (15,1)
-I lvl[,intvl] Specify confidence level (95 or 99) (99)
and confidence interval in percentage (10)
-j Keep additional timing statistics
-l testlen Specify test duration (>0 secs) (<0 bytes|trans)
-L name|ip,fam * Specify the local ip|name and address family
-o send,recv Set the local send,recv buffer offsets
-O send,recv Set the remote send,recv buffer offset
-n numcpu Set the number of processors for CPU util
-N Establish no control connection, do 'send' side only
-p port,lport* Specify netserver port number and/or local port
-P 0|1 Don't/Do display test headers
-r Allow confidence to be hit on result only
-s seconds Wait seconds between test setup and test start
-S Set SO_KEEPALIVE on the data connection
-t testname Specify test to perform
-T lcpu,rcpu Request netperf/netserver be bound to local/remote cpu
-v verbosity Specify the verbosity level
-W send,recv Set the number of send,recv buffers
-v level Set the verbosity level (default 1, min 0)
-V Display the netperf version and exit
-y local,remote Set the socket priority
-Y local,remote Set the IP_TOS. Use hexadecimal.
-Z passphrase Set and pass to netserver a passphrase
For those options taking two parms, at least one must be specified;
specifying one value without a comma will set both parms to that
value, specifying a value with a leading comma will set just the second
parm, a value with a trailing comma will set just the first. To set
each parm to unique values, specify both and separate them with a
comma.
* For these options taking two parms, specifying one value with no comma
will only set the first parms and will leave the second at the default
value. To set the second value it must be preceded with a comma or be a
comma-separated pair. This is to retain previous netperf behaviour.

● netperfインストール確認
1) netperfコマンド確認
shirok@gcp-instance-ubuntu:~$ which netperf
/usr/local/bin/netperf
shirok@gcp-instance-ubuntu:~$ netperf -h
Usage: netperf [global options] -- [test options]
Global options:
-a send,recv Set the local send,recv buffer alignment
-A send,recv Set the remote send,recv buffer alignment
-B brandstr Specify a string to be emitted with brief output
-c [cpu_rate] Report local CPU usage
-C [cpu_rate] Report remote CPU usage
-d Increase debugging output
-D time,[units] * Display interim results at least every time interval
using units as the initial guess for units per second
A negative value for time will make heavy use of the
system's timestamping functionality
-f G|M|K|g|m|k Set the output units
-F lfill[,rfill]* Pre-fill buffers with data from specified file
-h Display this text
-H name|ip,fam * Specify the target machine and/or local ip and family
-i max,min Specify the max and min number of iterations (15,1)
-I lvl[,intvl] Specify confidence level (95 or 99) (99)
and confidence interval in percentage (10)
-j Keep additional timing statistics
-l testlen Specify test duration (>0 secs) (<0 bytes|trans)
-L name|ip,fam * Specify the local ip|name and address family
-o send,recv Set the local send,recv buffer offsets
-O send,recv Set the remote send,recv buffer offset
-n numcpu Set the number of processors for CPU util
-N Establish no control connection, do 'send' side only
-p port,lport* Specify netserver port number and/or local port
-P 0|1 Don't/Do display test headers
-r Allow confidence to be hit on result only
-s seconds Wait seconds between test setup and test start
-S Set SO_KEEPALIVE on the data connection
-t testname Specify test to perform
-T lcpu,rcpu Request netperf/netserver be bound to local/remote cpu
-v verbosity Specify the verbosity level
-W send,recv Set the number of send,recv buffers
-v level Set the verbosity level (default 1, min 0)
-V Display the netperf version and exit
-y local,remote Set the socket priority
-Y local,remote Set the IP_TOS. Use hexadecimal.
-Z passphrase Set and pass to netserver a passphrase
For those options taking two parms, at least one must be specified;
specifying one value without a comma will set both parms to that
value, specifying a value with a leading comma will set just the second
parm, a value with a trailing comma will set just the first. To set
each parm to unique values, specify both and separate them with a
comma.
* For these options taking two parms, specifying one value with no comma
will only set the first parms and will leave the second at the default
value. To set the second value it must be preceded with a comma or be a
comma-separated pair. This is to retain previous netperf behaviour.
2) netserver確認
shirok@gcp-instance-ubuntu:~$ which netserver
/usr/local/bin/netserver
shirok@gcp-instance-ubuntu:~$ netserver -h
Usage: netserver [options]
Options:
-h Display this text
-D Do not daemonize
-d Increase debugging output
-f Do not spawn chilren for each test, run serially
-L name,family Use name to pick listen address and family for family
-N No debugging output, even if netperf asks
-p portnum Listen for connect requests on portnum.
-4 Do IPv4
-6 Do IPv6
-v verbosity Specify the verbosity level
-V Display version information and exit
-Z passphrase Expect passphrase as the first thing received
