SYNOPSIS

milter-performance-check [option ...]

DESCRIPTION

milter-performance-check is a SMTP client that measures MTA performance. milter-test-server measures milter’s performance and miter-performance-check measures MTA + milter’s performance.

smtp-source bundled with Postfix is a similar tool. smtp-source has more features.

milter-performance-check is useful because it measures elapsed time of only SMTP sessions. smtp-source doesn’t provide the feature. You need to also use ’time’ command and measure smtp-source command runtime not elapsed time of SMTP sessions.

Normally, there isn’t big difference between elapsed time of SMTP sessions and tool runtime.

If you satisfy milter-performance-check’s features, it’s better that you use milter-performance-check. If you don’t, smtp-source is more better tool for you.

format that is also used by Postfix’s smtp_sasl_password_maps:

    SERVER1:PORT USER1:PASSWORD1
    SERVER2:PORT USER2:PASSWORD2
    ...

Here is an example configuration that "send-user" user and "secret" password account is used for "smtp.example.com" address and "submission port" (587 port) MTA:

    smtp.example.com:587 send-user:secret

The default is none.

--from=FROM Uses FROM as MAIL SMTP command.

The default from@example.com.

--force-from=FROM Uses FROM as MAIL SMTP command even if mail file includes "From:" header.

The default is none.

--recipient=RECIPIENT Uses RECIPIENT as RCPT SMTP command. If you want to use multiple recipients, use --recipient n-times.

--force-recipient=RECIPIENT Uses RECIPIENT as RCPT SMTP command even if mail file includes ’To:’ header. If you want to use multiple recipients, use --recipient n-times.

The default is none.

--n-mails=N Sends N mails. Some mails are sent concurrently. Maximum concurrency can be specified by --n-concurrent-connections

The default is 100.

--n-additional-lines=N Adds N lines into mail body.

The default is none. (Doesn’t add.)

--n-concurrent-connections=N Sends mails with N connections concurrently.

The default is 10.

--period=PERIOD Sends mails in PERIOD seconds/minutes/hours. Each mail is sent averagely. PERIOD is treated as seconds when its unit is omitted.

Example (100 mails are sent):

o --period=5 # sends mails at intervals of 0.05 seconds (5 / 100)
o --period=50s # sends mails at intervals of 0.5 seconds (50 / 100)
o --period=10m # sends mails at intervals of 6 seconds (60 * 10 / 100)
o --period=0.5h # sends mails at intervals of 18 seconds (60 * 60 * 0.5 / 100)

The default is none.

--interval=INTERVAL Sends mails at intervals of INTERVAL seconds/minutes/hours. INTERVAL is treated as seconds when its unit is omitted.

Example:

o --interval=5 # sends mails at intervals of 5 seconds
o --interval=0.5s # sends mails at intervals of 0.5 seconds
o --interval=10m # sends mails at intervals of 10 minutes
o --interval=0.5h # sends mails at intervals of 0.5 hours

The default is none.

--flood[=PERIOD] Sends flood of mails in PERIOD seconds/minutes/hours. If PERIOD is omitted, floods mails endlessly. PERIOD is treated as seconds when its unit is omitted.

The default is none.

--shuffle, --no-shuffle Shuffles target mails before sending.

The default is false. (don’t shuffle.)

seconds.

EXIT STATUS

Always 0.

EXAMPLE

In the following example, milter-performance-check connects a SMTP server running on localhost at 25 port and sends 100 mails. Each mail’s sender is from@example.com and recipients are webmaster@localhost and info@localhost.

    % milter-performance-check --recipient=webmaster@localhost --recipient=info@localhost

In the following example, milter-performance-check connects a SMTP server running on 192.168.1.102 at 25 port and sends files under /tmp/test-mails/ directory. The files should be RFC 2822 format. The mails are sent to user@localhost at intervals of 3 seconds (60 * 10 / 100). Each mail is sent only 1 time because of --n-mails=1 option.

    % milter-performance-check --n-mails=1 --smtp-server=192.168.1.102 --force-recipient=user@localhost --period=5m /tmp/test-mails/
