milter-performance-check — MTA performance check program

NAME

milter-performance-check - MTA performance check program

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.

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/
