+# BATCH STRESS TEST FOR IMAP ----------------------
+# http://imgs.xkcd.com/comics/science.jpg
+#
+# Run imaptest against a LEAP IMAP server
+# for a fixed period of time, and collect output.
+#
+# Author: Kali Kaneko
+# Date: 2014 01 26
+#
+# To run, you need to have `imaptest` in your path.
+# See:
+# http://www.imapwiki.org/ImapTest/Installation
+#
+# For the tests, I'm using a 10MB file sample that
+# can be downloaded from:
+# http://www.dovecot.org/tmp/dovecot-crlf
+#
+# Want to contribute to benchmarking?
+#
+# 1. Create a pristine account in a bitmask provider.
+#
+# 2. Launch your bitmask client, with different flags
+#    if you desire.
+#
+#    For example to try the nosync flag in sqlite:
+#
+#    LEAP_SQLITE_NOSYNC=1 bitmask --debug -N --offline -l /tmp/leap.log
+#
+# 3. Run at several points in time (ie: just after
+#    launching the bitmask client. one minute after,
+#    ten minutes after)
+#
+#    mkdir data
+#    cd data
+#    ../leap_tests_imap.zsh | tee sqlite_nosync_run2.log  
+#
+# 4. Submit your results to: kali at leap dot se
+#    together with the logs of the bitmask run.
+#
+# Please provide also details about your system, and
+# the type of hard disk setup you are running against.
+#

+# Edit these variables if you are too lazy to pass
+# the user and mbox as parameters. Like me.
