baracus

httperf wrapper for benchmarking CouchDB

Features:

• Results sent to CouchDB and printed in TSV
• Creates wsesslog files dynamically using random data for document writes and _all_docs for reads
• Lots of knobs: session counts, document size, request rate, etc
• httperf session work logs are attached to results for replaying later

License:

This code is available as Open Source Software under the MIT license.

Usage:

$ gem sources -a http://gemcutter.org $ gem install baracus $ baracus /path/baracus.yml

Suggestions:

• Set "ulimit -n 65535" before running baracus
• Change FD_SETSIZE to 65535 in /usr/include/bits/typesizes.h before compiling httperf
• For tests with more than 1000 sessions increase MAX_SESSION_TEMPLATES in gen/wsesslog.c before compiling httperf
