Blogbench - A Filesystem Benchmark for Unix (Version 1.2)

Blogbench is a portable filesystem benchmark that tries to reproduce the load of a real-world busy file server.

It stresses the filesystem with multiple threads performing random reads, writes, and rewrites to get a realistic idea of the scalability and concurrency a system can handle.

The architectures supported by this image are:

Architecture	Available	Tag
x86-64	✅	<version tag>
arm64	✅	<version tag>
armhf	❌

Sample Usage

docker run --rm \
    -v `pwd`:/root/results \
    lundberg88/blogbench:1.2 \
    /tmp /root/results/output.prof

Available Options

--commenters=<n> (-c <n>): number of comments posters
--help (-h): usage
--iterations=<n> (-i <n>): number of iterations
--readers=<n> (-r <n>): number of writers
--rewriters=<n> (-W <n>): number of rewriters
--sleep=<secs> (-s <secs>): delay after every iteration
--writers=<n> (-w <n>): number of writers

By default:

• 3 concurrent writers
• 1 rewriter
• 5 commenters
