Blogbench is a portable filesystem benchmark that tries to reproduce the

load of a real-world busy file server.

Blogbench stresses the filesystem with multiple threads performing random

|
reads, writes and rewrites in order to get a realistic idea of the
|
|
scalability and the concurrency a system can handle.
