Note: while this blog post uses some Linux commands in its examples, mongoperf runs and is useful on just about all operating systems.
mongoperf is a utility for checking disk i/o performance of a server independent of MongoDB. It performs simple timed random disk i/o’s.
mongoperf has a couple of modes: mmf:false and mmf:true
mmf:false mode is a completely generic random physical I/O test — there is effectively no MongoDB code involved.
