Q:

Solr - Is the "maxWriteMBPerSec" config value in megabytes or megabits?

The documentation doesn't define whether the "maxWriteMBPerSec" uses megabytes, or megabits. I presume it's bytes and bits would be small, but could someone please confirm?

A:

It's in megabytes. From the Lucene source code for RateLimiter.SimpleRateLimiter:
double secondsToPause = (bytes/1024./1024.) / mbPerSec;
