MongoDB and a best performing OS?

[s.molinari]

Hi,

I know MongoDB supports multiple OSes. But is there any certain Linux variant, which is actually most recommended (maybe inofficially) as the one, which will perform the best with/for MongoDB? Has anyone done any benchmarking between Linux OSes?

Ok, I've read this.

http://docs.mongodb.org/manual/administration/production-notes/

But still, is there a Linux OS that works best with Mongo? Or does it really not matter?

Hi Scott. We don't have any preferred Linux distribution. As you've read in the production notes, we have some recommendations for different flavors of Linux, but MongoDB can work well on all mainstream ones. As part of our release process we currently provide Linux packages for Redhat/CentOS, Ubuntu, Amazon Linux, and SUSE

Thanks Will. So can any new MongoDB user conclude that MongoDB will perform equally well on any of the supported Linux distros, as long as it is properly configured for Mongo?

Hi Scott!

MongoDB performance is remarkably insensitive to Linux distro version.   The only place that I can think of that would make a difference is changes that would affect either paging behavior or disk subsystem performance.  For the most part, if you tune the equivalent kernel versions the same way, and remaining differences would just be rounding error.

Thanks William. Then we'll most likely stick to Debian.:)
