Your servers seems to be about the right size, but as everyone else has said, it depends on the kinds of queries.
Solr should be the only service on the system. Solr can make heavy use of the disk which will interfere with other processes. If you are lucky enough to get the system tuned to run from RAM, it can use 100% of CPU. Tuning Solr will be very difficult with other services sharing the same system. If you need to meet an SLA, you will have a hard time doing that on a shared server. When you don't meet that SLA, it will be almost impossible to diagnose why. Why not Windows? * the Windows filesystem is not designed for heavy server use * Windows does not allow open files to be deleted -- there are workarounds for this in Solr, but it is a continuing problem * the Windows file cache is organized by file, not by block, which is inefficient for Solr's access pattern * Java on Windows works, but has a number of workarounds and quirks * the Solr community is almost all Unix users, so you will get much better help on Unix wunder On Mar 8, 2013, at 3:04 AM, Upayavira wrote: > If you are attempting to assess performance, you should use as many > records as you can muster.
