Subject tuning concurrent_reads param
Date Thu, 30 Oct 2014 03:41:42 GMT
Hi,
looking at the docs, the default value for concurrent_reads is 32, which
seems bit small to me (comparing to say http server)? because if my node is
receiving slight traffic, any more than 32 concurrent read query will have
to wait.(?)

Recommend rule is, 16* number of drives. Would that be different if I have
SSDs?

I am attempting to increase it because I have a few tables have wide rows
that app will fetch them, the pure size of data may already eating up the
thread time, which can cause  other read threads need to wait and essential
slow.

thanks
