Change subject: Configure PoolCounter for search requests
......................................................................
Configure PoolCounter for search requests
Requires I1298bc70 to be live to function.
- Set workers to 78. Lucene has a thread pool of 80, so use most
of them without overloading it.
- Set the max queue to 400. This is roughly half the possible requests that
it would take to overload the apaches. 6 Lucene * 800 max queue = 4800
processes, which is the number of regular apache processes in eqiad.
- Leave timeout default 0.5s for now
