We sometimes get a spike in Solr, and we get like 3K of threads and then
timeouts...

In Solr 5.2.1 the defult jetty settings is kinda crazy for threads - since
the value is HIGH!

What do others recommend?

Fusion jetty settings for Threads:


    <Get name="ThreadPool">

      <Set name="minThreads" type="int"><Property name="threads.min"
default="10"/></Set>

*      <Set name="maxThreads" type="int"><Property name="threads.max"
default="200"/></Set>*

      <Set name="idleTimeout" type="int"><Property name="threads.timeout"
default="*60000*"/></Set>

      <Set name="detailedDump">false</Set>

    </Get>



This is better than SOLR default:


  <Get name="ThreadPool">

    <Set name="minThreads" type="int"><Property
name="solr.jetty.threads.min" default="10"/></Set>

    <Set name="maxThreads" type="int"><Property
name="solr.jetty.threads.max" default="10000"/></Set>

    <Set name="idleTimeout" type="int"><Property
name="solr.jetty.threads.idle.timeout" default="5000"/></Set>

    <Set name="stopTimeout" type="int"><Property
name="solr.jetty.threads.stop.timeout" default="60000"/></Set>

    <Set name="detailedDump">false</Set>

  </Get>
