[Exist-open] Parallel transform performance tuning

[Len S. <le...@wi...>]

Where can I see/control/test how many parallel XQL transactions and more importantly how many parallel XSL transforms can be done by Saxon on my server?  I’m sending transactions using REST.

  *   I see the database connection pools in etc/conf.xml at /exist/db-connection/pool/@max.  What are the implications of setting @max > 20?
  *   Where can I see/control the HTTP connection pools?  Is that in etc/jetty/jetty-threadpool.xml at /Configure/New/Set[@name=‘maxThreads’]?
  *   Are there any Saxon configuration settings that I should know about?

Any suggestions for how to test how well my machine responds to parallel XQL queries containing XSL transforms?  E.g. do you have any hints how to create a long-running XSL to see how well my server responds?
