performance issues with 9.5.0-P1

[Jim Gogan]

Just to update the curious out there: thanks for the folks that 
suggested increasing the number of file descriptors available for the 
process and increasing the max-cache-size.   Going from the default 256 
to 4096 file descriptors available and using 512M for max-cache-size had 
a noticeable impact in reducing the load on our systems since moving to 
9.5.0-P1.

The load is still higher than I'm really comfortable with, so we will be 
looking at implementing one of the beta versions that addresses 
performance issues.   However, at least now we've got breathing room and 
minimal-to-no user impact.

Thanks all!
