Travis Woodruff commented on PIG-3654:
--------------------------------------
Daniel, I can't think of a reason for setting classCacheEnabled to false. I
added it primarily so I could add the enabled vs disabled test. If we're
satisfied with the approach, I can remove the flag.
Rohini, do you mean an assert on absolute max time (e.g., 500 ms)? I thought
about adding that, but I was worried that load on the build server might cause
it to fail in the absence of an actual performance regression. Happy to add it
if you don't have that concern.

> While benchmarking compile time for a large scripts, I noticed that class
> lookups for UDFs accounted for a significant amount of time. Adding a simple
> cache for looked up classes would speed up compile time noticeably.
