Paul Elschot commented on LUCENE-1410:
--------------------------------------
Did you see any effect of the JIT? This is possible by making a loop that runs
for about 1 second, and use that loop 3 times, see the output posting of 3 Oct
2008. When the 2nd and 3rd time are just about equal one can assume that the
JIT is done.
Perhaps a shorter time than 1 second can be used nowadays.
For the blocks that you've been measuring one might also see an effect of L1/L2
data cache size.
This effect is probably not present in my previous postings here because I have
not yet used this on larger blocks.
