http stats
Hi,
I see this comment in records.config
##############################################################
# The HTTP stats are expensive, turn off you don't need them #
##############################################################
CONFIG proxy.config.http.enable_http_stats INT 0
Are there any actual numbers published on how expensive the http stats are?
I am thinking of enabling them and would like to know the penalty if
possible. Thanks.
Dk.

No numbers, but you should benchmark and share! :-).
I don’t know of anyone *not* using the HTTP stats in production. The default is also “1”. We probably should change that old comment …

We have never run without stats on a production machine to my knowledge. Also, I have never seen stats come up as using a lot of CPU while profiling when running a benchmark. The comment should definitely be changed.
