Susan Hinrichs commented on TS-3072:
------------------------------------
[~zwoop] thanks for reminding me of duplexing. My rps had risen above 65K rps
and I has very confused.
[~bcall] agreed that for real performance testing we should be working on
machines with 10G interfaces. For the purposes of this issue though I don't
think we really care about absolute performance. We just need to have an
understanding of the penalty of enabling a IP-specific debug, and verifying
that this code change doesn't affect performance if debug is turned off
entirely.
I'll spend some more time today sorting out my test setup, and post updated
comparisons and add numbers for the cached case as well.

> Presently, when there's a production issue (e.g. TS-3049, TS-2983 etc), it is
> really hard to isolate/debug with the high traffic. Turning on debug logs in
> traffic is unfortunately not an option due to performance impacts. Even if
> you took a performance hit and turned on the logs, it is just as hard to
> separate out the logs for a single connection/transaction among the millions
> of the logs output in a short period of time.
> I think it would be good if there's a way to turn on debug logs in a
> controlled manner in production environment. One simple option is to support
> a config setting for example, with a client-ip, which when set, would turn on
> debug logs for any connection made by just that one client. If needed,
> instead of one client-ip, we may allow configuring up to 'n' (say, 5)
> client-ips.
> If there are other ideas, please comment.
