------------------------------------------------------------
1G links should be able to do over 100MB / sec, so even at 1KB objects, you
should be able to see over 100K QPS. I usually test with 100 byte objects,
which including the header is less than 512 bytes, and it can therefore do
roughly 150-200k QPS depending on hardware.
Also, you should test with caching. But even without caching, a 1G link is
really a ~2G link, since 1G is always full duplex.

> 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.
