Slowdown with roundup 2.3.0 vs roundup 2.1.0?

Hi all:

In private email Norbert Schlemmer and I have been debugging an issue
where his 2.1.0 docker installation runs much faster than his 2.3.0
docker install.

Both of them are deployed using roundup-server. He is seeing a 1.7 or
so second delay in the REST interface under 2.3.0 that is not present
under 2.1.0.

The @stats=true query param provides stats that look pretty much the
same for both 2.1.0 and 2.3.0 (sub .05s elapsed time) . However the
times produced by @stats seems to be much less than the times measured
say using curl (1.5s or so).

Has anybody seen a similar slowdown in their 2.3.0 deployments by any
mechanism?

I have a sneaking suspicion that it is due to the change to HTTP/1.1
in roundup 2.2.0, but even running with -V HTTP/1.0 doesn't seem to
totally solve the issue.

Also if anybody has patches to better instrument roundup or
roundup-server, I would like to see them.

Have a great day all. FYI, I'll be AFK on Friday.
