bq. Looks like this could be an issue with hardware? Can you please post the
specs of the machine where this was running?
I'm not sure what to chalk it up to beyond hardware. But my test machine is
pretty beefy; it seems like it should be able to handle things, but who knows?
I'm using a Mac Pro with a 14-core "Intel Xeon" processor, 128gb of RAM, and a
SSD for disk. What have you been using for your testing?
bq. Please let me know if you have a branch with the improvements ready that
you want me to test (solr-bench) on the same hardware where I've been running
the tests till now
Yeah, that'd be great, thanks! The branch
[here|https://github.com/gerlowskija/solr/tree/jaxrs-with-partial-fix] rewinds
to the introduction of JAX-RS on main (8efed0) and adds a single commit
(8d6052) that partially alleviates the perf regression. (If you'd prefer
something based on the latest {{main}} or {{branch_9x}} etc, that single commit
should be pretty cherry-pick-able, or I'd be happy to make a branch with a
different base if you lmk.)
