I always have slowness issues with gerrit, so I just took a quick look at the httpd config and noticed that KeepAlive was off. I turned it on, with a low KeepAlive timeout, and also bumped the max number of workers (since keepalive connections hold workers open).
Ideally we'd switch to a better server than httpd for SSL termination, but that's more work than I have time for. Hoping that the keepalive setting will make things a bit snappier going forward, since we'll avoid a bunch of round trips and small TCP window sizes when fetching page assets, etc. LMK if you hit any issues and I'll revert the change. -Todd -- Todd Lipcon Software Engineer, Cloudera
