An object is limited to one thread. How many qps that is depends entirely on what your app does, since the app can run arbitrary code in the request handler...

Fedora isn't really meant to be a server distro -- it's a bleeding-edge distro so it has rapid releases, a short life-cycle, and lots of new code.
As the Fedora docs say, it's "often running in uncharted innovative territory," which is great if you want the latest stuff on your desktop, but it's not what you really want in a server distro. Red Hat Enterprise Linux (RHEL) is derived from Fedora every few years so it's battle tested and stable, in the same way Debian is.
