I think the first thing I would do is go back to a default
configuration. Turn off pf, take out all of the sysctls and see what
happens. Then start adding things in one at a time until you find
what breaks it. It doesn't take much to do 625K/sec, the default
configuration is easily capable of 30 times that. My guess is that
either one of the sysctl 'tunings' has broken something, or an
interaction between two or more of them has caused an unexpected
behavior, but that's an easy enough theory to test.
