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.
