That's interesting.  Can you positively verify a decrease in performance 
between 0.9.4 and 0.9.5?  0.9.5 fixes some important bugs.

If there is definitely a performance decrease there, try backing out the 
changes one by one and find which one caused it.

The first two to try backing out would be the specific GRE bind() and the
sequence number checking change.

Is your pptpd logging anything on the server, eg, heaps of out-of-order
packets?
