Cool, thanks for reporting and testing!

The fix nor the previous commit will result in performance increase for sure, since they are adding malloc and free to every xfer request, other than before. But it also shouldn't lead to dramatic performance decrease. I did test a 1GB file transfer through scp with and without the fix, and the transfer speed did remain the same for both. I guess your performance drop was related to other factors.
