Re: Help needed with 3.9 bandwidth/speed problem

As you indicated, it doesn't seem to improve performance when FILTERING packets going between two other machines, only when OpenBSD machines are the endpoints. The difference can be dramatic over a WAN. Or completely non-existent for most people.

I had actually tried that before, but only with using the sysctl command to change it on the fly. I tried again after you suggested it and actually set it in sysctl.conf this time + rebooted. All is now happy. Thanks! --Adam
