compress before encryption and the transmission speed depends on content. If it's something that compress's well your throughput should increase. I use a zlib compressed encrypted vtun for my dsl line and on plain text I get about a 300% increase in speed with zlib set to fastest compression (level 1), but things like jpgs are even. I also don't see latency issues, I play quake3 over it just fine adds maybe 1msec. Eric
