[SLUG] Re: Anything like pcAnywhere - some interesting twists



 It can also have to do with ciphers.

 Early versions of ssh used idea. it was fast, moderately secure and patented. Openssh used 3des and blowfish or rhindal (AES). Try setting your ciphers to blowfish for linux to linux work. I know that for scp if gives me up to 3 times improvement on network traffic.
