Using compression flag on the ssh client ?
No. But I've just tried. It slows down a little, but not much. I would say that pictures do not takes 2 seconds but 2.5 seconds. Well. But it's quite far from 1/4 ;)

processing power of either station getting overwhelmed by the bursty
graphics demands.
Also I tried with blowfish option, but this give me absolutely the same speed than with the default 3des.

But well I'm using cygwin, so perhaps it comes from here. In fact :
- software server is on FreeBSD
- *but* X server is on the Windows PCs

I don't know how the computers deals with that, since all thing related to X are not set on the FreeBSD PC, and as far as I see, it does not need to.


I was also thinking about tcp send space, since I let the default 32K for now.
I've read the handbook about optimizing that but they say that :
- if applications are network intensive, have to increase sendspace and rcvspace (it seems that that's my case)
- if they are not to many connections, increase sendspace (that's my case)
- up to 65536, have to check that remote PCs (Windows PC) support rfc1323 if I understand well
but the handbook won't tell how much I should give, and I'm sure that it's might be some experience related settings, but I'm a newbie...
What would be a good value ? Should I only test ? Do I need to reboot after having set those values using sysctl ?

Thanks,

Raphael
