Slow performance over VPN/cable modem

["Bruce A. Hamilton" <bhami at pobox dot com>]

XP Pro SP1, Pentium 2.66 GHz, 1 GB memory.

I am running the latest cygwin including XFree86 4.3.0.

Performance connecting to my workplace via VPN over cable modem is 
painfully slow, similar to what I used to see running X over dialup years 
ago. I'm running a local window manager fvwm2 then "ssh -X" to hosts at 
work via my local xterms.

The app I'm most interested in is Veritas NetBackup 4.5 jnbSA, which is 
written in Java and not exactly speedy even at work, but at work we are 
talking a couple of seconds to refresh the screen, versus nearly a minute 
for the tiniest changes at home.

My Internet connection in general is very fast, on the order of 2 Mb/sec, 
and I get excellent response over my VPN to work using vanilla text apps 
and MS Outlook.

Thanks for any suggestions. I'm quite sure this in an X issue. Wasn't MIT 
supposed to be working on "low-bandwidth X" years ago?

Three years ago I had the good fortune to be able to use Graphon's 
Go-Global to channel X over dialup and was VERY impressed.

More recently I played a little bit with VNC and it seemed to have its own 
performance issues so I have no pursued it further at this time, but I'll 
consider it if you recommend it.
