You can try it yourself - it's pretty easy to do. Mind you - this is not a veyr compreehnsive test - but the results over a 56K modem appeared quite compelling (over a !0mbit ethernet or a T1 you don't notice that much improvement) Thanks Nate > -----Original Message----- > From: Santosh Kumar [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, October 17, 2000 11:17 PM > To: Orion-Interest > Subject: Re:Orion slower than... > > > Hi Nate, > Do you have some figures to look at? > I mean, How much was the improvement in speed?
