It is my understanding that most of the performance increases are from caching. However, they do not cache at the file level like a proxy. They cache at a lower level.
For example, if two excel spreadsheets are 90% similar it would reference the "cached" copy, and just send the 10% differences. It would re-assemble on the other side and pass on to the user.
They work so well that riverbed (we used netdirect systems) will ship eval units for you to try for free. We plugged our eval units in and wrote a check the next day.
We use riverbed appliances at all our remote offices. They take about an hour to install and are damn near like magic.
I just pulled some statistics from one of our remote offices. Over the last 30 days, we had a reduction in data flow of 95% 6.3GB of data went over the T1 instead of 129.3GB
We can run applications over a T1 and users do not know that they are not local. They allowed us to go from DS-3 to T1 lines without any user complaints.

I would go ahead and get the checkbook ready. I doubt you will be dissapointed.
