[c-nsp] Riverbed

[JP Senior]

I use riverbed steelhead appliances on a few links ranging from 40ms to 240ms.
I tend to get about 85% savings on actual traffic that goes through.  I think what is very important to know is the type of traffic you expect to optimize.  Riverbed is -very- good at MAPI and CIFS traffic, which is the majority of what we want to improve.  With the right caching settings and enough disk space you can simply avoid dumping traffic to expensive WAN links and serve it locally, instead.

For standard tcp based apps, it does a great job with window sizing and predictive acknowledgements.
There have been a few applications that we have trouble with the steelheads - particularly VOIP and Video, but these are easy enough to exclude from in-path rules.

It is night and day with and without riverbed.  I don't have experience with the Cisco WAAS product.

I only have experience with Cisco WAAS but if you're on anything with decent latency (<10ms) they caused more (performance) problems for us than they solved. For us the incremental cost of upgrading our bandwidth in most locations was low enough that we didn't take WAAS out of the pilot (and we preferred local services to WAAS where we have poor connections, due mostly to the perceived reliability of those connections). This information is a few years old, though.
