Peter - It's primarily the network bandwidth. The best-case latency to Asia from the US is about 150ms (assuming speed-of-light, no hardware delays). What we see on bi-directional traceroutes is an "across-the-ocean" delay of 200ms to 300ms on a good day. That translates to adding roughly 1 second to response time. Depending on the page, we probably run from 8k to 1-2 Mb of text. And that doesn't include uploads/downloads of user's files. Jeff

To the OP: What's the bottleneck in your environment? CPU? Disk I/O? Network bandwidth? Measure the problem, *then* look for solutions to the problem that actually exists. If you've measured and you have CPU to spare but are bandwidth-limited, then compression will help a great deal! - Peter ******************************* NOTICE ********************************* This message is intended for the use of the individual or entity to which it is addressed and may contain information that is privileged, confidential, and exempt from disclosure under applicable law.
