I'm not sure how many use it like we do, but we make a lot of small round-trips to our state-free appservers. After we upgraded our network to 10 Gbit we expected performance would be much improved on the network level. Unfortunately we didn't see much of a performance change on the HP-UX side, but our Windows-based appservers became quite a bit faster. After we started investigating the reason for the difference in performance between the two platforms, it turned out that a substantial amount of our state-free activity had a huge 50-100 ms overhead per *round-trip* on the HP-UX side, but *nothing* like this happened on Windows. (On the Windows side, our appservers were extremely fast - . ~4 ms - but on HP-UX the same activity was averaging ~60 ms on the state-free round-trips). We reported this initially as an HP-UX-specific bug. But at the end I was extremely surprised to find out that this affects Linux installations of OE appserver too. So I thought I'd put a message out here in case anyone on the Linux platform might benefit from faster appserver calls. IMO you may gain even more by this fix than by other types of optimizations (eg. singleton, single-run, or whatever). http://knowledgebase.progress.com/articles/Article/State-Free-AppServer-Calls-on-UNIX-Linux-May-Perform-Poorly Hope this helps. David these types of things.
