Anthony,
No argument on the core design - this is what differentiates FS from * and what makes things solid. But, on Windows at least, the "one-thread-per-client" concept normally only scales so far (Server normally being a bit better than XP). Not sure about their availability on other platforms, but have you looked at fibers? They seem to be a lighter weight alternative with most of the benefits.

There is no way to avoid this. What are the specs of your machines? DId you try using the 2003 server instead of XP (a home version meant for single users) We have little feedback on performance on win32 (good or bad) but we do have many people using it. Did you do any more extensive profiling to see what is using the most cpu (look for process explorer) 2009/3/26 Richard Lamkin <[email protected]> Dear All, I am testing FS as a call queuing server. My test set up is as follows; Two Windows XP (SP3) Pc's with 1.0.3 installed out of the box. [ Before anyone says use Linux I need to use windows for a specific reason] I have a single gateway [fsb1500] on FS-1 configured to register with FS-2 [extn 1500]. I then use the following CLI command to create a call from FS1[5900] to FS2[5900] "bgapi originate sofia/gateway/fsb1500/[email protected] 5900" This happily connects FS1[5900] to FS2[5900] . Codec set to G711a. I have one hardphone on FS2 with a call connected to 5900 to allow me to listen to MOH. I have been monitoring the system resources used by FS and have observed that for each new call a new thread is created. I have pushed well over 200 calls from FS-1 into FS2. All goes well with the CPU usage by FS (<25%) until 150 concurrent calls when it starts to climb rapidly and at 175 (~50%). One good thing is that memory usage is reasonable with 90MB for 150 calls. My questions are; Q1 - Is my test reasonable ? Q2 - Windows XP is not that happy with large numbers of thread per app. Is there a way to configure FS to use fewer threads; instead of using 1/call can it be configured to use to 1/(n calls) ? Q3 - If there's not a way to configure FS to combine threads would it be reasonable to consider modifying the FS code to allow the combining of threads or would this be a mammoth task.
