I did the test when I start looking at FS. With 10 000 files in conf/directory/default mounted as a ramdisk (if not in Ramdisk, the IO are too high) and an intel quad core q9550 (2.83Ghz) with 4GB RAM and the db also in Ramdisk, I was stuck at approx 150cps with a very high CPU usage. The version I used was 1.0.1, but not sure. Anthony Minessale wrote:

If someone interested I have few numbers on Registrar performance:
DB server: 2x Quad core E5345 @ 2.33GHz, 16 GiB RAM Centos 5 x86_64, MySQL 5.0
Registrar server: 2x Quad core E5345 @ 2.33GHz, 16 GiB RAM Centos 5 x86_64
Tested using sipp with 10.000 and 30.000 "users".
FreeSWITCH as registrar - current trunk: 1. FreeSwitch si simply modified (code doing NAT-ping is commented out :-) 2. Directory is served through lighttpd and simple "C" binary doing one trivial select. Lighttpd runs on the same machine as FS. When I move lighhtpd to another machine, I cannot see any significat performance boost.
Result: I can go up to the 470-500 reg/s. and FS is heavy overloaded and retransmissions occurs.
Kamailio as registrar - 1.4.3. no TLS: 1. Kamailio runs with usrloc db_mode 3 (no caching)
Result: I can go up to the 3500-3700 reg/s. and Kamailio server is at 0.3 load and all 8 cores are bellow 15 %. Without retransmissions. The limit is DB throughput. Just for "curiosity" I switched userloc to db_mode 2 (write back) and at 5000 regs/s I stopped the sipp test, because I saw the bottle neck becomes the server runnig sipp (very old P4 box).
Conclusion: While I see amazing FreeSWITCH performance on INVITEs per seconds and concurrent calls (another galaxy from * point of view :-), if you have to handle lots of registrations per second, it is IMO better to use Kamailio/OpenSIPS/SER as separate registrar and "propagate" users to FS through SQL view.
Hope this helps someone...
