Hi All, I do some performance testing with using pjsip-perf and pjsua (v2.0.1 +3rdparty media backend) and found the following lines in pjsua_core.c ----- schnipp --- /* Init caching pool. */ pj_caching_pool_init(&pjsua_var.cp, NULL, 0); ----- schnipp --- This means for me, we are using a caching pool without caching ????? I think it should be something like ----- schnipp --- /* Init caching pool. */ pj_caching_pool_init(&pjsua_var.cp, NULL, 1024*1024*10); ----- schnipp --- for a 10 mb caching pool (for e.g. a high traffic application) Or have the "0" a special meaning ?? -- S E R M O T E C Communications GmbH Harald Petrovitsch harald.petrovitsch at sermotec.at 01/3674174-12 Franz-Kleingasse 3/2 A-1190 Wien
