Re: [SR-Users] Kamailio best performance

Hello list. I'm having some issues with the Kamailio versión 3.2.0. I want to ask if someone could give some hints how to optimize the performance of my kamailio server. For some reason and from time to time the kamailio process start to answer slower than usual, making calls fail and register expires. I'm still unable to detect the problem, but I want to know of maybe i´m running my kamailio not under the best conditions. This is part of my configuration : #!KAMAILIO #!define FLT_NATS 5 #!define FLB_NATB 6 #!define FLB_NATSIPPING 7 # ----------- global configuration parameters ------------------------ debug=2 # debug level (cmd line: -dddddddddd) fork=yes log_stderror=no # (cmd line: -E) log_facility=LOG_LOCAL0 children=16 port=5060 memdbg=9 memlog=9 listen=udp:10.0.10:5060 disable_tcp=yes server_signature=0 port=5060 # ----------------- setting module-specific parameters --------------- ## modparam("registrar", "received_avp", "$avp(s:rcv)") modparam("usrloc", "db_mode", 1) modparam("auth_db", "calculate_ha1", 1) modparam("auth_db", "password_column", "password") modparam("rr", "enable_full_lr", 1) modparam("auth_db|permissions|uri_db|usrloc","db_url","mysql://openser:openserrw@localhost/openser") modparam("permissions", "db_mode", 1) modparam("permissions", "trusted_table", "trusted") modparam("avpops", "db_url", "mysql://openser:openserrw@localhost/openser") modparam("avpops", "avp_table", "usr_preferences") modparam("domain", "db_mode", 1) # ----- nathelper params ----- modparam("nathelper", "natping_interval", 20) modparam("nathelper", "ping_nated_only", 1) modparam("nathelper", "sipping_bflag", FLB_NATSIPPING) modparam("nathelper", "sipping_from", "sip:pinger@kamailio.org <mailto:sip%3Apinger@kamailio.org>") # params needed for NAT traversal in other modules modparam("nathelper|registrar", "received_avp", "$avp(RECEIVED)") modparam("usrloc", "nat_bflag", FLB_NATB) modparam("nathelper","natping_interval", 20) ## modparam("nathelper","received_avp", "$avp(i:42)") modparam("mediaproxy","mediaproxy_socket", "/var/run/mediaproxy/dispatcher.sock") modparam("mediaproxy", "signaling_ip_avp", "$avp(s:signaling_ip)") modparam("registrar|nathelper", "received_avp", "$avp(i:80)") modparam("mi_fifo", "fifo_name", "/tmp/kamailio_fifo") #modparam("tm", "fr_timer", 3) # ------ dialog params ------- modparam("dialog", "dlg_flag", 4) modparam("dialog", "profiles_with_value", "caller") # ------ pike params -------- modparam("pike", "sampling_time_unit", 2) modparam("pike", "reqs_density_per_unit", 25) modparam("pike", "remove_latency", 4) # ------ rr params -------- modparam("rr", "enable_full_lr", 1) # ----- misc_radius params ----- modparam("misc_radius", "radius_config", "/usr/local/etc/radiusclient-ng/radiusclient.conf") modparam("misc_radius", "caller_service_type", 18) modparam("misc_radius", "callee_service_type", 19) modparam("misc_radius", "caller_extra", "Called-Station-Id=$ru") modparam("misc_radius", "callee_extra", "Called-Station-Id=$fu") # ---- htable param --------- modparam("htable", "htable", "a=>size=8;") modparam("htable", "htable", "ipban=>size=8;autoexpire=300;") modparam("rtimer", "timer", "name=tst;interval=300;mode=1;") modparam("rtimer", "exec", "timer=tst;route=STATS") modparam("sqlops","sqlcon", "ca=>mysql://openser:openserrw@localhost/openser") #------ uac --------------- modparam("uac","rr_store_param","my_param") modparam("uac","from_restore_mode","auto") modparam("uac","auth_realm_avp","$avp(i:10)") modparam("uac","auth_username_avp","$avp(i:11)") modparam("uac","auth_password_avp","$avp(i:12)") Beside of this I have syslogd in asyn mode...

Or intensive in mysql access request??
