[SR-Users] notify takes several seconds to generate

[Juha Heinanen]

i noticed that kamailio 4.3 presence server takes several seconds to
generate notify when it receives subscribe request. for example:

Dec 27 15:42:01 lohi /usr/bin/sip-proxy[7363]: INFO: Routing SUBSCRIBE <sip:test at test.tutpro.com> to presence server at <sip:127.0.0.1:5080;transport=tcp>
Dec 27 15:42:01 lohi /usr/bin/pres-serv[7113]: INFO: Handled SUBSCRIBE <sip:test at test.tutpro.com>
Dec 27 15:42:05 lohi /usr/bin/pres-serv[7108]: INFO: Routing locally generated NOTIFY <sip:test at test.tutpro.com;gr=urn:uuid:47759291-c9db-4eb3-a540-5e68353414ee> to <sip:test at test.tutpro.com> from <sip:test at test.tutpro.com>

the host is not loaded at all. these relevant presence server params are
set:

modparam("presence", "subs_db_mode", 3)
modparam("presence", "db_table_lock_type", 0)

and db is on localhost.

any explanation why notify takes so long to generate?
