Ya… using top, I can see whenever
SER is binding users, each child takes around 11% to 13% of the CPU usage,
which left only 0.x% is idle in total (even with dual cpu on the machine)…
and it takes at least few seconds to 30 seconds to bind the users.
When there is no binding, even if UAs
rushing in to register, the CPU usage is around 0.1% to 1.0% in total only. The
CPU usage will suddenly shoot up whenever there is binding.
I tried to use db mode 0 instead, then
everything is alright, binding is fast and CPU usage does not shoot up.
However, I failed to trace the connection
problem between SER and postgresql. Can’t find information from the SER
console.
Is there any way to trace and test it?
I am using currently using ser-0.9.3,
postgresql 8.0 which is located at the other server (both servers at the same
LAN, same subnet).

Chia

cpu usage
Use top to monitor real resource usage while getting
registrations. Some Linux systems' ps command will show each child with
the summed cpu usage of ALL children.
