[Wrapper-user] Performance issues

[Vinod P. <vi...@gm...>]

Hi,

I'm using wrapper to manage startup and shutdown of a custom server.
During performance testing of the server, the profiler reports a lot
of cpu utilization in the wrapper methods.

To reduce the wrapper communication, I've set the following values in
wrapper.conf -

wrapper.ping.timeout=0
wrapper.ping.interval=3600
wrapper.cpu.timeout=3600

I know that its not advisable, but this was done to reduce the cpu
utilization reported by the profiler.

But inspite of this, the profiler reports that
SocketInputStream.read() called by wrapper is taking a lot of cpu
time.  On reviewing the code, I found that there's a loop that reads
byte by byte from the wrapper socket.

I'm looking at implementing an alternative mechanism that will not
cause so much cpu utilization.  Suggestions welcome.

Regards,
Vinod.
