examples/light-server changes

Options added to help with library performance measurements.
E.g. Run top to see CPU usage and send 1000 toggle commands with 50ms delay:
gupnp/examples$ ./light-server -q
gupnp/examples$ ./light-client -q -c 1000 -d 50 toggle


gupnp/examples$ ./light-client --help
Usage:
  lt-light-client [OPTION...] [on|off|toggle]

Help Options:
  -h, --help                     Show help options

Application Options:
  -q, --quiet                    Turn off output
  -c, --repeat-counter=value     Repeat counter
  -d, --repeat-delay=value       Delay in [ms] between each iteration

gupnp/examples$ ./light-server --help
Usage:
  lt-light-server [OPTION...]

Help Options:
  -h, --help       Show help options

Application Options:
  -q, --quiet      Turn off output

Updating light-server patch, replaced FALSE with NULL in GOptionEntry table.

Which performance is this supposed to test? GUPnP?
Comment 4 Andrzej Bieniek 2013-09-30 22:35:00 UTC 
yes, it allows to measure CPU usage with various UPnP commands frequency.

It may be useful to get it into the code, so it can be run on different platforms and results could be compared - on the PI CPU usage looks quite high.

E.g. CPU usage for toggle command on raspberry PI (as reported by htop):
toggle every 20ms: client 40% CPU, server 30% CPU, tatal 70% CPU
toggle every 40ms: client 30% CPU, server 20% CPU, tatal 50% CPU
toggle every 60ms: client 22% CPU, server 17% CPU, tatal 39% CPU
toggle every 80ms: client 18% CPU, server 15% CPU, tatal 33% CPU
