hi,all
i am a newbie to libevent.
i use libevent to build my application's network framework. it works
well. but there are still some questions about it.
data reading from network work very well.
but data i want to write to network are not very reliable when
about 200 clients connect to my server.
i write data to client using method "bufferevent_write" , but
sometimes clients get the data after 7 or 8 seconds.
here are my main code, any suggestion are regarded. thank you!
I doubt your problems are because of incorrect use of
bufferevent_write. I bet one of the following things is happening:
1) You're only getting around to each socket every 7 or 8 seconds.
Try adding some instrumentation to see where the time is going.
(gettimeofday() for wall-clock time, getrusage() for CPU time.) It's
probably in "my_own_biz_code()".
2) You've saturated your network connection. How fast can you send
data, and how fast are you sending data? On Linux, "sar -n DEV 1000
1" will show you bandwidth utilization every second (for 1000 seconds).
