sorry as I forgot to post the question in my earlier post
Please find the question below :

why performance
of streaming throughput increased when piped with top command.
senario:
$ ./task_run
http streaming media server to client renderer
lots of threads running shown in below snapshot
seems to be decoder task is starving but, http task also has enough
data
result: video is choppy

$ ./task_run | top

surprisingly improved performance no choppy video
skanth.
searched in google .. heard about a same problem in this link
