Re: D state when high load on same static file.

December 22, 2011 04:24AM
I have tried : sendfile, aio, directIO with the same scenario, same buffer size, ...
But it seems that directIO is the best, when I turn to Aio or sendfile, the output bandwidth become less than directIO (about 200Mbps, just 10% compares to directIO )

Is there anything tweak that relates to this problem ?

Thanks all guys.
