[httperf] problem with request number

Hi Fane

As Chris pointed out, the issue is 206 of your 300 connections have been reset, i.e., prematurely terminated by the server before they have completed 1,000 calls. Thus, your math is incorrect, you are adding the number of calls completed and the number of connections reset. You would need to multiply the number of connections reset by the average number of calls still to be sent on each of those connections.

Thanks
Martin

thank you for the answer, but :
"Total: connections 300 requests 246524 replies 246318 test-duration 27.424 s"



"Errors: total 206 client-timo 0 socket-timo 0 connrefused 0 connreset 206"

the errors are 206 , they correspond to the failed replies (infact 246318+206= 
246524) but i want that httperf server send all the 300000 requests .
