RE: Regarding the multi threading option in curl loader

[SAJAL B. <s.b...@qu...>]

Hi,

Actually my question was can one thread of Curl Loader use more than one CPU? Like I am using a dual core processor machine and when I don't specify the option -t 2 (since dual core) and monitor the CPU utilization for different number of virtual client (1K, 2K, 5K etc), the CPU utilization does not goes beyond 100%. It reaches around 98% with some 20K clients and after that the programs just crashes. So I am assuming that given my specifications of the machine and my configuration file this is some sort of upper bound. But what I wanted to know is that if with these many clients (20K) its using almost one full CPU (~ 98%) than by increasing the number of clients any further shouldn't it use the other available CPU ?

Hope I am clear in my question.

At a computer with N CPUs (or N-cores) run -t N or -t 2*N.

Fore more details read the FAQs, README and http://curl-loader.sourceforge.net/high-load-hw/index.html
