While running some high-performance benchmark of a multithreaded application on a 100GE client, we noticed, that although our storage endpoint can deliver 20 GiB/s, a single application was limited to ~2.5 GiB/s data input (single multithreaded application running 85% idle) (streaming many files in parallel) After some investigation, it turned out, that setting: env XRD_PARALLELEVTLOOP=16 allowed to run this application at 5.8 GiB/s This ticket is about the possibility of some automatic configuration of the eventloop size in XrdCl to avoid tweeking the settings for each environment. -- You are receiving this because you are subscribed to this thread.
