Thank you, Maarten. I tried to upload the callgrind data, but the email was rejected due to its size. Glad you can reproduce the slowness!
Now the question is: what's to cause of the socket slowness, compared to the pipe performance? Based on yesterday's findings, this might not be a LO issue afterall. Connecting to LO through a pipe gives me the same performance (and faster) that I have on my Mac. It's the socket connect which is so slow. See here for more data: https://forum.openoffice.org/en/forum/viewtopic.php?f=20&t=74332&p=336914#p336975 The question lingers: why is socket connect on Linux so tremendously slower than on the Mac... http://superuser.com/questions/860321/linux-localhost-sockets-painfully-slower-than-on-mac Jens On Mon, Jan 05, 2015 at 06:36:47PM +0100, Maarten Hoes wrote: > Hi, > For what its worth, i can easily reproduce the script takes fairly long > (about ~50 seconds on my vm's) to complete on both Ubuntu 14.04 and > Fedora 21, both with the distro supplied binaries and a recent master. > I ran the script using strace -f.
