r339 - Server uses ~40% less CPU now - tbar - 02-29-2012 The commit log for rev 339 states: Server uses ~40% less CPU now This sounds amazing!:D How did you pull that off? RE: r339 - Server uses ~40% less CPU now - xoft - 02-29-2012 I guess it depends - it's the amount chopped off of the tick thread, which itself runs at about 5 % CPU on my machine, so that means now it will run at like 3 % CPU I guess But maybe I'm wrong, I myself am wondering about the big change FakeTruth did RE: r339 - Server uses ~40% less CPU now - FakeTruth - 02-29-2012 Apparently the copying of an empty std::map or std::deque 400 times a tick takes a lot of time, so I made a check to see if it contains anything before doing anything else. This brought my CPU from ~10% down to ~6% so, whatever RE: r339 - Server uses ~40% less CPU now - xoft - 02-29-2012 You might save even more if you use std::swap() instead of copying
