( https://gerrit.osmocom.org/c/libosmocore/+/35672?usp=email ) Change subject: Prevent poll() in select.c to timeout too early ...................................................................... Patch Set 1: (1 comment) Patchset: PS1: I have no idea how the scheduler works, but if a process is not running (during poll()), I guess the CPU thread will be directly switched to another process that is running (due to an event). I have an application that uses timer to schedule RTP stream at a rate of 50 frames per second. This is 20 ms delay between frames. Without this patch, the CPU usage at "top" command shows around 5% CPU usage, with a patch (round up or change from 0 to 1) it shows below 1% CPU usage. -- To view, visit https://gerrit.osmocom.org/c/libosmocore/+/35672?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: libosmocore Gerrit-Branch: master Gerrit-Change-Id: I79de77c79af4d50d1eb9ca0c5417123ff760dca3 Gerrit-Change-Number: 35672 Gerrit-PatchSet: 1 Gerrit-Owner: jolly <andreas(a)eversberg.eu> Gerrit-Reviewer: Hoernchen <ewild(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: laforge <laforge(a)osmocom.org> Gerrit-Reviewer: pespin <pespin(a)sysmocom.de> Gerrit-CC: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Attention: Hoernchen <ewild(a)sysmocom.de> Gerrit-Attention: laforge <laforge(a)osmocom.org> Gerrit-Attention: pespin <pespin(a)sysmocom.de> Gerrit-Attention: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Comment-Date: Thu, 25 Jan 2024 18:31:19 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Hoernchen <ewild(a)sysmocom.de> Gerrit-MessageType: comment
