#25461: main event-loop spins consuming 100% of a CPU core at times --------------------------+------------------------------------ Reporter: Dhalgren | Owner: (none) Type: defect | Status: new Priority: Medium | Milestone: Tor: 0.3.4.x-final Component: Core Tor/Tor | Version: Tor: 0.3.3.3-alpha Severity: Normal | Resolution: Keywords: performance | Actual Points: Parent ID: #25500 | Points: Reviewer: | Sponsor: --------------------------+------------------------------------ Changes (by nickm):
* keywords: regression?, performance, 033-must? => performance * parent: => #25500 * milestone: Tor: 0.3.3.x-final => Tor: 0.3.4.x-final Comment: ... but the last comment indicates that it is probably not a regression. I think we might be able to look at this as part of #25500, though, since anything that can make the main loop run wild without actually taking any action is something that could maybe affect clients too. One hypothesis is that we should be marking some connection as blocked, but that we aren't, so we are busy-polling on it. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/25461#comment:4> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
