I’m not understanding how vprof is related to the console problems you described. Would you mind clarifying?
If you’re reliably able to reproduce a spike, would it not be possible to turn on vprof spike mode, get a report, and then turn vprof off. If the spikes are really huge, then just set the threshold really low.

There's con_logfile, but once that starts, it cannot be stopped. I had a 90MB~ log file after a couple hours, which isn't fun on an SSD. vprof needs to write files/dumps automatically to disk in order to become useful for servers. Thanks, Kyle.

This sort of problem is pretty much exactly what it was designed to investigate. E.g. vprof_on vprof_dump_spikes 20 // dump a vprof report if frame rate drops below 20 If the problem is caused by network traffic, using the -netspike command line argument can also be used to dig deeper into exactly what entity data is being sent. If you have a report and you don't know how to interpret it, you can email it to me or post it here, I'm sure there are some people who can help analyze it. -----Original Message----- From: hlds_linux-boun...@list.valvesoftware.com<mailto:hlds_linux-boun...@list.valvesoftware.com> [mailto:hlds_linux-boun...@list.valvesoftware.com<mailto:hlds_linux-boun...@list.valvesoftware.com>] On Behalf Of Bjorn Wielens Sent: Monday, May 13, 2013 9:42 AM To: Half-Life dedicated Win32 server mailing list; hlds_li...@list.valvesoftware.com<mailto:hlds_li...@list.valvesoftware.com> Subject: Re: [hlds_linux] [hlds] TF2 server performance spikes Correct, I was one of the folks discussing this in the last round of messages and we run on Linux. Since my last message about having disabled replays I still get occasional hiccups in a full server, but nowhere near as bad as before, owing to the lack of replay overhead. I'd be happy to run diagnostics if they were available for Linux, but alas that's not the case. ________________________________ From: Alex Kowald <abkow...@gmail.com<mailto:abkow...@gmail.com>> To: Half-Life dedicated Win32 server mailing list <hlds@list.valvesoftware.com<mailto:hlds@list.valvesoftware.com>> Sent: Monday, May 13, 2013 1:16:04 PM Subject: Re: [hlds] TF2 server performance spikes You are only accepting traces for windows servers correct? Some of the people that have complained are running linux. I have the issue myself on two independent servers. We get this new game studder after upgrading, leaving everything else the same.
