From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4) Gecko/20030624 Description of problem: If I don't log in to the console and leave the computer idle for a period of time (>15 minutes?) the performance becomes very slow via remote access to the machine via ssh. Performance is between 8-12 times slower than if console is active (no screensaver active). Deactivating screensaver but not logging in to console returns performance to normal. Version-Release number of selected component (if applicable): kernel-2.4.22-1.2087.nptl How reproducible: Always Steps to Reproduce: 1. Boot up machine, compile code using ant or running hdparm -t -T /dev/hda either logged into console or via ssh. Performance is great (probably better than under 7.3 which was the last RHL on the machine). 2. Leave machine running for a period of time, screen saver or equivalent kicks in, runlevel 3 or 5. Ssh into box and compile code using ant or run "hdparm -t -T /dev/hda". Performance is noticably slower, java takes 10-12 times longer, hdparm shows performance is 8-10 times slower from step 1. 3. Stay connected via ssh, hit left arrow button on X terminal to bring up login screen, do nothing else on console. Run same tests as above via ssh. Performance returns to normal. I haven't tried this under runlevel 3 but will in the morning. Actual Results: Slow performance when machine is inactive Expected Results: Normal performance when machine is inactive Additional info:
Which screensaver specifically is running, and is it a GL screensaver? If it's random or you're not sure, can you please check the output of ps and find out which saver is running at the time? Alternatively pick a single screensaver out of the bunch. Try to determine which if any particular screensaver makes a difference. That should help to determine if it is the screensaver application itself or perhaps something else at fault. If it only occurs with OpenGL screensavers, then please attach your X server log, X server config file, and a copy of /var/log/messages as individual uncompressed file attachments using bugzilla file attach below.
screensavers run at +10 by default. It's configurable.
