Mersenne: Linux VFAT question
Hi, Jan Scheller is having a problem (see below). Are there any Linux users that can provide help? Please include Jan in your reply as Jan is not subscribed to this mailing list. I've already recommended the "poor man's" solution of having mprime not write to disk every 30 minutes. Best regards George snip But the fact is that the performance of my mounted hdd win98 (vfat) partition is very low. All my normal linux (ext2) partitions work with normal performance. If I execute a command like `ls -l /Win98` (/Win98 is the path of may win98 (vfat) partition) it takes more than a second to get the result. The second points is, that the swapping seems to be slower than without running mprime. I run mprime every time at the lowest priority. Is there possibility to rise the performance of my vfat partition while running mprime? Unsubscribe list info -- http://www.scruz.net/~luke/signup.htm

This tells you how many files the directory has. The more files, the longer it takes to sort them. vdir -U lists the directory without sorting it, which is a little faster. mprime just writes once every 30 minutes, so whether it's running in the Windows drive or the Linux drive is inconsequential. As to the swapping, the swap daemon runs at 12 naughty, so I don't see why mprime at 20 nice would bother it at all. phma Unsubscribe list info -- http://www.scruz.net/~luke/signup.htm

Do you mean that your vfat access is slower in general when running mprime? Or just when you just have started mprime, and it's reading the p-file from disk? And what is this `swapping' you're talking about, is that disk access? (A simple but ugly solution would be storing all your mprime files (INI-files, p/q files, etc.) on an ext2 partition, and copy them to/from the vfat partition automatically on boot and reboot. (How you do this depends a bit on your distribution.) Of course, if you don't use Windows very much, you could drop `Windows support' totally.) /* Steinar */ Unsubscribe list info -- http://www.scruz.net/~luke/signup.htm
