This looks 100% normal. Notice the "22884668k cached" entry. This is memory allocated to disk caching but will be released (WITHOUT writing it to the swapfile) as needed. In effect it's free memory, but the system knows it has disk blocks in it (and which ones) so if you were to happen to read one of those blocks again it wouldn't have to go a disk I/O. For all other intents and purposes, it's free memory. It sounds from your description like the problem is I/O and has nothing to do with memory. If it were memory, the "swap used" number would be MUCH larger. No swapping is happening on your system. -- Jim Garrison ([email protected]) PGP Keys at http://www.jhmg.net RSA 0x04B73B7F DH 0x70738D88 _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
