No, don't reboot, it is likely just getting good. Linux doesn't like keeping lots of RAM free, it justs seems like a waste to have RAM sitting there not used for anything, so it uses extra RAM of optional things, like caching disk contents. When you try to read a file it might be in the cache, in which case you will get it much faster. Similar logic applies to IO buffering. If later that RAM is needed for more specific uses it can be taken back from on a moment's notice. Only a little RAM is kept free in Linux, and that is good. -kb -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
