It shows that your applications are using ~100MB, and almost no swap space use. The important bit is the first number in the "-/+buffers" line. > How is posible my system takes 248 Mb ? if I only have this process: The extra memory is used to cache files so they need not be read from disk repeatedly. > HOW can I evalue the qty of ram that needs my system ? You need more if you start running in to swap a lot, clearly. Elsewise, you'll need to look for bottlenecks in the system and address them appropriately. There's not a lot of generic advice that will always be applicable. If your apps are using the disk a lot, more memory may help by expanding the amount of file/buffer cache available. If they're CPU bound, though, more RAM may not do you any good at all. -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
