You are remembering correctly. One time on the old Phantom I ran ApacheBench for a few minutes to test our web-site code. It cranked the swap usage up so high that the load average stayed above 4 for over an hour. I was afraid I had brought the system to its knees. It kept on trucking: Phantom was tough. One of the reasons we are using so much memory now is that we are storing a lot of data in MySQL to make MUG more portable (images, resumes, etc). This requires that mysqld run with a biggger memory footprint (since the max_packet_size is higher). Right now the system is using 75Mb (plus 45Mb cached). You can check out the sysinfo here: http://phantom.byu.edu/ The added RAM will serve as a buffer for high load. If you hit the site with ab, or open simultaneous ftp downloads, or run several apt updates, we'll begin to use that extra RAM. Also, if it's barely enough now, how long will it really last? The old Phantom lasted (by carbon dating) roughly 5 years. That was a sturdy machine. We'd like this one to serve with similar longevity. By the way, is there a way to tell how much memory a process tree is using (like 'ps afx' with memory totals)? --Dave ____________________ BYU Unix Users Group http://uug.byu.edu/ ___________________________________________________________________ List Info: http://phantom.byu.edu/cgi-bin/mailman/listinfo/uug-list
