Database performance question (MySQL or PostgreSQL?)

Howdy! Please let's not let this turn this into SQL wars. =) I'm sure this issue has been discussed several times before but I'm unable to find anything about it in the snort-users archives. I'm currently running several Snort sensors with a central MySQL database. Recently the database speed has become a problem. When the number of alerts is starting to reach 100 000, ACID is starting to get slow. Add another 100 000 alerts and ACID is almost unusable. My database server is not doing anything else but running MySQL and ACID. Here are the specs: - Pentium II 450 MHz (normally almost totally idle, jumps to 80% when making SQL queries) - 384 RAM (about 50% used, jumps to 60-70% when making queries) - 7200 RPM IDE HD (yes, I know...) As CPU and RAM utilization is almost never higher than 80% and still the queries take awfully long to finish, could the HD be a problem? I remember seeing discussions about differences between MySQL and PostgreSQL performance. If I remember correctly, PostgreSQL was believed to be somewhat faster. Could anybody with some real life experience on this issue share hers/his knowledge? Thanks! - Jyri ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Snort-users mailing list Snort-users () lists sourceforge net Go to this URL to change user options or unsubscribe: https://lists.sourceforge.net/lists/listinfo/snort-users Snort-users list archive: http://www.geocrawler.com/redir-sf.php3?list=snort-users
