    Default 5.02 memory use query

    since upgrading to 5.02 RHEL_64ne, the system swap use is ~70% and the load quite high, this reaches ~ 100% when we run netbackup at 6am on /opt/zimbra/backup.

    The server is quite beefy 4G RAM, 2G Xeon processor, 1T disk space.

    The system has ~ 4000 active users any suggestion on how to improve the system,
    or does it still require extra ram.
    thanks for any replies

    Did you look here: Performance Tuning Guidelines for Large Deployments - Zimbra :: Wiki ?

    First thing IMHO would be to disable swap and add RAM (for 4000 users, 4 GB seems "low" to me).

    Thanks Klug,

    will look at the wiki but i'm surprised 4G isn't enough, the max logged in is ~100 users
    and the swap is ~70 even at 3am
