  • Question regarding memory usage (swap, buffers)

    On my new server currently used as test, we are still experiencing awfully slow queries.

    I ran free -m and the result is:

    new server (1 user browsing)

    Code:
    # free -m
                 total       used       free     shared    buffers     cached
    Mem:          2048       2008         40          0          8       1566
    -/+ buffers/cache:        433       1614
    Swap:         2047          0       2047
    while with our "old" server (>500 users browsing), that runs just fine, we have:

    Code:
    [oldserver ~]$ free -m
                 total       used       free     shared    buffers     cached
    Mem:          2048        701       1346          0          0          0
    -/+ buffers/cache:        701       1346
    Swap:            0          0          0
    I am no expert in this, how can I interpret this values? Could be this the reason for slow queries?
