    Average of 4.6 seconds / request -- isn't this slow...? Link to this post

    Long story short: a new site was developed in SilverStripe and we wanted to test how well our site was doing as far as response times. We've been experiencing some sluggish response just by browsing, so we tried to run Apache's benchmarking for one location to the server (not geographically close). Here are the results of that test:

    C:\Program Files\Apache Software Foundation\Apache2.2\bin>ab -n 1000 -c 5 http://******************/
    This is ApacheBench, Version 2.3 <$Revision: 655654 $>

    ------

    Somehow, these results seem to be a tad sluggish. I would love to hear advice or opinions from anyone! Please feel free to let me know what you think. Is this slow?

    Oh, and we're running 4GB RAM, Apache 2, php w/ APC.

    I'm looking forward to your responses!

    Thanks,
    N
