    Hi,

    I have a fresh install of ISPConfig 3 and a small landing page with a Vimeo video. When we stresstest this site with more than 500 users the CPU load is going to the roof.

    We have 10 cores and everyone is pushing 90%.
    We have 16GB RAM, but only use 3GB.

    Everything is running on Ubuntu with an Apache2.

    Any ideas?

    What kind of stresstest? Maybe it generates so much load that high CPU load is to be expected.
