System Calls In Apache (Linux) vs IIS (Windows)

The following 2 pictures show a clear difference in system calls between a Linux' Apache, and a Windows' IIS. Draw your own conclusions. :-)

First up: Apache.

Followed by: IIS

They both seem chaotic, but the Apache one shows a lot more structure than the IIS one, which seems to be tangled up in its own web.

    well maybe this is the raeson why the IIS were so vulnerable back in the day as i guess that these systemcalls back there remained the same as now

    As G-WAN outperforms Apache and IIS by orders of magnitude in performances (for both static and dynamic contents) and footprint (the 100 KB G-WAN is a *native* Web App. Server offering full ANSI C scripts) it would be interesting to see the same graph applied to G-WAN.

    G-WAN is available on Linux and Windows (where it beats IIS-7.0-nested-in-the-Windows-kernel).
