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.

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.

Do you care about the markup if your comment? You can use the following HTML tags:

<code>command</code>: command highlighting
<pre>text</pre>: pre-formatted code, can be multi-line (black background, white letters)

example <pre> tag
<blockquote>text</blockquote> quoted text
quoted example

None of this is needed of course, I appreciated your comment nonetheless!



  1. 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).
