<strong>Apache</strong> <strong>HTTP</strong><br />

<strong>Server</strong> <strong>2.4</strong><br />

<strong>Problem</strong><br />

<strong>Diagnosis</strong><br />

Jeff Trawick<br />

Introduction<br />

What kinds of<br />

issues<br />

encountered<br />

Using tools<br />

inside the web<br />

server<br />

Looking from<br />

the outside<br />

What if you<br />

build the code<br />

differently<br />

Adding symbols, not stripping executable<br />

Disabling in-lining of functions for better diagnosablity<br />

Disabling other optimization so that more variables can be<br />

checked<br />

(huge YMMV)<br />

Compare with<br />

httpd 2.2 and<br />

nginx<br />
