I was previously using the Dreamhost PHP compile and it was around 6mb. It did however lack som features I needed so I did my own compile with the install script found on the wiki.
The result is a 20mb php-cgi, instead of the usual 6mb.
Anyone care to explain why and if I can make it smaller? I figured it's more resource heavy to have a 20mb file loading than a 6mb, but I might be wrong (I assume there's some caching etc, but still).
