Do you know if it is possible to reduce the number of php files that make one's template work, concatenate them, in order to reduce the number of server hits ?
For instance have index.php and sidebar.php merged into one ?
Or have header.php and footer.php not as an independant files, but being a part of index.php ?
Technically, I suppose I could replace a require() with the simple php code for the footer/header/sidebar, but I have no idea if it would work, or if it would cause problems.
I'd be grateful if you can give me your opinion :)
In case you wonder why I'm asking that weird question, here's the explanation.
I have a blog with many visitors (almost 35k unique visitors per day for 135k pages seen), hosted on a mutualized host. For 8$/month that host is extraordinary I think, no downtimes, no issues, very fast for both the database and the files, even with 35 000 visitors per day. For a server holding such traffic on a wordpress platform, most usually I should be paying much more. But there's one limitation, one, that is horribly annoying : the server counts the number of hits your website generates, and it is limited to 400k hits per day.
I'm already hosting all non-core files (even the smileys) elsewhere, but I still make 10 hits per unique visitor. If I can concatenate my template files, I could avoid a minimum of 3 hits per visitor, which would be enough to sustain more traffic growth in the future.
That's for the reason behind my question :)
