Clean (pretty) URLS create slower load times?

[skim1114]

Will using clean urls create a slowing loading website? I've noticed some lag...but that could be due to other things. I just wanted to see if this is something others are experiencing.

Thanks

I always use pretty (rewrited) urls, so I don't have any comparison. Nevertheless, any delay is probably not caused by the CMSMS code, but at the webservers'.
To take Apache as an example:
- If you turn on the Rewrite engine it not only rewrites, but also checks if the url is valid non-rewrited.
- When the mod_rewrite module is loaded, it uses more memory; so less cache space available.
- If you allow .htaccess files in the site's root-dir, it has to scan al the dirlevels up for other (parent) .htaccess files.

So what you are saying...is that it can take a little more time.

also... with pretty urls enabled, the php code has to dectect that, and try to generate pretty urls whenever links are created.

So yes.... pretty urls will be a bit slower than otherwise simply because there's more logic in place.
