With the new path_alias handling, it seems that the biggest gain is in cutting the volume of sql queries.<br><br>The stuff I did in 4.6 was (again) very specific and based on the settings I used for Pathauto.<br><br>Perhaps we could write an advanced 
path.module settings page that lets site admins turn of alias lookups for specific path types -- where a path type is defined, essentially, by arg(0).&nbsp; I can think of the following paths that might qualify:<br><br>- node<br>
- comment<br>- admin<br>- taxonomy<br>- user<br>- blog<br><br>This wouldn't require regex lookups on-the-fly, and would be turned off by default.&nbsp; But it might allow me to say: only do the following path lookups.<br><br>The gain is minor on small sites, but not large ones.
<br><br>Drawback (and there may be more): Might need a module hook to let module 'register' themselves with path.module's settings.<br><br>-Ken Rickard<br>agentrickard<br>
