Well if the objects itself are the source of the lag, I don't see this doing anything, all it does is load (and also unload, etc) a set of objects from a database.

I am also working on a PHP script that won't require you to import via the filterscript. But yes as for your original question simply replace it with ImportObject(make sure it's in OnFilterScriptInit), run the server and load the filterscript once.
