Reason for asking is, as surfing (for a freeware graphic editor that’s clean and simple) noticing, Pollish version, French version, Japanese version etc of very similar programs……so along with those, people search keywords repeatedly, so raising your profiling on Goggles ranking (well how it appears to work anyways)…

So if that is the case by adding all languages files we have for Xoops, into our system..... That will make the site rank any where in the world and since Google is global, so increase ranking overall?

What do you think to the idea?

In the standard XOOPS install, the language files are merely sitting on the disk, so they shouldn't take any additional resources other than disk space.

I don't know how the various multi-language hacks work; maybe they use additional resources.

yes they do.
atleast emlh increase cpu loading about 30%:
