asset? server load? just static

hi everyone

I am new to ci, but experienced in coding and php .

I saw the asset concept and really liked it. It makes life very easy when it comes to managing multiple js and css.

I got one concern here:
asset loading goes thru ci and it puts a extra load on the server. this extra load is not due to original request to the server, but due to the second request to fetch the css or js file. but these files can be simply fetch directly with no php involvement.

is it a concern to worry about this little extra load? are there any other solution other than asset manager classes?

is there any asset manager class that would simply give out the static url of the files?
