I have no experience in benchmarking, I also have no real site that I
could benchmark. If someone provides me with instructions and means for
benchmarking I could do some tests.


The PHP documentation for filesize says: 


"Note: The results of this function are cached. See clearstatcache()
for more details.

"
grep shows that clearcache() is not used in drupal, so the cache is
there. But the cache can only help in case you check the same file
multiple times.
The real question is how often you do image_get_info() but are not
interested in file size and is filesize() expensive or not.

image_get_info() return information about image - width, height,
extension, mime type.


It's quite common to get file size (physical size) when getting
dimension.


This simple patch adds file_size to the returned array that contains
file's size in bytes.

+1 for this feature. But we should be carefull with it, though. This
function is called an awful lot. Cvbe, have you got experience with
benchmarking? I am interested to see if this has an impact on speed and
performance.


If so, we could consider a lower level (inside the function) "caching":
just see if the file exists in the file table, if so return those
functions. 


But let's not keep that from including this filesize.
