A question about differences in performance between Mac and Windows

[jbv at souslelogo.com]

Hi list

I have a standalone used as a frontal for requests to a DB. The results
are compressed and base64encoded by a LC script on the server, and the
standalone displays them in a table field after base64decode and
decompress.
On Mac, the process takes 0.25 second to 1 second (when the amount of data
is important).
On Windows 7, it takes at least 3 to 4 secs, no matter how much data.

Is there any rational explanation for that, and possibly a way to speed up
things on Windows ?
My guess is that some system librairies are called for base64decode and
decompress, which are significantly slower on Windows...

Thanks
