Has anyone else found differences in upload times, between FTP and the management interface? These are times of single file uploads, from my local file system:. (no bandwith issues) A tiff file of 4.7 MB: From the MI: 2'10" / Using FTP:25 seconds A jpeg of 478Kb: MI: 14 seconds / FTP: 3 1/2 seconds An mp3 of 3.6MB: MI: 1'40" / FTP: 17 seconds Why is this happening? Times were measured from pushing the required button until the page response (in the case of the MI), and until the "transfer complete" message in FTP. The test box was a Pentium 200 running W2K, Zope 2.5b4, IE 5.5, and WS_FTP95. Moreover, when using Netscape 4.75 the times were even longer, unless playing around with the browser window (meaning resizing it several times during the upload) wich "speeds up" the upload by apparently compelling the page to respond. (It looks more like a Netscape's bug this sort of response laziness) . Nonetheless FTP was still faster, and doing the same trick in IE didn't change the times above. Is it known that FTP is faster even for single uploads? If so, why does it have to be that way? Thanks in advance, Ausum p.s. This is a repost. Thanks Oliver for your immediate response. Nonetheless, it looks like there might be more that explains such a big difference.
