While uploading thru intranet, the PHP-process uses 99% of CPU, lots of memory (up to twice as much as the file itself) and takes 3/4 hour for 40 MB. While sending this file back using fopen/passthru, it takes a lot time until the browsers download-dialog opens. Then the transfer itself ist very quick !

That's why I guess it is not a http-problem, but a problem in handling files or handling memory ! Another hint on this is, that large files seem to get back corrupt, as testing a large and downloaded file resulted in some crc-errors. On small files all works fine.

This one might be relatet to the bug 10800 (or 10080 %o),
so have a look at that.

Ahhm.... forgot the environment:

Win2kPro, Apache (latest),MySQL,RAID-System for IDE, 128MB of ram and about 40 GB free harddisk. The php.ini was configured for 100mb posts and 100mb files, using 64 MB of memory for each script.

This should be fixed in CVS now. You can try the latest 
development build from but make
sure it's dated after 27th of October 2001.

Also, there are some minor leaks still in the new code.
If you encounter such leaks, please send the shortest
possible code + html with which you can reproduce the leak
to (or me) so we can get rid of these

The fix will be in PHP 4.2.0.
