Cygwin does a lot of magic, some of it depends on obscure things like your CYGWIN environmental variable. Perhaps you should all confer and compare your cygwin setups? ------------------------------------------------------------------------ [2002-07-21 04:51:33] gallery@bianco.net Win32 - Full netpbm dist runs at acceptable speed. Was able to fix problem by swithing to full netpbm release (10.5). I only experience the idle CPU problem with the netpbm-gallery 1.1 release, distributed on the gallery site. So it may not be a PHP exec() bug after all. In order to use the full netpbm dist, I needed to make changes to Gallery's config.php: Change: $gallery->app->pnmtojpeg = "ppmtojpeg"; To: $gallery->app->pnmtojpeg = "pnmtojpeg"; ppmtojpeg.exe does not exist in netpbm 10.5.

I had him zip up his installion so I could see if this worked for me. It did not - I still have the same issue as everyone else.

Each 1.2 MB image takes about five minutes to have a thumb and resized version created. At first I thought it was due to the celeron, but after watching TaskMan, the netpbm exe's are idle most of the time.. they take available CPU once every few minutes.. Something is causing a wait/timeout in the process. I am not behind a firewall, so Im not sure that is the issue. It is possible that using the netpbm/gallery microdist is causing the slowness. I have been unable to get the standard netpbm dist working.
