# Optimizing the Optimization Speed

 * I’m running on my own dedicated server (1.8GHz 4-core Xeon, 16GB ram, Windows
   IIS 7.5) and uploading a single 260k PNG (1018×250) took 25 seconds to process.
   I’m generating 5 thumbnails on each upload. A 248k JPG (800×520) took 12s. When
   I did the bulk optimization earlier it was taking about 15 seconds per image 
   on average.
 * I have everything set to default, just installed your plugin today. I tried disabling
   all image-related plugins as well. Is this normal? Any thoughts on what I can
   do to speed it up? I won’t be able to leave on automatic optimization with that
   kind of delay.
 * With the option to schedule a cron job for optimizing, I didn’t see anything 
   on there for a limit on number of images to process on each run. If there isn’t
   an option/hard coding already in place I think that would be a good feature request.
   I hope that the processing of said image wouldn’t delay the visitor that 15 seconds
   though?
 * Thanks

 * The PNG isn’t surprising, but a 248k JPG should not take that long. On my dev
   box it only takes 2-3 seconds. I don’t do much testing on Windows though, that
   could very well be bottle-necking things.
