The difference perhaps between local speed and HG may be whom owns the 
Apache daemon at the time the script is running. Guessing your local 
server is running as root user and HG has properly configured Apache for 
you as just a user. Permissions are also likely to be the answer also 
for needing a temp file.

What kind of file is being resized? By chance an image file, is there an 
improvement using ImageMagick?
