I did a copy/paste from the site and I opened up the JS file in my browser and did a save-as and both times it was about 314k on disk. It looks like your server has GZIP, and thats why it's appearing as 76k.
It's 76k of transfer, but deflated from GZIP it's about 314k: screenshot from YSlow: http://twitpic.com/ls90/full On my server using the files and sizes specified above with GZIP are as follows: ------------------Normal----------GZIP --------------------------------------------- jQuery:.........55k.............16k jQuery.UI:.....63k.............25k Cluetip:.........29k.............6k NyroModal:...27k.............9k --------------------------------------------- Total:...........180k ...........56k So, 76k vs 56k isn't that bad, I'll probably use the combined file just for simplicity and less files to download - and I just realized your file is slightly larger because there's a few UI components I left out. I'll try and build it the way I need it and use that Is the minify script you linked to avalible for use on a website? I ask because we're running ASP.NET here and I don't think it's a good idea to install PHP along side that.
