That's the price you pay for the smaller file size. Depending on the connection speed it may be faster to use the compressed version.
When you minify you get a smaller file size than the original but not as small as the packed version. You don't incur any execution overhead and probably get a small performance boost because there is less for the JavaScript interpreter to parse. If your server (and the browser) supports compression you can get even better performance because the decompression is performed by the browser, not the JavaScript interpreter. After the packed version's initial hit at startup, packed and minified versions should perform the same. Aaron
