I don’t agree with this post and here’s why (i couldn’t comment on his blog because he doesn’t have comments):
IMHO that’s not entirely correct.
I’m sure that if you’re not packing stuff but just removing comments and whitespace you’ll get completely different results.
The guy is just looking at 1 aspect or 1 reason which gives a distorted image.
Anyway my experience tells me that removing whitespace and comments in a production environment and then have them sent compressed by the webserver to the client gives me the best results. Regardless of this guys 1x test setup with 1 machine.
