Having played with several web servers online, I've seen things such as goDaddy not enabling gzip by default. Same with a few IIS drops, default installs of apache, and so forth.
I keep running across servers that don't have basic things that improve your website speed turned on by default.
This leads me to two options: everyone who makes webserves packages it poorly, or I just don't understand why they've done this. It's much more likely that I don't know why they don't do this.
Could someone enlighten me as to why you would ship webservers with disabled features such as gzip, and various cache control headers?
I thought faster websites were a result of this, as per what ySlow and PageSpeed tell me all the time. What are the drawbacks?
