I sent this in to our host, I've done everything I can to improve upload time, this is on them.
Considering the inconsistency in loading times, there is nothing I can do about that... its up to the host to provide a consistent server, if they can do that, I can do my part and make it a bit faster by installing automatic cache refreshers, altering code, speed boosters (as I like to call them), etc.. etc.. But with inconsistency, its hard to notice MY work, which pisses me off because I've worked my ass off.
Last time they told me I'd have to pay an extra $2 per month, if they tell me that again they can go shove it up their ass. I'm not paying my hard earned money to REWARD them with inconsistency.
