This thread covers a recent quest to improve my server performance. Lot of posts relate to performance tuning multiuser and buddypress installs. I've been at this for three long days and want to record this for myself, and hopefully my lost sleep is of some service to others.
First Rule... GoDaddy is Slow Daddy; server up-time is an issue often enough to be noticeable. I use mon.itor.us and they have a history of network outages, and terrible delays servers often unreliable to 1/2 day at a time.
I've been a Godaddy customer for over 6 years and would really like to work with them. I asked their d support how to improve site performance - they offered a couple of service levels above their grid level - but I fell over when they said I'd have to fully re-install all of my content and that I couldn't internally transfer data between their servers. That was a bad-service show-stopper for me. Their servers appear are very over-loaded so database activity takes a long time, almost regardless of what else you do.
Caching only helps after you get to your server - and this is taking between up to 8 seconds just to reach the server -- So there's no way to fix GoDaddy. More about W3 Total Cache versus WP Super Cache later.
I did get a server to work speedy on Godaddy... Oops- I take that back. Check out the over 5 seconds for Godaddy decide to serve my home page. See eFlyer.cc report. Image serving is way slow too.
When I investigated hostgator - they said they were faster. Really? I'd sure like to see it for myself?
When I searched for multipress/buddypress blogs I came up blank. Finally I ran a performance profile on their blog, below, and aside from sluggish CDN (Content Delivery Network) stuff, they appeared faster - at least at hosting their own blog. There wasn't a 6 second delay for the home page at least.
Their blog appears to be wordpress - based on Page Speed & YSlow Scores (now I don't feel so bad).
The big deal for them is the free migration included with the business account. It doesn't cost much to see if they are able to deliver.
But I wanted more. I searched in vain to find a multi-site hosted on hostgator to benchmark. No luck. I'll probably migrate because I sure can't stay with Slow-Daddy.
I'm going to put the W3 Total Cache versus WP Super Cache in another post...
