Not sure if this is a 1and1 hosting issue or a WP issue but as of late I have been experiencing severe load times on my site. Sometimes it averages 20 seconds to load and this weekend it was taking up to 60 seconds to load if at all. However right now it seems fine with 7-9 second load times. The index page is usually around 500k-700k. When I run a load test at http://tools.pingdom.com/fpt/ I notice one interesting bit of info. Plug in http://www.scannerbytes.com and look at the first line of the results. It shows the first item "www.scannerbytes.com" has a much larger green and blue bar (Connect time, first byte loaded and last byte loaded) than all the other objects. Not sure how to decypher that, maybe a host issue?
Here are my plugins (That I have tested with them disabled with not much change in load times):
Add to Any
All in One SEO Pack
Featured Content Gallery
Google XML Sitemaps
Image Upload HTTP Error Fix
KB Advanced RSS Widget
Wordpress Mobile Edition
Wordpress Online Automated Backup
All are up to date.
Do Inactive plugins make a difference?
I have contacted 1and1 and their responses have ranged from "your site loads instantly on our end" to them moving my account to a more stable application pool.
Could use some help to get this figured out as I would assume it frustrates my visitors.
