I have been using AmazonFeed and love the plugins functionality and caching. However, there is one major drawback which I have not been able to get over and have been forced to disable it.
Basically, when I post a new article on my site, the CPU goes nuts, spikes way up and the server crashes. In testing my system over the last two weeks, I have isolated AmazonFeed as one of the problem plugins creating this phenomenon (SEO Smart Links and YARPP are two others).
I am a bit stumped as to what is happening here. My site uses Hyper-Cache and has 1800 posts and about 180 tags and 12 categories.
Any help is greatly appreciated.
