Great host, bad plugin

After experiencing the great service A2 Hosting provides, I heard about their plugin and assumed it would be of similar quality. I was using WP Super Cache so I uninstalled that and installed this plugin as well as their W3 Total Cache “optimized” plugin. Using this instead of WP Super Cache, my CPU usage was down slightly but my physical memory usage and IO usage spiked very high, to the point of causing faults on my A2 shared hosting plan. Page load times went significantly higher, on the range of 2-3 times higher. Uninstalled and went back to WP Super Cache. Given the quality of A2 Hosting, this plugin was a huge disappointment.
