"We have the full page cache. That worked great, but sometimes customers would get a slow page because the page was not yet in the cache. The crawler solved this problem by ensuring pages are always in the cache. It is very easy to use. Set it and forget it. Its the way extensions should be."
"I tried 4-5 FPC extensions. MGT, Lesty, Varnish, Turpentine and etc. but Extendware FPC is amazing. You can configure and install it very easy and fast. I recommend to use FPC with Site Optimizer and Web Crawler.
Support is great and very friendly. "
