This great little add-on is perfect for a little piece of mind. On my site it runs through 145 pages in about a minute and a half. So, I find one thing I need to change on the site and there's no time for maintenance mode. I edit, clear the cache, then run this utility. I now have piece of mind that all visitors are seeing the most current pages and with no need to wait forever for C5 to cache itself. The ability to have late night cron jobs as well are a extra nice + to the above stuff.
Buy this now while it's cheap.

I added Cache Warmer and GTmetrix doesn't lie.

No more waiting for users to access a page before it's cached. This beauty creates the cache files all at once and delivers a smoother, faster user experience. I do suggest utilizing Cron for this add-on to ensure successful up-to-date caching.

Nice work!
