Thanks for the amazing response time.
I thought that was the case, based on the screen shots on the ww.wp.xz.cn plugin page. I knew my site has a fair amount of content, but it isn’t all that busy, I wasn’t sure how much content (including woocommerce) had on cache size vs traffic. Although I did install the plugin just prior to our monthly newsletter going out, which is generally a busy time for the site.
