Serious slowness issues with W3 Total Cache

    I recently upgraded to 4.0, but these issues were happening prior.

    I’m on Linode and definitely have enough resources for all the sites I’m running via Plesk.

    On my Netmix.co multisite network, which includes Netmix.com, one of my most important sites, I have Total Cache installed. I tried every type of configuration, some with Opcode enabled then some with disk enabled. I’ve turned on and off database caching. All kinds of slowness problems ensued.

    I used auto minify. I used manual. I used browser caching. Everything and then the minimum and I just can’t get this to work the way it should.

    I’m running NGINX with Varnish on Linode with Amazon Cloudfront as a CDN. When I turn off Total Cache, my site loads very quickly. When I turn it on, it’s as slow as molasses. Down to 25 seconds according to Google Page Speed Insights.

    Every since I turned this on, it’s been killing my Google Page Rank, because people are bailing since it’s been loading so slow. I thought it was server related, but once I turned it off…zoom, everything got that much faster.

    I need to keep it off until I figure out what the issue is. I’ve been reading a ton of tutorials on using NGINX and Total Cache and you’re supposed to configure a separate conf file with all kind of rules, but the sys admin I’ve been working with says I don’t have to do that and that the .conf file I have for .nginx – the basic .conf should be fine.

    I have no idea what to do and am so depressed about this killing my traffic and opportunity. I hope someone can help. I see Total Cache offers support for $200, but I’d like to try and figure this out myself.

    Well, I had to turn it back on, because now the server is delivering a “Forbidden” message intermittently.

    This is just a very frustrating at the moment.

    I found out that Total Cache was causing a constant spike in MySQL CPU usage, so I removed the plugin for now until the plugin developer resolves this issue. This problem completely killed my SEO and Google Rank over the last month while I fought with trying to figure out how to resolve why it was so slow on my server. It was causing my site to load in 28 seconds and it’s become a HUGE problem. I am so very upset with this situation and removed this disaster before it put me out of business.

    This may be unrelated but I had a very similar problem which was solved by switching from using APC for Page Cache etc to Disk Enhanced. Load times went from over 20 seconds to less than 3. I assume it was some problem with the server set up.
