Wordpress Faster caching method?

So your using this on Live Website?
How much traffic did you got?
I manage two large WP site.
3K and 5K users per seconds based on Google Analytics and WP Super Cache works great.

I'm not doing this because I get tons of traffic, it's because I enjoy tweaking things and learning. There is a side benefit that using a faster caching method will have a lower "time-to-first-byte" which improves SEO, but that's mostly a byproduct. I cannot rationally justify spending this much time on it for purely traffic reasons--I just like doing it.

 

Since ffpc loads things into RAM, wouldn't that mean the server would need much more RAM than with WP Super Cache's method?

For example, I'm currently on a 2 GB RAM VPS with Vultr. I'm running a WordPress multisite with 12 subsites (one of them with a really active bbPress forum), plus a few more single-site WP installations. This all runs beautifully with WP Super Cache and I'm only paying $15 per month. It seems like I would have to get more RAM to use a slightly faster method like ffpc.

 

That's an excellent point Daniel. Since all the content is text, it doesn't take up much space--the media files are still stored on disk. I suspect most of your sites are like mine with only a few hundred posts at most, and for those, I'd guess that 30-40 MB per site would cover it. But if you're running huge blogs or a ton of small blogs, then yeah, you'll start to run out of room. I recently worked on a blog that had 20K posts, and the posts database was <200 MB, so I'd guess the generated html that gets cached in memcache wouldn't be more than 2x-3x that depending on the Wordpress theme they're using.

 

Yeah. I'm running a podcast network. One of the sites has a massive bbPress forum.

For now, I'll stick to WP Super Cache as it's easy and working well without needing a lot of RAM.
