Well, I set Expiry Time to 3600s and Garbage Collection to 10 minutes. I have currently 3667 cached pages in WP-Cache and 2464 cached pages in WP-Super-Cache.
However it seems like that when it “collects garbage” once in 10 miuntes, it uses a lot of resources: http://i44.tinypic.com/33boncn.png
And I even cache it directly into the RAM instead of HDD.
Hi!
I have the same problem. Every 10 minutes server load go from 0.3 to 30 because of I/O wait on HDD!
I have the S.O. Lustre…
HELP!!!!
What kind of server are you running on? It’s not possible to avoid the I/O but it’s never that bad usually. Set the expiry time to 5 or 15 minutes and garbage collection to 10 minutes. Does that help?

CPU: Intel Quad-Core Xeon X3220, 2.40 GHZ
RAM: 4x 2GB Kingston ECC Not-Registred 667Mhz
HDD: 2x 150GB RaptorX – 10k RPM, raid 1
Just set the expiry time to 5 minutes, garbage collection to 10. I’ll let you know tomorrow how it performs.
Btw, it’s the Super Cache doing it. When I had only legacy WP-Cache caching enabled, it worked fine.

Tried both 5 and 15 minutes, looks better with 5 minutes:

As you can see in my previous entry, it’s better. But there’s been plenty of new versions released lately, so maybe something is improved. Dunno yet.

Hm, actually when I tried it now with WP Cache and Super Cache enabled (Fully on), it caused so high load, that the server was inaccessible for a moment.
So I stick with Super Cache Disabled, only legacy WP-Cache caching (Half on) and it’s fine. Expiry time on 300s, still have around 2000 files cached anyway.
But it works fine and I made a new record 2 days ago. 860k pageviews ^^
