For the file storage or for the shmlog?
When do you start nuking/expiring from disk? I suspect the load goes
up when you run out of storage space?

Has anyone experienced very high server load averages? We're running
varnish on a dual core with 8gb of ram. It runs okay for a day or
two and then I start seeing load averages in 6-10 range for an hour
or so, drops down to 2-3, then goes back up.
This starts to happen once we have more items in the cache than our
physical memory. Maybe increasing our lru_interval will help? It's
currently set to 3600.
Right now we're running with a 50gb file storage option. There are
270k objects in the cache, 70gb virtual memory, 6.2gb of res memory
used, 11gb of data on disk in the file storage. We have a 98% hit
ratio.
We followed Artur's advice about setting a tmpfs and creating an
ext2 partition for our file storage.
I also tried running with malloc as our storage type, but I had to
set it at a little less than half of our physical ram in order for
it to work well after the cache got full. I don't understand why the
virtual memory is double when I am running in malloc mode. I was
running it with 5gb and the virtual memory was about 10-12gb and
once it got full it started using the swap memory.
Thanks for any help/insight.
best,
