Just FYI:
So I booted 2.5.40 with the raid0 fix on our usenet news peering server yesterday. It is a box that exchanges binary feeds with about 40 peers, 400 GB/day in, 600 GB/day out.
It's a dual PIII/450, 1 GB RAM, 4x18 GB article spool directly on partitions (not raw, but normal partitions). INN-2.4/CNFS.
With 2.4.19, it runs fine. With 2.5.40, it goes wildly into swap. I'm assuming the I/O is pushing the newsserver binaries and database mappings into swap.
# free total used free shared buffers cached Mem: 1033308 1027316 5992 0 836884 29776 -/+ buffers/cache: 160656 872652 Swap: 976888 364032 612856
No need to swap 364 MB when there's 872 MB still free... This makes the machine dogslow. An 'expire' process that runs every night normally takes 15 minutes to finish now has been running for 10 hours and its still not finished.
Article acceptance rate has halved, the machine can't keep up with the binaries it is fed.
I'm going to risk corrupting the databases and reboot back to 2.4.19 now.
Mike.
