UFS1 vs UFS2

OpenBSD by default use UFS1 for partitions smaller than 1TB. FreeBSD use always UFS2. UFS2 uses double the amount of space for inodes. basic operation seems the same. Does it make sense to use UFS1 for small filesystem (on SSD) that would have few millions of files. It will take less space

Before about 3 months ago or so, fusefs-kmod worked fine under FreeBSD 9. Now, with newest 9 it doesn't on amd64. It works fine on i386. on amd64 i can do ntfsmount but the mountpoint is not a directory and all i can do is to unmount. tried exactly the same version of fusefs-kmod, as well as

How do your tests work? Do you examine PTEs directly to check for superpages or are you relying on the vm.pmap.pde sysctls? the later. anyway - algorithm described on list - that heuristics detects consecutive page access doesn't really help the urgent case - RANDOM access to large amount
