“I regularly run and post various benchmarks comparing POHMELFS, NFS, XFS and Ext4, [the] main goal of POHMELFS at this stage is to be essentially as fast as [the] underlying local filesystem. And it is…” explained Evgeniy Polyakov, suggesting that the POHMELFS networking filesystem performs 10% to 300% faster than NFS, depending on the file operation.

Matthew Dillon posted on update on his evolving HAMMER filesystem, noting that it “passes all standard filesystem stress tests and buildworld will run with a HAMMER /usr/obj”. He also noted, “pruning and reblocking code is in and partially tested, but now needs more stringent testing; full historical access appears to be working but needs testing.” He added, “there are two big-ticket and several little-ticket items left. HAMMER will officially go Alpha when the big-ticket items are done, and beta when we get a few of the little-ticket items done.” The two “big-ticket” items left to be completed are UNDO crash recovery code, and handling for full filesystems.

“HAMMER won’t be ready for sure (things take however long they take), but the hardest part is working and stable and I’m just down to garbage collection and crash recovery,” noted Matthew Dillon, discussing the status of what is ultimately intended to be a highly available clustering filesystem.
