Well I have finally set aside some time to try and test performance using the zfs kernel module that I blogged about<\/a> a bit ago.<\/p>\n

Overall the zfs kernel module produced results that were similar to the ones I saw while using ext4, however most real world zfs setups are not limited to a single disk, so it will be very interesting to see what kind of performance numbers we will see when we start benchmarking on setups that have many disks.<\/p>\n

Although the zfs results were slower in almost every single case, ext4 was not too much faster in most of those cases and I suspect that there are lots of people out there who would be more then willing to take a tiny hit in speed, in order to gain the substantial benefits<\/a> that comes with having zfs as your underlying filesystem.<\/p>\n

Here are some of the benchmarks I got doing the following:<\/p>\n

a)create 10,000 files using touch
\nb)create 10,000 directories using mkdir
\nc)untar the latest stable linux kernel
\nd)create a 1GB file using dd
\ne)find 10,000 files
\nf)delete 10,000 files
\ng)find 10,000 directories
\nh)delete 10,000 directories<\/p>\n

At some point soon I plan to add values for raid2z, btrfs, iozone results, etc.<\/p>\n
