WebIf there is insufficient memory for the DDT to be cached in memory, each cache miss will require reading a random block from disk, resulting in poor performance. For example, if operating on a single 7200RPM drive that can do 100 io/s, uncached DDT reads would limit overall write throughput to 100 blocks per second, or 400KB/s with 4KB blocks.

WebFeb 3, 2024 · ZFS performance can often best be described as "pig-like". All you can do is throw a lot of hardware at it and then try to tune it to make it "not-as-slow-as-it-is-by-default". ZFS is a lot of great things but "fast" has never been one of them. WebFeb 11, 2024 · NVME is nominally rated for up to 2400 MB/s but best I can get is aroung 800 MB/s but that is clearly due to power of my laptop, and I am ok with that speed. However, when I copy (using file explorer) a lot of small files, speed drops dramatically to 30 MB/s. Again I know this is crappy windows copy performance. side load horse trailers for sale

WebFeb 9, 2024 · There are two aspects of this. First, there are obvious areas of ZFS performance where it was limited by IOPS and bandwidth, such as deduplication and RAIDZ read speeds. Modern NVMe drives have very high values for both, high enough to absorb a lot of reads, and even SATA and SAS SSDs may be fast enough for many purposes. side load google app on to fire
