I found some reference that discuss about LVM1 volume with snapshot performance https://www.redhat.com/archives/linux-lvm/2003-January/msg00173.html https://www.redhat.com/archives/linux-lvm/2003-January/msg00239.html and I follow the steps with my LVM2 command "sync ; time dd if=/dev/zero of=filename bs=1024k count=2000" the result is dd write on LV without snapshots = 150MB/s dd write on LV with 1 snapshots = 4.42 MB/s I got very slow write performace. but read has no problem. is this result work as expected?
