FreeNAS-11.3-U3.2
Model:
Intel(R) Xeon(R) CPU E3-1220 v6 @ 3.00GHz
Asus p10s-v
Physical Memory:
16272 MiB
Disk
wd ST8000VN0022-2 8T x 4 raidz2
I am migrating data from centos to freenas, the efficiency of raidz2 seems to be very slow
I tried nfs mount, using rsync transmission at the beginning, the transmission speed will be 30m/s, but when the memory is exhausted, the speed drops to 10m/s and continues at this speed
I removed my disk from centos and placed it in freenas to use the disk import function. The average transmission is also about 10m/s.
How should I find the problem?
