Hi,
I got a AMD-Fileserver with enough CPU-Power and 16GB RAM.
My HDD are some 3TB, 2TB and 1.5TB in mergerfs and snapraid. Everything works fine, but the speed over 1Gbit-LAN was too slow for me. Now I installed a 10GBe and first tested it with MTU=1500. iperf says somethin about 9Gbit/s what is pretty nice, but the Filetransfer between my two server (the other one is a Opteron 3280 with Proxmox and ZFS-RAIDZ1--> fast enough) is not really faster than 1Gbit (120MB/s max; 85MB/s average).
I think the problem is mergerfs, because every disk is read/write on its own.
Is there any chance of improving of mergerfs-speed? SSD-Cache or something like that? ZFS/BTRFS/RAID6 on my OMV-Server is not a real option because it doesn't support ECC and I'm using different disk sizes.
Any ideas?
