So I recently upgraded my net to 2.5GbE, and I could achieve 2.5Gbps speeds via iperf and using FTP transfers to my nvme cache backed share. But under NFS/SMB I can only max out around 92MB/s. I tried adding the following to SMB conf, not luck so far, am I missing something obvious? server multi channel support = yes server min protocol = SMB3_11 client min protocol = SMB3_11 tower-diagnostics-20220810-2217.zip

Thx @Squid shinobi container is a root cause here, stopping it solves the problem, I'll try to dig around how can I make it more stable probably in a separate thread

I'll try today, thx

Hi folks, I'm experiencing a really annoying issue with my server, every morning my server becomes unresponsive, physical login to machine fails with "fork resource unavailable" message. I need to hard reset my server to make it operate for another day. Below a snippet from logs showing "blacklisted device" errors before forking problem? I have plus license purchased for this stick.

After very long debugging session, recreating the whole unraid server from scratch, a reboot of client machines (PC and iMac) helped, go figure ...

I tried from my wife's iMac, it only has 1 gig NIC, and i'm also seeing ~300-500 Mbps upload speed from there. To eliminate my PC (and switch), I ran iperf tests between my PC and my router, although router's NIC is only 1 gig I could saturate this connection both ways. This is super strange, as just days ago I saw ~1.3 Gbps (140-150 MB/s) transfers from my PC to unraid on my initial data migration. (I'm testing transfer speeds with iperf3 and ~4GB windows/linux ISO files to ignore small files impact) Also some forum digging suggested to turn of NIC offloading from Tips and Tricks, this had no impact, I also tried Fix common errors plugin, no luck there too.

Hey folks, I'm running unraid 6.9.2 on my previous ITX PC, it has 2.5 GbE NIC connected via 10GbE switch to my PC which also has 2.5 GbE NIC, now iperf3 from unriad to my PC saturate 2.5 Gig connection without issues on just 1 iperf stream. But iperf3 upload from my PC to unraid is floating around 500-300 Mbps on a single iperf stream, if I run multiple iperf streams with say -P 8 I can saturate 2.5 Gig link. Any suggestions where I should look for problems? Initially when I first setup this server a couple days ago I was transferring data to my (non cache backed) array (2x 4TB disks) I saw ~1.3 Gbps direct to array speeds, since initial setup I just added 3 docker containers: Portainer, html speed test and unifi controller (connected to br0 custom with it's own IP). Stopping docker service has no impact. Server specs: Ryzen 5 2400g, 32GB RAM, 2x 4TB HDD in array, 1x 500GB NVME - unused atm, 1x 160GB SSD unused atm BTW transfers to NVME or SSD shares show same behaviour 1 stream is limited to ~300-500 Mbps
