I have read the option description and have been through this thread a few times but some of the conversations about it are a bit confusing. This is one of the better outlines of the behavior that I found: There wasn't much confirmation that this was the correct understanding of "synchronize" works.

I think I've got things understood here with the synchronization setting. Would anyone mind double checking my understanding? I'm effectively trying to create a Least Recently Used cache for my array. Where the most recent files (by the date they are written to the server) are kept in cache and are written to the array for parity protection. The goal is to avoid spinning up array disks unless: parity is being checked the user would like to access a very old file. I believe this is what's happening with the "Synchronize Primary files to Secondary" setting. I've made a visual for this below going through 5 sequential steps.

No, sorry for the confusion. That was Server array to Client SSD (windows PC).

This latest one was from the array (4x7200rpm HDDs), to a local NVME SSD.

Anything I can do to improve reliability? I'm back down in the 80s again. Iperf looks the same, changed nothing in windows.

For some reason it will hit 250MB now... other than stopping the array, and turning SMB MC off to try this transfer, nothing changed. I tried turning Multichannel back on and retrying and it still hit 250MB/s but only 250MB/s. Is SMB just this flakey?

No, my PC has two 2.5GbE ports. But I can't get anywhere near 2.5gb speed let alone any SMB multichanneling speeds.

Thanks, I edited my prior post with the results. Still getting 2.5g from both interfaces.

I believe eth1 🤔, I can re-run it to confirm from both. I assume just down one port at a time, run the test, then switch ports which ports are up? EDIT: I'm getting 2.4Gbits from eth0 and eth1. For some reason my monitors 2.5GbE is quite slow, less than 1Gbit. But that's another issue for another time. For now I can disable that and work on just the question of getting to 2.5GbE speeds out of the server.

I've tried following prior posts, swapping cables, going directly to my server over ethernet...nothing works. I cannot get faster than 1GbE speeds. Server (Qnap TS-462): - 2.5 GbE onboard - Mellanox 10gb SFP+ DAC (installed drivers) Network Switch: 4x 2.5GbE 2x 10G SFP+ DAC PC: - Intel 226 2.5GbE on board - Realtek 2.5GbE in Dell USB hub monitor I can confirm in iPerf that both my PC's connections are hitting expected speeds, and i've enabled all SMB multi-channel settings...but I can't even get 225MB/s reads off the array. I usually can't even get 1GbE speeds (100-125MB/s). Kind of stuck here: tower-diagnostics-20241012-1808.zip
