TLDR: has anyone ever seen windows explorer slow a transfer because it was trying to update the directory listing (or something similar) after every file transferred?
Today I was moving 21000+ small files for a total of 14gig, half way through the transfer it slowed to below 1MB/s after checking gstat and top (smbd was over 100% again) nothing looked unusual until I got to the ZFS tab. ARC request went up to nearly 7k at the same moment the transfer speed dropped off, assuming it was just another user I left it alone for a while about half an hour later I came back and it was still moving along extremely slowly. Spent another hour going over everything I could think of and came up empty hand, finally gave up and resolved myself to the 9 hours remaining on the transfer which wasn't slowing anything else down and closed the windows explorer window. The moment it closed the transfer jumped to 50MB/s and continued to climb, the zfs graphs also showed an instant drop in ARC_requests, demand and SMBD usage. Windows explorer had the navigation pane up with the directory tree on my FreeNAS showing the destination while the main pane had my local drives displayed, Has anyone seen this happen before?
