Hello, I've made a post few weeks ago - https://www.reddit.com/r/sysadmin/comments/ikihzj/bad_performance_of_software_after_upgrading_from/ but the issue still exists.
Long story short: After updating desktops to win 10 a software which communicates with the NTFS storage(clustered share)started performing really slow(the PCs are with okay hardware), nothing else was change on the server storage or network. A lot of things were tried in the process of troubleshooting the client - updating drivers, fresh install of win 10, reinstalling the software, messing with the registry, trying other versions of SMB, etc.
As I monitor with task manager and Wireshark during the freeze I've noticed few things:
- - this process repeats https://imgur.com/a/OqjAhPF and "SIME2020" is 1.5 megabytes from number 12848 to 174404
- - The adapter speed is 1Gb and we need 100Mbps for a good connection https://imgur.com/a/9trsnNN
- Is it normal to have that much malformed packets? https://imgur.com/a/OIqZ4z6
- After a refresh i noticed this one on the DC https://imgur.com/a/5WpZuBd
Any tips or ideas for resolving this issue or troubleshooting it will be strongly appreciated, thanks!
