RE: Performance issues with File shares

OS400 V7R3
Windows 10 with latest updates
SMB1 is disabled on both systems

Network & firewall changes absolutely.
New firewalls - no.
Router - no.

I'm actually on the same switch as the IBMi

1. What OS version are you running on the iSeries?
2. SMB 2 vs SMB 1. Make your you enable SMB 2 on your iSeries
3. Disable SMB 1 from your Windows 10 system if enabled.

Any network changes? New firewalls / Router in the mix?

We recently had to rebuild our network servers and workstations from scratch (New Windows 10 installs, new server installs, etc.).
If you're wondering why... your first guess is correct.

The IBM i was not touched.

Now that things are back to the new normal, accessing files on the Netserver shares is painfully slow. Even small text files. Opening Excel files is ridiculous.
Navigating and traversing the directory structure is fine.

We have added a second endpoint protection software.

I remember many years ago, I had to do something in Windows 7 to speed things up. My access prior to this reinstall was nearly as fast as a Windows network share.

Any ideas?
