I have this weird performance issue. Two servers in a cluster, one on Windows 2012 R2 other on Red Hat. The Linux server works great, but Windows has issues. Detaching a file or using SmartUpgrade ( via attached file) starts OK but then gets slower and slower, and in the end really only moving single bytes… A SmartUpgrade may take a 1-2min. from Linux server and 5 hours from Windows server. I am quit baffled, investigated “everything” . The only Notes.ini setting that makes me stop and wonder, is TCP : for Windows it is TCPIP=TCP,0,15,0,45088, and Linux it is TCPIP=TCP, 0, 15, 0,32800 (we use encryption and compression)
Subject: virus scan?
Do you have virus scan product on the windows server? Try disabling the scanning for a test.

Are there tcp ip setting that are incorrect on the server?
Are there network issues to the server?

Subject: No virus scanner on server…but
