What's the Best Way to Secure an SMB Server Without Sacrificing Performance? or Why Is My SMB Server

If your SMB server is dragging, look at the disk I/O. Run `iostat` (Linux) or `perfmon` (Windows) to see if the disks are maxed out.

Too many users? Maybe. SMB isn’t great at handling tons of concurrent connections. Try limiting max connections or splitting shares across multiple servers.

And yeah, SMBv1 is a dinosaur. Upgrade to v3 and enable SMB Direct if you have RDMA-capable NICs. Game-changer.
