Sorry since I am new to this product, please bear with me.

I had the product working properly, and the host it was installed on took a dump. I rebuilt the host and reinstalled the software, and now I only have 1/5th to 1/6th the speed, the device is functioning, I just don't know what the difference in speed is from.

Using this to connect a SAS Quantum tape drive with Backup Exec.

Speeds were near 3000 MB/min, now getting close to only 500 MB/min.

I can provide anything needed, just not sure where to look.

Run NTtcp and IPerf to see can you network do wire speed. That's for the beginning...

Can you please provide some sample switches for these programs. I downloaded them and I know my ip's, but i don't know what you are looking for me to test.

Good IPerf user guide:

NTtcp user guide:

...and download link for the whole app in MSI + manual included:

That should help.
