I remember someone complaining about the speeds writing to a unc file share over a 10G network, using a blackmagic file writing test tool

It was really slow (about 100MB/sec), but iperf was fine.

I did a "while (true) pkill sophos" or similar. Speeds shot upto about 1GB/sec.

Closed the while while loop, sophos returned in a few seconds, and speeds reduce to a crawl again.

But who needs to write at a decent speed in a media production environment.

And people still wonder why ShadowIT constantly wins with the business.
