I had a need to throttle the bandwidth between sites to alleviate some bandwidth exhaustion so I implemented network throttling rules on the V&BR server down to 20Mbps which worked perfectly. I was even able to see on the gateway server the bandwidth usage drop right around to the throttled limit.
I have now removed the throttling rule but the it seems there is a hidden throttling rule capping the bandwidth usage at 100Mbps. Using throttling rules I can control the bandwidth successfully but as long I set the throttle limit below 100Mpbs, anything above gets ignored.
On the job bottleneck it lists throttling as the reason for the bottleneck which points to some hidden throttling rule still applying
I'm assuming I need to open a support case but I was hopping someone might have some insight beforehand.

Re: Un-throttling stuck at 100Mbps throttled
Hello
Yes, a support case seems to best option to investigate the situation. Please share the case number with me.
Just to have asked, did you have checked the throttling in new job sessions as well since you changed the throttling settings?
Best,
Fabian

Re: Un-throttling stuck at 100Mbps throttled
In my experience, such hidden throttling is almost always caused by some malfunctioning network port that failed over to 100 Mbps, so be sure to check that as well.

Re: Un-throttling stuck at 100Mbps throttled
@mildur , I'll open a case after the weekend. And no I didn't enable throttling in any job, only network throttling.
@gostev , if it would've been network port that suddenly malfunctioned down to 100mb than 1. bottleneck should've listed source/destination/network as bottleneck and not throttling like it did. 2. I shouldn't have been able to go anything above 100mbps but in my case and in all throttling cases the throttle number isn't a hard limit, it's possible to sometimes go a little bit over.

Re: Un-throttling stuck at 100Mbps throttled
Just an update, I haven't had time to replicate fully the initial situation. (The only way to confirm is to offsite copy a single big VM backup and remove throttling in the middle.
I can confirm that multiple smaller images do seem to get past the throttling but it's possible it's only images started to copy once un-throttled work normally and any images started during throttling stay throttled.
I can confirm though that the bottleneck algorithm seems to get stuck thinking throttling is at play, even though it's not anymore (confirmed via looking on the SMB gateway server the received bandwidth).
