Thank you for bringing this to our attention. It seems the Support Chat has an issue. We are actively looking at it to get it corrected ASAP.
Regarding the throughput issue, it certainly doesn't sound right. Could you share some additional details on the client, OS version and software version you are using? We will test this internally to see if we can recreate the issue. It would help if you could lodge a support case (with phone or chat once it is functional) so we can get your logs and other details to debug.
This is certainly not expected. We regularly run a suite of tests before each software release and have run several tests since you reported the issue. All our tests show high throughput in several hundreds of Mbps, as you would expect from any Aruba product. We will analyze all the details you share with the Support team to get to the root cause of this issue and address it appropriately. As you suggest, this issue may be limited to specific client/OS or setup. Thanks for your patience on this while we investigate this further.
