We recently bought an IAP-135 to take a look at it.
It currently has the latest firmware version 126.96.36.199-188.8.131.52.
The problem I have is that the CPU usage goes up to 90% when i'm transferring data at speed about 100-110 Mbit/s
At this time i'm the only client on the IAP and have and established connection with a linkspeed of 300Mbit/s
If the CPU is used for 90% during 100Mbit transfer, what would the CPU usage be if the total transfer speed came closer to theoretical 900Mbit/s for this AP?
So, the question is, is it ok for CPU consumption to be that high ?
And of course I understand that 300mbps is only a linkspeed,theoretical maximum speed. But isn't 100 Mbit/s too low for a linkspeed of 300?
Thank you for your opinions.

this seems to be related to the following post:
On my deployment, CPU usage went to normal usage level after disabing MAS integration.

But looks like this is not the case.
Although I was telling about 184.108.40.206-220.127.116.11_35320, actually I had the same picture even with 18.104.22.168.
As you recommended, I tried disabling MAS integration, but not sure if it worked. Reboted the IAP and found MAS integration enabled again. So far I wasn't able to have it disabled after reboot.
Luckily, I noticed that a new firmware version had just become available - 22.214.171.124-126.96.36.199_35899. (The IAP is Dell-branded, so all firmare updates come later than for original aruba devices)
After upgrading to 188.8.131.52-184.108.40.206_35899, I was able to disable MAS integration (it stayed disabled even after IAP reboot).
But still no difference in CPU usage.
When i Hit 100-120 mbps, cpu usage hits 80-90%. When there is no transfer - it is used for 10% on the average
Could someone share their normal CPU usage under heavy load, say when IAP transfers total of more than 100mbps ?
