You'll have to look at consumption per SM to see the root cause....or to
prove whether something is wrong.
You can gather bytes transferred for each LUID on scheduled intervals.
Or I guess MRTG charts for each one if you prefer. You may find that a
couple of 1x and 2x users are using disproportionate amounts of data.

We have a few 450 AP's with 30-40 subscribers and have been getting
several slow speed complaints lately. I just chaulked it up to issues
with the SM since the AP rarely got over 20mb/s downlink. We upgraded
to 13.4 recently so we could watch our frame utilization. We started
graphing it over night and as you can see, we are hitting 100% for
sustained periods of time. During that time the AP is only doing
approx. 23mb/s. This particular AP has 34 registered SM and the
majority show 6x and 4x with 4 or 5 SM's at 2x and 1x. The performance
is a major disappointment. Anyone else have similar experiences?
AP configuration: 20mhz channels, 2.5ms frame, 10 miles, 75% downlink,
3 contention slots.
Attached is a screenshot of the utilization and sector throughput
calculator from the Capacity Planner R13.
