Sorry that I'm not answering to original poster, but this message is
for him
I just found in my old bookmarks this page:
https://supportforums.cisco.com/document/31581/egress-qos
which provide detailed example how enabled mls qos can decrease packet
drops for specific type of traffic.
Some time ago I tested setup with 1G to 100M ports and also 2G
Ether-channel to 1G port with different size of burst and confirm that
you can get some improvement but only for temporary congestion or only
one class of traffic.

If Thres1 in Q1 is set to 1000%, this would mean 500 buffers. Where
are the 500-200=300 additional buffers borrowed? From the common
pool?
From the document
---
Anything over 100% means the tx queue can use common buffers to queue
packets. The default value for this field is 400%.

I've not worked with small cats in several years and I'm not ready to
refresh my memory on them, as I don't expect needing to work on their
QoS in future, sorry.
