Description (partial)

Symptom:   download performance problem, (eg: ftp file transfer)

Conditions: QOS enabled or QOS disabled.
Because the downlink speed was 100Mb, and the uplink speed was 1000Mb the
downlink was experiencign congestion.  
Due to the size of the buffer, the FTP server was bursting larger than the
interface could buffer. Thus packets were dropped.

This can be seen on 2960S, 3560C and 2960C
