According to the Cisco command reference (and according to my results), setting the srr-queue bandwidth limit to 90 limits throughput TO 90% - not BY 90%. "srr-queue bandwidth limit 90" sets interface idle time to 10%, while permitting traffic 90% of the time, so the result is an effective 90 Mbps on a 100 Mbps port. Note that although this command accepts any value between 10 and 90 inclusive, the interface idle time is adjusted only in increments of 6. Rather than rounding to the nearest multiple of 6, it appears to truncate. So, "srr-queue bandwidth limit 10" actually results in 6% throughput, but "srr-queue bandwidth limit 12" results in 12% throughput.
