 Subject:  Re: [m0n0wall] Does Traffic Shaper Suck??

I have done a number of speed tests, and they all report that both my 
upload and download speeds are equal (around the 1380kbps range - when 
measured at separate times)....

I think my mistake may be in not understanding the different speed units 
used. I can't quite seem to get a grip on this!

I have also tried to ensure that my wireless is stable at speed. I 
started to download a debian ISO as a test and cut my download speed 
back until I saw no dropped packets over a 15 minute period.

At this download speed, Firefox reported that the download speed was 
around 130KB/s, and the traffic meter on m0n0 was listing the download 
as 900Kbps.

The traffic shaper lists speed as Kbit/s..... I assume that this is the 
same unit of measure as the traffic graph's Kbps?
