I upgraded my internet connection to 400/40 Mbit/s. (Docsis 3.0)
Modem syncs with 450560000 bps / 41984000 bps
Sqm is configured to ~ 95% of those values.
Speedtest shows around 350-365 MBit/s.
Without sqm i get ~ 430 MBit/s (-1518/1448 = ~ 450 MBit/s close to the syncrate)
Upping the download rate in sqm upto 450 Mbit/s makes no difference in download speed.
Always around ~350 Mbit/s.
Setting sqm download rate way higher then 450 MBit/s, like 500 MBit/s, does make a difference in download speed.
CPU usage is around 30%/80% (Dual Core)

I also have a different question about overhead (again :|)
I know, i already had a long discussion on the cake mailing, why overhead 18 is correct for docsis but
my modem shows this:
Maximum Concatenated Burst: 1522 bytes
Why did they choose 1522 bytes here and not 1518 bytes?
