This is how it can look like when switching from ADSL2+ (16 Mbit/s) to Cable (50 Mbit/s):
- lower latency on average
- increased Jitter
The latter comes from the fact that my new ISP does not provide me with native IPv4 but so-called DS-Lite: all v4 traffic is routed through a carrier-grade NAT. Not nice for port forwarding or real-time communication (VoIP impossible!), but hey: native IPv6! ;)
