> Most of the time seems to be waiting for servers to respond, what probably means the bottleneck is on ad-network CPUs. A problem easily avoided by never making any requests to those servers in the first place. Block them at the point of ingress to your network (your router at home), on the clients (using /etc/hosts or equivalent) and by using blocking software in your browsers (uBlock et al). No ads, no problems. It will invariably also mean no access to some sites which either detect ad blockers (...which can be defused using ad-blocker detectors, this is a bit of an arms race) or depend on resources from ad servers (rare for now). You can either make exceptions for those sites or just live without them.
