RmACK: It appears that I can get good(ish) sustained transfers e.g. 2Mbit from California which, albeit 3x slower than usual is fine. Pings are also a tad higher than usual but still sensible around 180ms, and pretty consistent.
Yet page elements each take 2-4s to load on affected sites.
Is it possible for there to be some issue that could make establishing connections very high latency, without actually having too much impact on the throughput of said connections once established?? To load an image from my server in a browser takes 1-1.5sec to start but achieves over 2Mbps.
yeah transparent proxies being overloaded .. and sticking outstanding requests into a queue.
