I have to wonder why Linksys is ok with having such a mismatch in up and downlink throughput in this (or any, for that matter) router. The Star processor obviously sucks up a lot of processing power crunching its IPS checks. But even with those features disabled, download throughput doesn't even match its bread-and-butter WRT54G and is more on par with products a few generations back.
While 10 Mbps+ connections are still in the minority in the U.S., there are plenty in other places around the world. If you happen to have one of them, you'll probably want to look elsewhere for a router that lets you take full advantage of that bandwidth that you're paying good money for. It's too bad, because otherwise the RVS4000 has a lot going for it. Where else can you get a four port gigabit Level 2 managed switch with jumbo frame support for around $125?
