Very good question, answer is no for the following reasons:
- it happens for all downloads - yum, wget etc
- I have looked at the interfaces using ngrep, all traffic goes straight out through the closest (as in hops) interface
- As you raised this I have disabled caching on the command line using wget, still happens
- As you raised this I have checked whether there are any (environment) options set, none
I, too, use the same bash scripts on all machines I have
I though about the interfaces, but can't be. The last two interfaces are on the problem machine, but when downloading on the LAN I get a throughput of ~28mbs, only when downloading on the gateway I only get <10mbs.
So still baffled.

Computing power increases as the square of the cost. If you want to do it twice as cheaply, you have to do it four times as fast.
