Hello all:

I'm running Xen with Gentoo. I setup two network device in Xen guest Gentoo. One of them connect to the Dom0 ethernet card via bridge, and the other connect to Dom0 wireless card via another bridge. The interface in DomU connected to the outside ethernet device have throughput close to Dom0. (927Mbps / 917Mbps) However, the wireless interface have very poor bandwidth (2.2Mbps / 90 Kbps). Is there a reason why wireless transmission is extremely inefficient ?
