[uml-user] tun/tap Performance: msg#00329

Subject: [uml-user] tun/tap Performance
Hi *,

first of all: Thank you for a great piece of software, UML rocks!

I observed that the performance of tun/tap network interfaces depends on the speed of the host CPU: On a Xeon 550 MHz processor the maximum speed across a tun/tap device is somewhere around 55 MBits/s with 100% CPU utilisatiion. On a 1 GHz Athlon CPU the speed of the tun/tap device exceeds the 100MBit of the external interface. Is this a bug or did I hit an actual limit? Does anybody else have a slow CPU and can confirm my observation?
