System: NetBSD karo.kortex.jyu.fi 1.6_BETA5 NetBSD 1.6_BETA5 (experiment) #0: Sat Aug 10 17:37:23 EEST 2002 karo@experiment.kortex.jyu.fi:/opt/sources/src/sys/arch/sparc/compile/experiment sparc
Architecture: sparc
Machine: sparc
>Description:
I use qec SBus card, which has 4 ethernet slots. If I transfer data 
through le0 (integrated Lance) and qe0 everything works fine, but if I  
transfer data through qe0 and qe1 the transfer speed will stay at 
600kB/s instead of the 1M/s (10Mbit/s) and the system loads will go up  
to 5 and higher and the system really freezes. I use this machine as a  
router/switch/firewall, so qe0 and qe1 are in different subnets.
