4108GL IP Routing slow

Hello,

we use a Procurve 4108GL as backbone switch. Our LAN is seperated into four subnets which should be routed by the Procurve. Our problem is that routing between the subnets is extremly slow, we got ping resonses between 5 and 100ms, sometime even ping drops. CPU Utilization is about 20%.

Following the configuration of the ProCurve...
Regards,

Steve
