Slow throughput
I'm trying to get ATM working on an Intel linux machine. Machine stats:
kernel: 2.2.1
ATM for linux: 0.55
distribution: RedHat 5.2
PCA-200E: 0.4
Ethernet: Intel EtherExpress Pro 100
My problem is this. Whenever I try to use the atm as the primary interface (use the ATM gateway ) the system slow to a crawl network wise. The machine is part of a large network with many automounted NFS volumes and YP/NIS. I can't seem to figure out what could be wrong. As far as I can see I have everything set up correctly. Is there any way to enable debugging message for the driver so I can see when and how frequently the VCs are being created and torn down? Can anyone offer me any insight as to what all these stats mean? Thanks ahead of time.
Sorry for the legth of the message but I wasn't sure what to/not to include.
