argus memory use on Linux 2.2.18

[Chris Newton]

Hi,

  This loaded machine, can you give me some details about the link it is 
watching (how many in/out MB/s), how many machines on the network, and what 
the class of the machine is (PIII 600Mhz?), and how much memory?  I can't 
really help with the problem you are having... but, I am wondering how well 
argus scales.  Also, what % CPU is argus using to watch this link?

Thanks

Chris
