poptop - hundreds processes.. :(

Hi,

I am running poptop on the suse 9.1. It is beeing used for many
endpoints and I seem to run into trouble with performance. I think
that 700 processes(in my case) causes lot of context switching
overhead.

Is there any other option, where there would significantly less
processes involved?
I do not think then "process per tunnel" is the best solution from
performace point of view.

lot of thanks for any hint
