If your internet line is not something close to 3,5Mbps then most likely havp is eating up most of your memory. I am not using proxy server on ZS cause it makes some streaming radios, that I listen to, stop working. Try to upgrade the memory for a start.
It finally worked! – I transferred Zeroshell to a machine with more resources: P4 2.8GHz, 1GB RAM. Apparently is was a lack of RAM causing HAVP to run slow. Thanks ppalias.
It appears that HAVP can’t catch HTTPS. Is this correct? What can be done in this case?
