What you think about optimal hardware about cacheex=3 exchange. Please give some examples from your system also how much load cost you this version on exchange.
I think the crucial thing is amount of RAM, will be more than 1.5 GB.
My system has 512 MB and this is not enough for cacheex=3 , all the time oscam fill out the RAM and use the swap also crashed recently.
Today i upgrade the RAM to 2GB and the difference is a appear at the moment (more stable and low CPU usage).
For CPU more than 1.5 GHz is needed my cpu is 2.8 GHz P4 for now is ok.
