[Skimmertalk] CPU for Skimmerserver

[marcelo at alternex.com.br]

Wow, thank you all for all the answers.
It seems that the i3 system I am looking at is quite good for the job. In fact, even
the Atom 330 I currently have at the remote station might work!
Thanks Bob, N6TV for the useful benchmark link.
Pete, for sure the skimmers will connect to the RBN. I am travelling to Florianopolis
in South Brazil  (@ PP5EG - PT5T)this weeked to put the first one on. I did some
very limited tests from home during the CQWW weekend.
Again thanks for all inputs and help.
Here is the summary. I´ve included the CPU MAX TDP - Thermal Design Power
- as a hint to the energy consumption.
