Hi Bill

GB7DXG-1 has been running on a Raspberry PI  for over a year now without any issues

All,

The computer at W6RFU failed last week.  To get it back in service and as a temporary measure, we installed a Raspberry Pi with Raspbian OS and DXSpider.  I was a little worried about the loading on the system since I have only used a Raspberry Pi for my N6WS-2 node that has never had more than 3 users.  I was especially concerned about the Raspberry Pi system loading with this being the weekend of the 160m Contest, the BARTG Sprint, and the first day of FT5ZM.  The system is operating with
37 users, connected to three other nodes, and it seems to be working fine.  The CPU loading is hovering around 10% and only about 50% of the RAM is used.  The CPU resources do make it up to an average of 17% over a 5 Sec average during high peaks.  I also have all debugging turned off just to conserve on resources.

%Cpu(s): 17.1

I am monitoring the output of W6RFU compared to a few other adjacent nodes, and there is no perceivable delays in sending of spots to users or passing data to other nodes.

Is anyone else using DXSpider on a Raspberry Pi with comparable loading, and are you running into any problems?  The W6RFU installation was temporary to get it back into service, but from what I am seeing of today's performance, it may become permanent. Anyone have any comments or recommendations that may change my mind?

TU es 73,
