[Dxspider-support] Raspberry Pi DXSpider Node

[Bill Shell]

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.

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?
