[Skimmertalk] skimmer through Wintelnetx to AR Cluster

[Pete Smith]

This weekend was the first big test of the RBN Telnet server, and it is 
clear it needs some work.  There is plenty of machine, but the DXSpider 
software may need some tuning.  Last year, during CQWW, the original RBN 
web display system was lagging 30-45 minutes behind, a problem that we 
think was fixed by segmenting the database into daily pieces.  I think 
(though I'm no guru) that the serial Telnetting of DX spots to users may 
now be the bottleneck.  I suspect that the current crashed state of the 
RBN Telnet server may be the result.  Each spot is sent individually to 
each user, and that can be a lot of volume, particularly if users are 
relying on local software to filter things, so that everybody gets each 
spot, whether relevant or not.  It helps a lot if people filter at the 
Telnet server, and we *may* have to require that be done in some way.  
Stay tuned!
