For guidance regarding the size see Setting the spooldb_slots parameter. Here we give some hints for creating a high performance spool. text/html 2014-05-18T14:22:44-04:00 http://wiki.noaaport.net/doku.php?id=projects:nbsp:articles:spooldb-slots.readme&rev=1400437364&do=diff May 2014 Setting the spooldb_slots parameter As of this date (Sun May 18 12:18:13 AST 2014) the Noaaport data and file rates are, on average, data rate r = 1 MB/s = 60 MB/min file rate f = 2500 files/min Let s = spoolsize in GB then minutes = s*1000/60 slots = minutes*2500
