Corp for Atmospheric Research address@hidden WWW: http://www.unidata.ucar.edu/ =============================================================================== ---------- Forwarded message ---------- Date: Wed, 27 Oct 1999 13:39:05 -0600 From: Russ Rew <address@hidden> To: address@hidden Subject: current data feed volumes Hi, Just in case anyone's interested, here's some data I gathered over the weekend from the LDM running on shemp, which is getting all the standard data feeds plus three experimental feeds that I've also included separately at the bottom of the table. These statistics were digested from more voluminous raw statistics I also got on all the product sizes, including histograms of the product size distributions for every feed. This data is for a 24-hour period ending at 22:43Z 25 Oct 1999, during which there were a total of 5.8 Gbytes (365500 products) for all feed types, which works out to about 67000 bytes/sec, 241 Mbytes/hour on average.
