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.
