If people can't check for database updates more often than once an hour, then there is a pressing need. The mirror page talkes about the need for mirrors, about exponential growth, and how at least a 10mbit pipe is needed to host a mirror. It puts March 2004 traffic at about 120gig/month Some quick calculations: daily.cvd is about 150k compressed, 334k uncompressed -- let's say 50%. Greping the virses added for updated 447 gave me about 3k uncompressed -- so let's say 2k compressed, on the outside. For 2k of update, everyone downloaded 150k. That shows (at least for that update) only 1.3% of what was downloaded was needed. If only 1.3% of every update is actually needed, and people only downloaded what they needed, the traffic on the mirrors would drop from 120gig/month to 1.6 gig/month. If I am completely off by a factor of 10 -- say only 10% of every update is actually needed, traffic on the mirrors drops from 120gig to 12gig. There are a lot of assumptions here, but I would think ever reducing the load on the virus servers by half would be significant. ========================================================== Chris Candreva -- [EMAIL PROTECTED] -- (914) 967-7816 WestNet Internet Services of Westchester http://www.westnet.com/ ------------------------------------------------------- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 _______________________________________________ Clamav-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/clamav-users
