RE: [freenet-support] datastore size
There should be a relationship between bandwidth and store size. At a guess, it's exponential, doubling the bandwidth can support a store 4 times larger. Estimating this relationship would be valuable to the people running nodes. ++PLS -Original Message- From: Derek Ferguson [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 10, 2004 4:07 PM To: [EMAIL PROTECTED] Subject: RE: [freenet-support] datastore size * Replies will be sent through Spamex to [EMAIL PROTECTED] * For additional info click - http://www.spamex.com/i/?v=3880664 Hmmm. Am I wrong to think there probably is an optimal store size for each node? My thinking is that as the store grows, the node draws more requests, which at some point will exceed the node's ability to service them all in a timely manner due to resource limits (probably bandwidth). As the store grows larger, even more requests come in, causing the node to service a shrinking proportion of the total number of requests directed towards it, which has a negative impact on the network. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Martin Scheffler Sent: Tuesday, August 10, 2004 3:40 PM To: Steve; [EMAIL PROTECTED] Subject: [freenet-support] h Am Dienstag, 10.

That's quadratic, not exponential. The store size would be scaling with the square of the bandwidth, not 2 to the power of something proportional to the bandwidth. ___ Support mailing list [EMAIL PROTECTED] http://news.gmane.org/gmane.network.freenet.support Unsubscribe at http://dodo.freenetproject.org/cgi-bin/mailman/listinfo/support Or mailto:[EMAIL PROTECTED]

The first is the request success rate (which makes your node attractive), another measure (request rate limiting) tells the other nodes to reduce the requests/time, to balance out all the peers with your avaiable bandwidth. A big store is good (even for yourself). good byte pgp3utfkDm14e.pgp Description: signature ___ Support mailing list [EMAIL PROTECTED] http://news.gmane.org/gmane.network.freenet.support Unsubscribe at http://dodo.freenetproject.org/cgi-bin/mailman/listinfo/support Or mailto:[EMAIL PROTECTED]
