RE: rsync server

Anyway I think that a European rsync server is a must and since there are a lot of people that offered to serve it I think we should go ahead with it and make it official. There is no need for rsync.php.net to have an average transfer rate of 1.5Mbit while it can be less. Even if the network problems of rsync.php.net are solved for me it is still 26 hops away while fr2.php.net is 13.

(i've tested this by doing 'rsync --dry-run -a rsync.php.net::phpweb .' both locally and across the network -- locally it finishes in a few seconds, across the network it takes forever.) > Providing more rsync server would share the CPU load for the mirroring > process.

(but one big thing we could do to make the rsync setup more optimal would be to purge the 'plain' versions of the manual. once someone gets around to do a print-friendly stylesheet for the un-plain version, it will make sense to do this.) > To answer to the question of Spyros in his first post, the average > speed I get on rsync.php.net is 4Kbytes/s from rsync.php.net to fr2.php.net, i get ~45KB/s. from two other machines, i get well over 100KB/s. jim
