I'm curious. O:-)
Does downloading a dvd image have more impact of an ftp server than downloading (or installing) from the classical ftp tree, ie, each separate rpm? I mean, of course, with many simultaneous clients, as in gwdg.
Downloading a big image causes much less filesystem operations at the server than fetching a bunch of single files. At ftp.gwdg.de, just the filesystem I/O is the bottleneck.
I see. I was wrong then, I thought that many people downloading the iso images would be heavier on you than the same users installing by ftp.
But usually at the home user side the network is the bottleneck, so it makes sense to use an external server as the installation source. This way, much less volume has to get transfered.
Yes, that part I knew ;-)
But if the servers have a high load, this "less volume" transfer may need longer than the "big volume", due to filesystem latencies.
Yes, that's easy to understand. And I suppose that those programs that download big files retrieving diferent chunks (start points) at the same time from the same server makes things worse, specially for the rest of the users. :-? I have seen that working, but I have always refused to do it myself. - -- Cheers, Carlos Robinson -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) Comment: Made with pgp4pine 1.76 iD8DBQFEBKbctTMYHG2NR9URAn2wAKCVmpGKNSyglovtXd5Sjvn1H5t+kgCeNEAQ hNslFkteLENEajJyrFd/qvU= =sb66 -----END PGP SIGNATURE-----
