So about every 200MB (i guess the linux box writes the data into the cache in the RAM first) linux writes the harddisk. But during that time - during the time it writes that 200MB to disk, there is no chance for any other IO. I'm playing an mp3 from the very same fileserver. It stops playing, because the machine does answer the read-requests. So what's going on here? Why does Linux write so huge amounts of data to the disk? Why does Linux not stop writing for a while to fullfil the read-requests? And so on ... Any idea, on how to imrpove that? --------------enigCB2B2516126396BA862820CF Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.1 (Cygwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFEqzV97Ww7FjRBE4ARAjXMAJ0a2DaZrLaGNvY2s2RHLQ1CAcI1TACfZbS0 reHesBdB0BOxICYozrHrypg= =66X6 -----END PGP SIGNATURE----- --------------enigCB2B2516126396BA862820CF-- -- gentoo-user@gentoo.org mailing list
