--nextPart2127607.jZeyMfI2Dc Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Content-Disposition: inline Sorry if you can't hear any more performance problems, but I'm wondering wh= y I=20 can't write to my 5.3-stable NFS server more that 3,5MB/s while reading giv= es=20 me 9,5MB/s? Server has a "em" card, client is also 5.3-stable with "fxp", but if I try = it=20 from my debian box with a "em" card avarage write performance is also bad b= ut=20 with strange peaks. The first second almost no data gets written to the dis= k=20 and then it peaks up to 7,5MB/s, but like said, average is also about 3MB/s. The server can easily handle 35MB/s (twe 4x160GB R5) and was idle while=20 measured! Thanks for any clarification (I tried different -w and -r sizes, but that=20 hasn't changed anything) or confirmation of that problem. =2DMano --nextPart2127607.jZeyMfI2Dc Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (FreeBSD) iD8DBQBBh3agBylq0S4AzzwRAh5qAJ9Ggn7PMxu4D5NrUXxuepJdoBlU+ACcDnT3 M8ZuCSJ/nVAhrm9SCVvkxtU= =fp6k -----END PGP SIGNATURE----- --nextPart2127607.jZeyMfI2Dc--
