Although there could be minor performance differences in the aic7xxx driver in the latest 2.2 kernel and the latest 2.4-test kernel, there would *not* be the kind of difference you have listed in your email. In actuality, the kind of differences listed in your email appear to be strictly of the "the 2.4 kernels aren't doing aggressive read-ahead any more and my sequential input numbers are sucking as a result" variety. I would suggest reposting your email to the linux-scsi@vger.rutgers.edu and also to the linux-kernel@vger.rutgers.edu mailing list since this would be far more topical on either of those lists and since the problem could theoretically reside in either of those areas, they are both somewhat appropriate. -- Doug Ledford <dledford@redhat.com> http://people.redhat.com/dledford Please check my web site for aic7xxx updates/answers before e-mailing me about problems To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe aic7xxx" in the body of the message
