This is a very important point. By turning the cache on, you have not resolved an underlying performance issue, if there even is one. Please try dd again with a well-sized bs= parameter, or use some more accurate reporting like iozone, sysbench, etc.
Also, I am not sure how much memory is on the card, but that is likely COMPLETELY in cache at that point so you're not learning anything. Write a couple gigs to get some real numbers. -Patrick 2008/6/9 Wojciech Puchar <[EMAIL PROTECTED]>: >> dd if=/dev/zero of=testfile >> 165760+0 records in >> 165759+0 records out >> 84868608 bytes transferred in 25.028232 secs (3390915 bytes/sec) > >> I think I ought to be able to get more than 3.2MB/sec out of this card, > > with default 512 bytes blocks - not much more > _______________________________________________ > email@example.com mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "[EMAIL PROTECTED]" > _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
