Rick Macklem <rmack...@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rmack...@freebsd.org --- Comment #4 from Rick Macklem <rmack...@freebsd.org> --- Since no one else has mentioned this yet... The stats suggest to me that you've fragmented the mbuf cluster memory pool. 9K mbuf clusters are known to be a serious problem, see this recent post: http://docs.FreeBSD.org/cgi/mid.cgi?23756.39015.553779.526064 Some net interfaces have a setting that tells them to not use 9K mbuf clusters even if the interface is using 9K jumbo packets. If that exists for this net driver, I'd suggest you try it. For some reason, the stats show large numbers of both 9K and 4K mbuf clusters. (The 4K mbuf clusters aren't nearly as bad w.r.t. fragmentation, but mixing them with the 9K ones seems likely to cause fragmentation.) Alternately, I'd suggest you turn of jumbo packets and try it with ordinary 1500 byte ethernet packets. Hopefully others more conversant with this net driver and the mbuf stats will comment. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
