Re: netmap, netmap-fwd, and how many M packets-per-second?

Hi, I have run some performance tests but not as router, which is your case, so some information might not be relevant: 0. validate your hw stats with what you get from the output 1. Try using FLOWTABLE option in your kernel config - this may kill your machine in -CURRENT, but it's worth checking

Re: netmap, netmap-fwd, and how many M packets-per-second?

Hi, If I'm getting it right, you are doing a test with 10 machines directly connected on the same LAN, using iperf to test the performance of the TCP/IP stack with your 10Gbit cards. But as far as I can see, netmap is not involved in your setup, you are not using it, aren't you? IOW , I don't und

Re: Looking for some help with netmap/bhyve

Hi, Thanks for testing, the numbers you report make sense, 7-15 Mpps is good for an old machine. On my machine I get 25 Mpps, so probably you could get something similar with newer hardware. The crash dumps you reported are not related to ptnetmap, but to the emulated (aka generic) netmap mode d

File duplication on NFSv4 exported ZFS filesystems to centos client

Curious phenomenon of file pseudo-dup with exported ZFS filesystems on FreeBSD 10.3-REL NFSv4 export to a centos7 client. *FreeBSD server-* zpool create zpool_nfsv4 ... zfs create zpool_nfsv4/zfs2 zfs create zpool_nfsv4/zfs3 /etc/exports- V4: / /zpool_nfsv4 /zpool_nfsv4/zfs2 /zpool_nfsv4

mutex usage in if_bridge vs other drivers

I'm not sure if this is really a freebsd-net topic or more generic kernel, but since I observed this by looking for possible causes of a bizarre network driver crash I'll send it here (I'm not on the freebsd-net mailing list but I'll check the archives for a bit too). When doing if_bridge SIOCSDRV
