Searched the mailing list, but I just don't get it: How do I interpret the output of netstat -m? The following example makes it confusing (all from 3.3 Stable) nmbclusters is supposed to equal 512+MAXUSERSx16, so the first example actually reduces nmbclusters from the default : Example: maxusers=256, nmbclusters set to 4096 %netstat -m 68/416 mbufs in use: 65 mbufs allocated to data 3 mbufs allocated to packet headers 64/182/4096 mbuf clusters in use (current/peak/max) 416 Kbytes allocated to network (32% in use) 0 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines Same Machine: maxusers=512, nmbclusters not explicitly set %netstat -m 68/128 mbufs in use: 65 mbufs allocated to data 3 mbufs allocated to packet headers 64/68/8704 mbuf clusters in use (current/peak/max) 152 Kbytes allocated to network (89% in use) 0 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines I will stick with this one example because it is very representative of what I have found. With the exception of max mbuf clusters in use my my numbers are lower when I would expect them to be higher: 68/128 mbufs in use: <- I would expect this to mean 68 in use out of 128 total, but this can't be right. 152 Kbytes allocated to network (89% in use) <- Why fewer? What does this really mean? Thanks, Dave To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
