Optimizing for high PPS, Intel NICs

I have an application that consists of a server and clients which communicate via TCP. The communication consists of exchanging many small packets - around 96 bytes of payload (non-uniform). I'm testing it in 8-CURRENT with two machines connected directly via a patch cable. The server is a 8-core X

Re: Hostapd network issue

Well, I haven't had a chance to switch cards, but on an interesting side note, none of my other wireless clients will connect after hostapd freezes. =W= On Fri, Sep 26, 2008 at 2:45 PM, Wayne Hendricks <[EMAIL PROTECTED]>wrote: > Well, the ap and sta are right next to each other. The sta is a Ma

Re: Hostapd network issue

Well, the ap and sta are right next to each other. The sta is a MacBook Pro. After a few minutes, hostapd freezes and the sta will not reconnect at all. Odd. I think i may switch cards and see if it helps. On Fri, Sep 26, 2008 at 12:46 PM, Sam Leffler <[EMAIL PROTECTED]> wrote: > Wayne Hendri

sfbufs on amd64?

When using sendfile() on an amd64 box, are sfbufs still used/needed? The reason I ask: # netstat -m 0/0/0 sfbufs in use (current/peak/max) 0 requests for sfbufs denied 0 requests for sfbufs delayed 1334122 requests for I/O initiated by sendfile kern.ipc.nsfbufsused: 0 kern.ipc.nsfbufspeak: 0

Intel NIC ARP problem

I have a strange problem with a PRO/1000 EB NIC (card=0x109615d9 chip=0x10968086) built into the motherboard (5000X chipset) that manifests itself in NIC stopping responding to ARP packets requesting its address while in Windows XP, after being rebooted from FreeBSD (dual-boot). The sequence is:
