[-- Attachment #1 --] Hi, all. I've got a very complex problem so every advice is appreciated. I've got a router on 4.3-STABLE FreeBSD. It's got hardware (in short): - Intel Pentium III 500 MHz - NIC 3Com 10/100 in 100baseTX <full-duplex> - NIC 3Com 10/100 in 100baseTX <full-duplex> - NIC 3Com 10/100 in 100baseTX <full-duplex> - NIC 3Com 900 Combo 10baseT/UTP <full-duplex> - NIC 3Com 900 Combo 10baseT/UTP <full-duplex> Sometimes through this router network works slowly and it is natural right thing. Therefore we are going to split router on two. My questions are common for such situations: - How trobleshoot network activity? - How can I find bottlenecks in this situation? - What counters should I examine? - What is the maximum limits for such counters? (As I can examine interrupts but I don't know reasonable limits. I've heard about maximum 4500 interrupts). - What are advices for improving the configuration? (except hardware routers) May be there are web resources for troubleshooting such situations and finding bottlenecks. Thanks in advance. Dmitry.
