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 - NIC 3Com 10/100 in 100baseTX - NIC 3Com 10/100 in 100baseTX - NIC 3Com 900 Combo 10baseT/UTP - NIC 3Com 900 Combo 10baseT/UTP 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?=20 - 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. ------_=_NextPart_001_01C18227.AAC352A7 Content-Type: text/html; charset="US-ASCII" Content-Transfer-Encoding: quoted-printable Router based on FreeBSD.

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.
