[c-nsp] Cisco 3640 Maximum performance

[Nicolaj Ottsen]

Our expirence is that it depends a lot of the kind of trafic - surprice
:)

"Hosting trafic" (Lots of http) : we have seen packets loss (underruns)
on the 3640 at 20 - 30 Mbit, upgrade to 7200.
"Streaming trafic" (Radio etc) the 3640 does close to 100 Mbit.
"Enterprise trafic" (random mix) : No practical expirence with this but
I would expect about 50 - 60 Mbit.

Actually, you should get a lot more than 70-90Mbit/s out of the
platform.

Let's assume a forwarding rate with 50.000 packets per seconds and
packets of 1000 BYTES, That gives 50.000.000 BYTES/Second = 50 MBYTE /
Second =
+- 500 Mbits / Second.

The actual performance can be higher or lower, depending on
software/hardware features used.

Kind regards,

Koen.

Hello,

 

I will appreciate any information on the Cisco 3640 maximum performance,
maximum traffic load it can handle without any problems. According to
Cisco documentations it should be around 50-70 kpps which, according to
me, it should be approximately between 70Mbps~90Mbps. The problem is
that I have never loaded it with more than 10Mbps. Currently I'm in the
phase when I need to put 34Mbps on it. This is the reason way I would
like to here some practical experience from you. Of course the router is
accepted to stay 100% reliable. The router has the following parameters:

 

cisco 3640 (R4700) processor (revision 0x00) with 92160K/6144K bytes of
memory.

Processor board ID 28509225

R4700 CPU at 100Mhz, Implementation 33, Rev 1.0

Bridging software.

X.25 software, Version 3.0.0.

SuperLAT software (copyright 1990 by Meridian Technology Corp).

2 Ethernet/IEEE 802.3 interface(s)

2 FastEthernet/IEEE 802.3 interface(s)

4 Serial network interface(s)

DRAM configuration is 64 bits wide with parity disabled.

125K bytes of non-volatile configuration memory.

16384K bytes of processor board System flash (Read/Write)

 

The router has CEF enabled on it and it should route the traffic between
two FastEthernet ports. If you need any info about the IOS it is
c3640-is-mz.122-26.

Thanks,

Atanas
