I searched a lot but I found nothing helpful...

Is there an easy way to benchmark the cpu of a dd-wrt router and compare the results with other dd-wrt routers with different chips and firmware size?

I know the results are not perfect because of the implementation and cpu features, but that's not the problem. I just need something to compare the CPU performance of a bunch of routers.

Maybe a command or script I can run over SSH?

Thanks for any help.

@ eibgrad
Thanks for your answer, you're right...

My Problem is, I have about 20 (twenty!) dd-wrt routers (accumulated over time). Almost all different models. I have 2x Internet (High Bandwidth) and want to rebuild my whole "small" home network: 2x Internet-Router with QoS, 4 Router only for VPN, and 3 WLAN APs. Not sure if I use some for NAS. And on top, power consumption is an important point too.

Afaik VPN, QoS and NAS are very CPU dependent. And now I try to figure out wich router I best use for what, and which ones I sell on ebay...

Iperf is very good to show the network performance.
I hoped for something I can run on the command line that show me the approximate computing power of the CPU. The result does not have to be very accurate. Simply an approximate value that I can compare.

I would be very grateful for ideas.

just google router model/name and add wiki at the end..
aka wikidevices...
there is a good info about all known routers and their specs...
appart of that use to most powerfull for vpn just bare in mind you need at least dual core cpu routers for it

I can't tell you much since I don't know what router model you may be considering for what but since imma just goofy around and just to give you an ideal.
It might really help you deciding about an openVPN router Cool
'here is some openssl speed tests' using the
EA8500 (Qualcomm IPQ8064 @1400MHz dual core) and the WNDR3700v4 (Atheros AR9344 @560MHz)

I'm told the Netgear R7800 (daul core @1700MHz) will do better than the EA8500 but I don't have one and have no use for one Twisted Evil

NOTE: I don't know for sure what dd-wrt routers you can run these type tests on .... I know same openssl test will NOT run on my old broadcom E2500

Your EA8500:
sign verify sign/s verify/s
rsa 4096 bits 0.052684s 0.000671s 19.0 1491.3


My R7800:
sign verify sign/s verify/s
rsa 4096 bits 0.044512s 0.000560s 22.5 1787.3

@ Alozaros
thanks good idea, but the specs are not the problem, I have an excel sheet with 'em for all routers.

Funny, I have a R7800 - a real beast! ^^

Belkin F7D4302 V1 (480MHz)
Netgear WNR2200 (360MHz)
Netgear WNR3500L V2 (480MHz)
Netgear WNDR3800 (680MHz)
Netgear WNDR4300 V1 (560MHz)

My focus is at the moment to these devices. But because of the similar MHz, it is unfortunately not easy to find out which router has the best computing power, and rank them. More MHz does not automatically mean more computing power.

IMHO, netcaster and aside from your R7800, the WNDR4300 is the best overall router you have listed Smile
