Some router throughput reviews

Just picked a few popular routers to look over, some of the results are surprising and disappointing:

  • Linksys WRT54G2
  • Linksys WRT54GL
  • Linksys RVS4000 Security Router
  • Netgear FVS318G
  • Sonicwall TZ190
  • Smpl Route SR3E1W
It seems when I come into a clients small office and they say - ya I set it up, I hooked up the WRT54G2 - I say newer is not always better, looks like its only optimal at 8 simultaneous connections - although I doubt I would find an ISP with 70mbps throughput anytime soon, but it appears throughput problems start around 25 mbps. Quoted here:
"I did some additional investigation into the G2's simultaneous throughput problem and found that if I limit its data send rate to around 20 Mbps, I didn't see the throughput battle. But with a send limit of 25 Mbps, the problem reappeared."

It appears the WRT54GL is a pathetic example as well, completely dropping all communication at around 8-16 simultaneous connections - see the chart here. On a single download the GL appears to provide a very unstable 30-50mbps of through put.

Another sore looser from the bunch - Linksys (by Cisco) RVS4000 Gigabit Security Router with VPN, coming in at a blazzzing 14mbps max download (yes its gigabit) - its sad to say that this would not be sufficient for most cable modem connectons. But they call this a professional grade router - this is designed for the office?? - some smooth marketing pulled the wool over your eyes.

Netgear has some nice ones, but a popular one I often see is the FVS318G Gigabit VPN router. This guy can push about 22 mbps of raw throughput with about 200 max connections - not bad, not great.

And what about the resellers delight (Sonicwall loves a good reseller romance) - the TZ190, touted as a true enterprise product for the SMB, with 128mb of RAM, 16mb flash a 433mhz cpu and a dedicated VPN processor, it can provide a "blazing" 1.5 mbps of VPN throughput using 3DES. Such a "deal" at $1300 for the TZ190 with wifi, and annual support at $150 for basic and upwards of $800 (annually) if you get their full security suite (sweet reseller delight). Oh and the VPN is also another annual license cost - go figure, oh and not to mention if you need more than 1 office-2-office VPN - yes you need to upgrade to Enhanced OS, like routing packets with an elephant - bulky. Well their pure routing performance is about 25-26mbps of throughput - good for most cable modem connections (some max at around 30mbps).

The SmplRoute SR3E1W SMB router (by Simple Technologies), comes in at a blazing 88mbps of throughput with 2000 active connection states in the firewall (capable of 10,000+ states). With a 500 mhz processor, 256mb RAM and anywhere from 1-8gb of flash it can provide 30-35mb of VPN throughput. With no annual fees, anything less than $1300 would make this thing a smokin deal compared to a Sonicwall. We size the hardware based on your feature requirements, why would a basic small office router be suited to do complete antivirus, website, and spam filtering - this is like hauling a choo-choo-train with your F350 pickup truck.
