ER-X vs ER-Lite Head to Head Speed Results on Google Fiber

I've seen plenty of discussions here and on Reddit comparing the EdgeRouter X and the EdgeRouter Lite -- including why one or the other should or shouldn't be "theoretically" faster, particularly on Gigabit networks like Google Fiber.

 

Since I've had an ER-Lite replacing my Google Fiber box for a while now, I always wondered how the EdgeRouter X would compare, so I figured I'd dispense with the discussions and theory with some actual head-to-head comparisons in "real-world" conditions... and it would only cost me $50(ish) bucks for an ER-X to put the issue to rest (at least in my mind).

 

I have no bias one way or the other. I now own both devices, so I have no need to justify any purchase decisions based on my opinion. Let's let the data speak for itself.

I read your report, and I think I can fairly summarize this

as: for speed, it hardly matters which one you choose.  As

you say, it's not 'scientific', and there are a few anomalies.

 

Don't forget the ER-X-SFP: it provides the same hardware

switch as the ER-X, and adds 24V PoE support on all its

ports--as well as a Gb SFP port for fiber interconnects.   Dave

Hi @Dave-D. Well, I'd argue that it was technically "scientific," in that I used the scientific method (observation, measurement, experiment, then formulation of, testing of, and potential modification of hypotheses). Man Happy

 

But yes, it certainly wasn't performed in a pure labratory environment. But as I said in the article, nobody's residential Internet is in a lab environment. Removing all other clients from the network as about as close to labratory as it was going to get. Man Happy

 

Though if pressed, and someone asked me which one I believed was faster, I'd have to say the data points to the ER-Lite. Maybe it was faster by only by a little, but it was consisently faster, even on different days and with slightly different testing methodologies. The anolomies were small and few.

 

There are many in here that swore up and down (and I imagine they'll be along here in this thread soon) that there would be zero observable difference between the two. But until I see additional head-to-head tests that try to be as unbiased as possible that indicate otherwise, I have to rely on my results. Sure -- maybe it's only a 6% / 2% difference, but it's not 0% / 0%. Man Happy

Re: ER-X vs ER-Lite Head to Head Speed Results on Google Fiber

Looking at both devices, it really depends on just what you are doing with them.   If it's just layer3 routing (we have over 100 of these in our network doing just that) it really makes little difference.   But the fixed physical architecture of the Lite, with 3 ethernet ports connected to the 3 CPU ports is going to have less "stuff (highly technical trm there...) that the packets have to traverse than the switch based physical design of the ER-X.   But the ER-X has a faster CPU, and more efficient hardware offload.   Hence the toss-up in the testing.

Re: ER-X vs ER-Lite Head to Head Speed Results on Google Fiber

You measure a 2..6% speed drop.....

Results for ER-X are fine for most of us (including me)
If you do want to test and see way larger difference, run a test that simultaneously does up and download.

Re: ER-X vs ER-Lite Head to Head Speed Results on Google Fiber

a lot more on this here https://community.ubnt.com/t5/EdgeMAX/Google-Fiber-Which-router-should-I-buy/m-p/1393975#U1393975

 

tl:dr the ERL can do simultaneous 1G up/down while the ERX(in it's current configuration) can only do 1G up or down.

Re: ER-X vs ER-Lite Head to Head Speed Results on Google Fiber

Thanks for the great article. I think the results of your test showed insignificant difference between the two. The differences slight enough that you vary well could have seen the same difference between two ERL's side by side. As far as the 1gbs up and down vs up or down, I have read enough I believe it is the case, however, how often is anyone maxing the connection both ways? If they are, most likely they are a business customer and hopefully Investing little more money than either of those choices. When I was choosing what to buy, I thought about the ER-x, However only reason I went with the ER5 was I didn't want an extra power cable to the fiber jack.

Re: ER-X vs ER-Lite Head to Head Speed Results on Google Fiber

That's pretty much the same conclusion I offered.

 

But I don't understand what you mean by 'an extra

power cable to the fiber jack'.   Dave

Dave I think he means using a separate PoE injector...

Re: ER-X vs ER-Lite Head to Head Speed Results on Google Fiber

Yep that's what I meant. The router that google gave me is POE and Where my fiber jack is located there is no easy access to power.  So If I didn't replace it with a POE capable box, I would have to use an injector and it would have taken up another plug. Unfortunately where the router and stuff are located, power outlets are a premium resource, lol. As a side note, this is also why I went with a UniFi WAP as well.
