XG-7100 efficiency low?
-
Yeah those numbers seem what you would think.. So the question now is helping the OP figure out what is going on in his testing.. Prob have to prove to him that something is not wrong with his hardware..
Or what could be in his config that could be causing the problem.

I cannot duplicate @mke's findings:

They are still investigating this but so far cannot replicate the problem. Since I have more than one XG-7100 I did more testing but not with iperf but real pipes at two different locations, result was the same(struggling to go over 1gig) and I even did video on this and sent them but can't post since it shows my IPs and I don't have time to do editing.
-
So can you duplicate their iperf testing?
-
What I would love to do is to do iperf across real links with multiple sites with mix of xg7100 and SG-8860 all with gig pipes, not sure if will be able and right now I have very limited time.
-
do you have any of the switch ports still open - you could use those without disruption of your active links.
-
I don't have access to those devices since they are in different locations so physically it is problematic to do testing right now.
-
I got finally an answer after multiple test using multiple XG7100, different routers, pipes, core switches, combinations. It ended up that testing in the real world using same website is misleading. I did try different speed tests but wanted to use that same particular on both laptops because for higher speeds it gave me very good results(single laptop) that reflected situation however while testing multiple computers it showed bottleneck on their side, sick.

Thank you for coming back and reporting your findings.
That is why one should not rely on external test sites when testing device performance.

@Derelict said in XG-7100 efficiency low?:

You don't say ;) heheheeh
