Hey all! Something I've noticed with the last three firmwares is that only one CPU is being taxed when the router is under load. When I first got the router I would see two CPU's being taxed under load reaching to about 50% usage for two cores, now only one core goes to 50%. I know theres a GT-AC5300 thread already but did not want this to get buried in and lost as this can be a serous issue. For us using this router we paid the premium to get a Quad Core router and reap the benefits of its processor, if we are not getting even half of its full potential then its a problem. We paid for a GT but getting the performance of RT. As you can see in the screenshot the router is under load and will only go up to 51% on one core, most i've seen it go up to is 60% for one core and the rest are at a steady 0% or 1%. I was hoping everyone else can test this out to see if they are experiencing this. I'm currently on the latest firmware 3.0.0.4.384.32738, but have also experienced this on the last three firmwares.
