Will my current AC56U be able to support?

[OKLY]

Hi all,

Currently I am using an AC56U clocked at 1000,666.

My current Internet speed is 100/50 mbps. At the moment my router has no issues and is more than capable enough, even when it serves as an OpenVPN server I can still get 50mbps at client's side.

Starting next month, there will be a free upgrade given by my ISP and I'll be getting 800/200 mbps.

Question is, will my current router still be capable enough to handle it?

BogoMIPS figure as below.

Processor : ARMv7 Processor rev 0 (v7l)
processor : 0
BogoMIPS : 1998.84

processor : 1
BogoMIPS : 1998.84

FWIW: You should be able to come very close to hitting your 800Mbps max download throughput w/this router according to Tim's review...

The test would have probably been done in stock processor clock speed and since it can manage to get near 800mbps of WAN-LAN throughput, I believe mine will be slightly more comfortable since it is running at slightly higher processor clock speed.

Either way, would the processor be under high load when there is 800mbps of data going through the router in this case?

The CPU and switch chip of the RT-AC56U is the same as the RT-AC68U so the performance should be the same as seen in Tim's review of the RT-AC68U. So provided you're using hardware acceleration the throughput should be as shown. CPU load should be fairly low because hardware acceleration largely bypasses it. Of course if you use features that disable hardware then you will be CPU-limited to about 300Mbps.

Only CTF will be good enough right?

I think you'll just have to wait and see, everybody's use case if different. One thing's for sure, your line upgrade won't make your existing router slower.

By way of comparison, here are my CPU loads when pulling my maximum line speed of 380Mbps (no QoS or anything else enabled).

No H/W acceleration: 65%
CTF only : 35%
CTF+FA : 1%

Note that with H/W acceleration disabled and QoS enabled the most I can get is 260Mbps (but that's highly dependent on the number of rules). In this situation the throughput is CPU limited because QoS is single threaded and one of the CPUs is at 100% while the other is mostly idle.

This was with my RT-AC68U overclocked to 1.2GHz/800MHz.

I have also been reading that with FA on top of CTF, the CPU load goes down tremendously. However I've came across some comments that mentioned if I'm using PPPoE and VLAN that it is advisable not to turn off Spanning-Tree Protocol (which in this case FA will never be enabled).
