Sorry guys, the ASUS RT-AC68U Interest List/MO is off

Maylyn kana banned? what happen? He doing a good deed to help us here with the MO... like that straight ban meh?

What can we say? the MODs are working really hard into everything we say.

And Maylyn is not evening doing a MO in the first place. He's just trying to help people.

true he's helping us out...

but it's still against HWZ's rules. Let's be reasonable and don't flame the mods just because they were doing their job.

A warning could have been given though instead of a ban outright... unless there's other reasons which caused the ban.

A shame though was looking at his computex posts(halfway) and realized he was banned...

were they ? every little thing have to ban.

they can easily move it out to the respective thread (like what they are capable of doing). But they chose to ban instead.

When will this model hit the store? I just went IT show at Expo AC66U going for $299. I'm willing to wait if this new model hitting the store in few weeks time.

ASUS RT-AC56U

Firstly, sorry for a lack of new updates, it's not that there is any but a lot of hard work and contribution from RMerlin in the new Broadcom ARM Cortex A9 firmware development and bugs fixing has already begin behind the scenes weeks ago which the upcoming ASUS RT-AC56U and ASUS RT-AC68U are based on.

Some teasers from RMerlin himself



Some good examples why the new upcoming ASUS routers will fly

What can you expect out of an ARM A9 dual-core CPU?

OpenVPN throughput benchmark:
iperf -c 10.16.0.1 -M 1400 -N -l 64K -t 30

The iperf and OpenVPN servers were on the router, and clients were a Win7 laptop connected to the WAN port.

RT-AC66U (FW 3.0.0.4.270.25): AES-128-CBC [152] 0.0-30.0 sec 79.5 MBytes 22.2 Mbits/sec RT-AC56U AES_128-CBC [156] 0.0-30.0 sec 217 MBytes 60.7 Mbits/sec
For OpenVPN, this router is a beast

Here's the raw OpenSSL performance. openssl speed test:

RT-AC66U: type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes aes-128 cbc 9398.56k 9941.17k 10138.71k 10195.09k 10234.54k RT-AC56U (with ARM ASM optimizations backported from OpenSSL 1.0.1): type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes aes-128 cbc 25596.63k 28151.82k 29251.64k 29363.88k 29587.09k
That's right. OpenSSL raw performance is nearly 3x faster on the RT-AC56U.
One core was indeed topped. The current bottleneck lies at the irq level, so I doubt that SMP can help with that. Someone told me that this is an inherent problem with gigabit Ethernet, which generate a lot of interrupts to process. The closed-source ctf module must be doing something about it beyond just bypassing netfilter steps.

Might be worth digging through more recent kernels to see if there are any optimizations done at Linux's level to help with these.

On the other hand, having SMP does mean that while you have one core heavily loaded with traffic, the other core can take care of other things like Samba or Transmission. I believe that dual-core will be a great benefit to modern routers who are now designed to do much more than just route packets.
Tonight I did a few file transfer benchmarks (over Samba). The results are quite nice.

I copied a 1.2 GB video to, and from a USB 3.0 disk plugged to the router. The disk is a pretty standard 750 GB laptop HDD inside a 2.5" NexStar 3 enclosure. The disk was formatted as ext3. The client was a laptop using a gigabit cable plugged to a LAN port. The speed as reported by Windows 7's copy dialog:

Code:

Write speed: 30 MB/s
Read speed: 50 MB/s

I have to admit, I wasn't expecting such a high read speed. The actual network throughput according to the System Monitor was around 450 Mbits throughout the read test.
Source ~> Teaser-time! - SmallNetBuilder Forums

As for myself, I'm equally busy as well in assisting RMerlin in correlating test results based on his new firmware releases almost every couple of days and i have my own tests as well which includes getting static IPv6 and DHCP IPv6 compatibility support for our local usage.



So stay tuned for more if i have time to post more

Wow looks nice.
But isn't the naming convention a little off? AC66 lose to AC56?
Any idea when it's coming to SG?
I can sign on the fibre now but I'm waiting to see if MR can provide AC56.

I wonder Edimax AC1200 USB adapter better or Asus AC1200? i heard that Asus USB-AC53 is not that good compare with some brand like Cisco

i think you meant "Linksys"

and Linksys = CMI.

Taking a break off the usual testing and catching up some rest, I'm back with more reporting

Since I'm on the dual core ARM Cortex A9, some might wonder is there a need for routers to move to multi cores to provide better performance? IMHO, it's definitelyYES in our local context especially for FTTH aka Fiber users and the multiple tasks that users use their routers these days

Up for thoughts and discussion

Just quoting some interesting quotes from RMerlin for the night and some updates.

The areas where this new CPU will be of benefit:

- People using the VPN server (either Asus's PPTP, or Tomato/A-M OpenVPN)
- People with a lot of clients sharing files over USB
- People who can't use HW acceleration because they use QoS. (lack of HW acceleration drops max WAN speed from 700+ Mbps to around 150 Mbps on an RT-N66U, about 240 Mbps on an RT-AC56U).

Note that the R6250 does not have both CPU cores enabled, so it's not a good test case.. No idea about the DLink/Linksys products.

I can see in the latest FW code I got from Asus last week that they are making efforts to specifically optimize the FW for taking advantage of the two CPU cores.

The faster CPU will not have a big impact on your actual wireless performance, but it will have a measurable effect for people heavily using a shared USB disk or using features that disables HW acceleration.
Netgear specifically states on their site that the R6250 has a dual core cpu.

'The dual-core 800 MHz processor delivers high-performance connectivity'

Maybe the other core comes online under heavy load only?
No. It was deliberately disabled by them. I got confirmation of it from an inside source.

Same thing with the missing 128 MB of RAM - router should have 256 MB, but Netgear only enabled the first 128 MB.
29/06/2013

Under a week's time since his ASUS RT-AC56U 3.0.0.4.372.30 beta 2 firmware, RMerlin has released his 3.0.0.4.372.30 beta 3. Numerous bugs fixes are done @ nvram level and by far it's the most comprehensive customised next generation Broadcom dual core ARM Cortex A9 DDWRT firmware.



As we are kinda running out of bugs to find so the next stage for us to correlate stability tests and results.

IPv6 6to4

I was sidetracked in trying out the IPv6 6to4 using HE tunnelbroker on SingTel Fiber as well

Hi guys, any advantage of getting the AC56U or AC68U if I am just a casual user?

The only thing I do is play games online (BF3, STO, WOT etc...) Do some downloads from time to time and BT.

Using Sintel 300Mbps. currently using AC66U. If AC56/68 can lower ping or improve DL/BT speed it will be great.
