What is the absolute fastest microwave PTP or multi-PTP WDS throughput possible with Mikrotik ROS (in a real-world installation of several miles) ?
I am currently running several Mikrotik AC mimo 2x2 WDS links using the NV2 protocol with the following settings:
- NV2 Cell Radius: 10
- NV2 TDMA Period Size: 2ms
- All boards over-clocked to maximum (720 MHz on my 922UAGS-5HPacD RB equipment)
- Passing lots of 802.1q tagged vlans
- hundreds of MAC addresses on different vlans on both sides of the WDS link.
- No firewall rules - no routing - only WDS bridging
- No CPU resource consuming scripts or configuration (just keep it simple and as fast as possible)
I suspect I am running out of CPU throughput capability when I sustain 400 meg and faster throughputs.
At 500 meg sustained throughput , I often see a sustained CPU load of 75 percent or higher.
Am I correct in guessing the less than 1 GHz CPU on the various Mikrotik routerboards just can't handle that kind of throughput work load without introducing some propagation delay times in the networks ?
I normally consider any CPU load on any network equipment greater than 10 percent a potential need for hardware upgrade.
I normally consider any CPU load on any network equipment greater than 20 percent as broken.
(higher CPU loads = network propagation delay)
So - I ask a couple of questions:
#1 - using 100 percent Mikrotik hardware/software, is there a faster throughput solution ?
#2 - using ROS on an Intel CPU (non Mikrotik motherboard) with Mikrotik wireless mini PCI-e (mini PCI express) cards, can I build a faster WDS outdoor-tower-mounted hardware solution ?
A 720 MHz 922UAGS-5HPacD RB tops out at 1.5 gig when performing a UDP btest to 127.0.0.1
A 3 GHz Xeon based motherboard running VMware ESXi hosting a 32-bit ROS tops out at 19 gig when performing a UDP btest to 127.0.0.1
I am guessing that directly booting ROS instead of using a hypervisor will provide even faster results closer to 20 or 30 Gig.
Has anybody built and tested something like an Alix 1pu1d motherboard (or something else) running ROS in a WDS tower-mounted environment using AC NV2 mimo 2x2 or 3x3 ????
Any advice and information is welcome.
I am ready to buy and try ...
