I have a core router that is causing me alot of heart ache and i'm needing to find answers.
Problems & Issues:
1) Added Latency going through Router (Any traffic going through this router will increase latency by atleast 10%-15%)
2) Uploads aren't their fullest
Things tried to resolve the issue:
1) Bypassing router (This bypasses all these issues and we don't have any problems)
2) Disabled OSPF (Upload issue still exists)
3) Setup NAT, plugged in directly to MT, and tested speeds (Latency is still really high and upload speeds are still slow)
4) Swapped out router completely with exact same setup and specs (Problems still exist)
5) We recently upgraded to 2.9.42 before it was 2.9.39 and it still had the same issues.
Current Router Specs:
RouterOS 2.9.42
Pentium 3.0GHz
1GB RAM
2 x Onboard GB NICs
1 x 4 Port Routerboard 44
The average CPU usage is ~20%-25%.
The following uses for this router:
1) OSPF to Fiber connection
1) PPPoE concentrator
2) Dynamic simple queues for PPPoE bandwidth shaping
3) Input firewall rules to protect router
4) Forward firewall rules for standard virus ports
NO:
1) Mangling (tested with it and without)
2) Queue Tree (right now nothing is setup for queue tree & Again tested with it and without.)
3) NAT (We have all public ip addresses assigned to all customers through pppoe)
Do you think this is hardware related issue? Are is the routerboard definately causing my issue? Is there known issue with the new RouterOS that has issues with OSPF, PPPoE, Firewall, and Traffic Shaping?
Please help. I'm at my wits end.
BTW... This is a live router. So anything i do will take customers offline.
