Sadly that's often the way it has to be done, modulo mild tweaks.

As others have said upthread in more polite wordings, get a better 
router if yours can't handle the load.  (Or use the route servers more

I hope you didn't change the MTU to anything different from what 
everybody else on the DE-CIX Peering LAN uses - that only leads to 
suffering.
