Marius,
Do you have any explanation why the script requires a powerful router? Is it just the general inefficiency of the MikroTik scripting language execution, is there some operation called by the script that takes a lot of CPU, or is there a chance that by using a more efficient algorithm (e.g. optimization of the case that nothing changes for an entry) a lot of performance could be gained? I ask this because your approach is of course the easiest to have everything integrated on a single router, vs two alternatives that could be considered: - run a Metarouter which does the multipoint IPIP tunneling and runs ampr-ripd - run a Metarouter which runs the python scripts that update the config on the main router

Rob,
The slowest part in the script is finding a route which uses a certain gateway, in the obsolete interface check part which leads to the big load at the end of the run time. I have a version using a dynamically built interface array created during obsolete route check. This array is then used to check for unused IPIP interfaces.
This allowed me to reduce the runtime from 4 minutes with some 50% load (1 full core) to under 1 minute with maximum 35% load.
If it works OK i will publish it soon.

if you want me to test it post me privately this one seems to be hanging in
