banIP support thread

Is anyone actually able to enable all of the blocklists without completely destroying the performance of their router?

I'm running OpenWrt on an x86 mini PC, so no shortage of CPU power or memory, but when I add some of the larger sets the performance of the firewall for forwarded traffic completely tanks, packets are lossed left right and centre, and the internet connection basically becomes unusable. Here's a Thinkbroadband monitor plot, with the problem shown very obviously during a period where the total number of IPs in my sets was around 300,000:

If I disable some of the larger sets (e.g. becyber and pallebone) to keep the number of IPs below 100K, performance returns to normal.

This seems to be an nftables issue, and I originally reported problems in this area here, but I've never seen anyone else complain about it so I'm wondering if it's something that's specific to x86, or even specific to my particular router.
