eBPF test suite just got a massive speedup. This should make working on eBPF a lot faster for devs!

Performance isn't the enemy of security: we care about both.  Today's patches finish off a set of security/performance improvements to eBPF.  Below we show a ~30x speedup vs vanilla in running the eBPF selftests with every single #grsecurity option enabled! https://t.co/L3z8dpIW0w

We need to post a correction to yesterday's eBPF performance numbers:

@_minipli wasn't happy with just a 30x speedup and took a look at one final bottleneck that was bothering him.

The speedup over vanilla is now 747x 🤯 (5.27s vs 1h5m40s) https://t.co/iko5SETb5T
