Performance of 2.4.0-pre2 is terrible as it is now. There is a big
performance drop from 2.4.0. Simple test (that is not excessively
swapping, I remind) shows this:
2.2.17 -> make -j32 392.49s user 47.87s system 168% cpu 4:21.13 total
2.4.0 -> make -j32 389.59s user 31.29s system 182% cpu 3:50.24 total
2.4.0-pre2 -> make -j32 393.32s user 138.20s system 129% cpu 6:51.82 total
