I’ve never tried a DSA build for the r7800 (latest master after 23.05 branching). That is a good performance bump over swconfig if you are steadily in the mid to high 500mbps range! My numbers were NSS vs non-NSS for the older swconfig because that is where NSS works for ipq806x. For non NSS builds I regularly would get mid to high 400mbps… occasionally very low 500mbps for swconfig (5.10, 5.15 kernels).
