Kazar and Manni, if possible could you please share the build commands you use? I see regressions for an inlining patch (dc592a4155) too when I build postgres with -O2. My build commands are: -O2: meson setup buildtype=debugoptimized ... -O3: meson setup buildtype=release ... This is a wide benchmark only, old master means b2ff2a0b529 without 0001 inlining patch (dc592a4155): +--------------------------+---------------+---------------+ | | Text | CSV | +--------------------------+-------+-------+-------+-------+ | -O2 | None | 1/3 | None | 1/3 | +--------------------------+-------+-------+-------+-------+ | Old Master | 10440 | 11000 | 11940 | 13600 | +--------------------------+-------+-------+-------+-------+ | Old Master + 0001 | 10140 | 10800 | 11600 | 14300 | +--------------------------+-------+-------+-------+-------+ | Old Master + 0001 + 0002 | 9000 | 11000 | 8850 | 15300 | +--------------------------+-------+-------+-------+-------+ | | | | | | +--------------------------+-------+-------+-------+-------+ | | Text | | CSV | +--------------------------+-------+-------+-------+-------+ | -O3 | None | 1/3 | None | 1/3 | +--------------------------+-------+-------+-------+-------+ | Old Master | 10440 | 11200 | 12200 | 14390 | +--------------------------+-------+-------+-------+-------+ | Old Master + 0001 | 10000 | 10700 | 11540 | 13960 | +--------------------------+-------+-------+-------+-------+ | Old Master + 0001 + 0002 | 8880 | 10900 | 8900 | 15100 | +--------------------------+-------+-------+-------+-------+ This result shows that when we compare v18 and v18 + SIMD (0001 + 0002), there is only regression for the CSV 1/3 case. The regression is %12.5 for the -O2 and %5 for the -O3. -- Regards, Nazir Bilal Yavuz Microsoft
