I ran the lotsaints test from last email on an i7-10750H (~3 years old) and got these results (gcc 13.1 , turbo off): REL_15_STABLE: latency average = 956.453 ms latency stddev = 4.854 ms REL_16_STABLE @ 695f5deb7902 (28-JUL-2023): latency average = 999.354 ms latency stddev = 3.611 ms master @ 39055cb4cc (31-JUL-2023): latency average = 995.310 ms latency stddev = 5.176 ms master + revert c1308ce2d (the replace-palloc0 fix) latency average = 1080.909 ms latency stddev = 8.707 ms master + pg_strtoint_fastpath1.patch latency average = 938.146 ms latency stddev = 9.354 ms master + pg_strtoint_fastpath2.patch latency average = 902.808 ms latency stddev = 3.957 ms For me, PG16 seems to regress from PG15, and the second patch seems faster than the first. -- John Naylor EDB: http://www.enterprisedb.com
