In February of this year, I announced that Dolt releases are now built as profile-guided optimized (pgo) binaries, levering this powerful feature of Golang 1.20 to increase Dolt's read performance by 5.3%.. Prior to my announcement, Zach, one of our resident Golang experts, experimented and tested Golang's pgo feature and wrote about the performance gains he observed in Dolt after building it with profiles created while running our Sysbench benchmarking tests against it first. From there, we knew we had to get those performance gains into our released binaries, so we retooled Dolt's release process to build pgo releases..
