## Compiler {#compiler}

|
The build time overhead to building with [Profile Guided Optimization](/doc/pgo) has been reduced significantly.
|
|
Previously, large builds could see 100%+ build time increase from enabling PGO.
|
|
In Go 1.23, overhead should be in the single digit percentages.

<!-- https://go.dev/issue/62737 , https://golang.org/cl/576681, https://golang.org/cl/577615 -->
|
|
The compiler in Go 1.23 can now overlap the stack frame slots of local variables
|
|
accessed in disjoint regions of a function, which reduces stack usage
|
|
for Go applications.
