src/runtime/tracetime.go
// // Hitting this target resolution is easy in the nanotime case: just pick a // division of 64. In the cputicks case it's a bit more complex. // // For x86, on a 3 GHz machine, we'd want to divide by 3*64 to hit our target. // To keep the division operation efficient, we round that up to 4*64, or 256. // Given what cputicks represents, we use this on all other platforms except // for PowerPC.
