Great news! I just canaried 1.6 RC1 to a real production host. For a Go app using about ~10GB of memory, the already good GC times look even better on my 1.6rc1 canary (the blue line) vs 1.5.3 (the rest):

Here the times have also dropped a lot: from about 3ms to 1.5ms, with otherwise everything the same, as far as I can see. Nice!

Just out of curiosity, can this be attributed to a single change or is it a lot of smaller things?

Thanks!

Excelent, memory usage seems to be slower than golang's 1.5 version !

Did it cause your app to become more responsive? Is cpu use less overall here, as well? Just wonderin'.
Also anybody have some example "compile times" 1.4 v 1.5 v 1.6?
Cheers!
