This neat StackOverflow answer appears to be by the 'atom' fellow who contributed a patch to make the collector more precise (patch review = https://codereview.appspot.com/7307086/): http://stackoverflow.com/questions/7823725/what-kind-of-garb... Atom also says 1.0's was more conservative, but, as Brad also said, still didn't scan "objects such as []byte" (meaning all plain-old-data arrays? who knows). The Go 1.1 Release Notes mention the collector becoming more precise, which was a particular issue on 32-bit because big heaps could span a lot of the address space. You can see the GC source itself doing some per-type switching:
https://code.google.com/p/go/source/browse/src/pkg/runtime/m... At some point, this sort of discussion probably gets you less useful info per unit effort than just playing with a Go distribution, trying out whatever toy programs you find interesting. |
