I don't know who is responsible for documentation but I ran into this @ http://www.oracle.com/technetwork/java/javase/gc-tuning-6-140523.html.
"Survivor Space Sizing
If desired, the parameter SurvivorRatio can be used to tune the size of the survivor spaces, but this is often not as important for performance. <----
Sorry to disagree but I find proper survivor space sizing to be critical to good GC performance more than 1/2 of the GC problems I run into a due to premature promotion of object due to improperly sized survivor spaces. This leads to frequent full GCs.
