How would option 1 affect GC performance for 1M small object collection/compaction? I assume it would slow down the GC, but perhaps not enough to worry. 2. If we break through the ~85K large object size, would option 1 start fragmenting memory? By creating >85K strings? Then creating a new 85K StringBuilder object every time would definitely impact performance negatively. 1. How would option 1 affect GC performance for 1M small object collection/compaction?

My results for 1M (your code): new = 00:00:02.3437500, append = 00:00:01.9843750 So, while Option 2 is faster, nobody is really going to notice it anyway.
