   @Will-Lo , did you find that a lot of memory is consumed by duplicated strings created at this place?
   
   By the way, you can also check out string de-duplication feature of GC. It's benefit is that it will work on all strings automatically, but the downside is that it happens only after several collections and introduces overhead by itself.
