[Mono-devel-list] [IDEA] Caching String Hashcodes

[Andreas Nahr]

Hi,

I thought about a pretty simple thing. As strings are immutable we are able to cache their hashcodes. For (long) strings that make several calls to GetHashCode this would give us an incredible perf boost. However it will cost us 4 bytes of additional data per string even if the hashcode isn't used at all.

Should I go for it or leave it as it is?

Andreas
