Hello, for this use case people typically use Symbols (much faster). Now you are right we may add a shortcut in string comparison. 2014-05-26 9:51 GMT+02:00 Philippe Marschall < philippe.marschall@netcetera.ch>:
Hi
I have been investigating why Dictionary look up performance with String keys is not as good as I would expected. Something I noted is that String
#= is implemented in terms of #compare:with:collated:. There is no short circuit if Strings are not the same size. In my case some Strings have the same prefix but a different length eg 'Content-Type' and 'Content-Length'. In that case a #compare:with:collated: is performed even though we know in advance the answer will be false because they have different sizes.
Cheers Philippe
