Hi, Sorry but I"m a bit confuse,
1. What should I do ? 2. Is there a solution ? 3. Is there a workaround ?
I'm going to try to do something about this for 1.50 (i.e. to be released in 3 or 4 months). I tried gcc 4.7's implementation and it's pretty similar to boost 1.46, a tad faster at lookup. Your benchmark might perform better but it wouldn't if you always look up different values (as you would in real code). I don't know about libc++ or Visual C++'s implementation. If you can't wait for 1.50 then your best bet is to use something like google's dense hash containers, and try to make sure your hash function works well with them. Or if you feel like being brave, I'll add the new version to trunk around the time 1.49 is released.
