Is gcc std::unordered_map implementation slow? If so - why?
...!!
With gcc-4.7
inserts: 37728
get : 2985
With gcc-4.6
inserts: 2531
get : 1565
So std::unordered_map in gcc-4.7 is broken (or my installation, which is an installation of gcc-4.7.0 on Ubuntu - and another installation which is gcc 4.7.1 on debian testing).
I will submit a bug report.....

Function that creates a timestamp in c#
...ToString("yyyyMMddHHmmssfff");
}
This will give you a string like 200905211035131468, as the string goes from highest order bits of the timestamp to lowest order simple string sorting in your SQL queries can be used to order by date if you're sticking values in a database
