Excel Binary Names

<t>The unordered map works well with Boost locking so that multithreading works. I am just trying to work out how to persist the Map at Save and Open Time.

VBA Wrapper/UDF/Excel Dependency Tree Problem

<r>One reason your VBA UDF is very slow is probably because you have not bypassed the VBE refresh buf: this will slow down your VBA UDFs by a factor of 10 or more.See writing-efficient-vba-udfs-part-3-avoiding-the-vbe-refresh-bug <URL url="http://fastexcel.wordpress.com/2011/06/13/writing-efficient-...

Excel 2007: Slow VBA

<r>Excel 2007 VBA has a higher overhead per VBA/Excel data transfer call than previous versions, so the advantage of transferring data in large blocks using arrays is even greater with XL 2007.Make sure you are using Excel 2007 SP2 (SP2 contains a VBA speedup fix).My timings for your benchmark (scre...
