Hey Albert,

these numbers are quite impressive but I can't quite explain those. Are you 
measuring maybe a full debug build without any compiler optimizations? Then 
the library sizes will be _much_ larger and thus trigger more page faults. If 
every one of those is extremely slow on that machine compared to more modern 
machines?

May I ask how old this machine is and what the speed of the HDD is?

Thanks
