Yes indeed! I wrote that: "For me it is unfortunately not possible to run linux on my pc's because they must run 24/7 on win64. It would be really great if somebody  could compile a x64 wallet!" 
Good to know that the VB doesn`t perform that good. Do you have any comparison numbers, eventually in percentage, about the performance differences between 32bit windows wallet, 64bit in VB and 64bit in native linux? 
I am asking that because with a fulltime job, an extra big project, a small mining farm and two small kids and a wife at home it would be pretty frustrating  to invest time to install linux in the VB and the find out that there is almost no performance gain...
