The dev is not ignoring any question nor is he purposely introducing "bugs/limitations" for windows miners. If anything, you're wrong in assuming that biblepay is a linux guy as even the pool is running on windows.

The f7000 algorithm modification has been extensively talked about the past few weeks including why it was/is necessary and its consequences. There was major issues when it went live so our dev was busy dealing with all of that and I think he did an admirable job in dealing with that chaos. He was also busy fixing the pool and dealing with DDOS attacks so that you could still keep mining using it.

Finally, performance is something difficult to understand as there are so many factors affecting it; from your CPU, memory, disks, internet connectivity to w/e is running on your machine and could interfere with the mining software) and we're talking about a brand new algorithm on top of that! It could even only be an issue with how the hashrate is calculated VS your actual performances.

The performance issue on windows has only been there for a few days and Robert (biblepay) said that he is now looking into it. It might take a long time as troubleshooting performance issues on a specific platform is not an easy task.
