Hello, I was using an othello program "WZebra" on windows and I was reading and writing a file called book.bin with this program. Now I prefer and use Linux for some reasons. I have installed WZebra under WINE because the linux version get several bugs. Then I have tried some version of Wine and actually I have the last version 1.1.22 compiled. I don't have a problem of time to read the file book.bin but only when WZEBRA is writing. with WZEBRA + WINDOWS : total time : about 5 secs with WZEBRA + LINUX + WINE : total time : about 200 secs Any idea to improve this time under wine please? Thank you in advance if anyone can help me 9ae6
