thanks a lot for the replys. I did not try the renice and nice commands yet .. but I will the execution of my program is remotely... I mean, its a remote execution of it. the program is in PC Numer1, when PC Numer2 wants to exec the program, executes it .. with remote execution . maybe thats why maybe its a little slower ... maybe there is a way to agilize SAMBA , or to integrate in a better way SAMBA and wine ... I dont know
