> as you said vmware is a program like hole computer inside a computer,but you said that it is slow ,why it is slower than wine while >it access directly to hardware,and as vmware is slower because it emulates a whole second computer inside your real machine. Not all of the emulated machine accesses the hardware directly. The slowdown also depends highly on the application. As a programmer I see the slowdown daily. It typically takes 2 to 10 times longer to build applications. The graphics is also significantly slower and the hard drive is much slower. I believe memory allocations are slower on vms versus real hardware. >i know wine has not access hardware directly? Yes but it uses a single driver that has direct access to the device. vmware in a lot of cases is using 2 drivers and fake hardware. John
