Why does it matter? If you pragram in Java, you'd be programming against
the threading interface in Java, which is supposed to simulate threads
even if the underlying OS doesn't support it.

所以我就是想知道是不是所有UNIX OS都支持,
WINDOWS是否是真的THREAD调度的我倒不在乎
不然我就得做成多进程的来保证利用多CPU了

Either I misunderstood you, or you are saying multi-thread doesn't
utilize multi processor, which doesn't sound right to me.

Yes
这依赖于操作系统和JVM的支持程度

发帖数: 217 | 8 if you have a multi-processors machine, of course you will download
a JVM whose multi-threading support utilizes underneath multi-processors,
otherwise, what is the point of multi-threading?
