With microthreads, it is possible to run tens of thousands of parallel processes on a moderately capable modern PC, and to switch between contexts hundreds of thousands of times every second.
有了微线程，我们就可能在目前中等性能的 PC 机上运行数以万计的并行进程，还可以每秒钟几十万次地在上下文之间切换。
However once it leaves the city, the vehicle is able to switch to a dedicated concrete track which runs parallel to the motorway and accelerate to a cruising speed of around 150mph.
不过，一旦巴士离开该市，就会转至专用水泥路面，与高速公路并行，并加速至巡行航速，约150英里/小时。
In particular, having a read-barrier allows you to switch to a simpler GC algorithm - and a simple algorithm can be more easily made parallel, scalable, concurrent and robust.
特别是，拥有读操作屏障允许你切换到较简单的GC算法—更易于并发、扩展和强壮。
