In addition, because the literal block data is stored in memory, little or no massaging of the in-memory data is required before writing it to disk, greatly reducing CPU overhead.
此外,因为文字块数据存储在内存中,这些内存数据在写到磁盘之前,不必或只需作很少更改,大大减少了CPU开销。
The overhead averages about (m + b) bytes (ignoring the Pointers at the beginning of each memory block).
内存开销大约为(M + B)个字节(每个内存块开头的指针忽略不计)。
Each object allocated on the GC heap has an 8-byte overhead (sync block + method table pointer).
每个在GC堆中分配的对象有一个8字节的头(同步块+方法表指针)。
