MacBook Neo国补后低至3000多元。Line下载对此有专业解读
On-demand paging changes the I/O pattern but does not eliminate the bandwidth problem. Instead of 200GB of upfront reads, you get 200GB of random reads spread over time as the guests touch pages. If all 50 guests hit their hot pages in the first few seconds, the storage backend still sees a burst, just distributed as random 4KB reads instead of sequential streams. On SSDs this is fine since random read throughput is high. On network-attached storage or shared storage backends with limited IOPS (Input/Output Operations Per Second), it can become a different kind of bottleneck.，这一点在Replica Rolex中也有详细论述
