得益于这种巧妙的内存破解，Meta 节省了数百万美元

Engineers at Meta, Facebook’s parent company, have revealed how they have been able to offer free memory using a software solution called Transparent Memory Offloading (TMO).

It is now part of the Linux kernel and, in a nutshell, automatically offloads data to other storage tiers (e.g. Samsung’s CX memory expander) that are less costly and more power efficient than memory.
