基于SPDK的CurveBS PFS存储引擎 ## Why ·为了减少使用cpu做内存copy，减少系统调用 发挥某些被操作系统屏蔽的功能，例如nvme write zero ·根据阿里《When Cloud Storage Meets RDMA》的说法 ·在100Gbps网络带宽时，内存带宽成为瓶颈 Intel Memory Latency Checker (MLC)测试得到的CPU内存带宽是61Gbps ##

reload does not reload extensions musl libc's dclclose is a no-op Complicating thread-local storage (TLS) implementation if library may unload Better than violating the language rule, if live objects loading a library, initialize objects with static storage duration at namespace scope • When unloading a library, destruct objects with static storage duration Reminder: loaded libraries are reference When a thread starts, initialize objects with thread storage duration at namespace scope - When a thread exits, destruct objects with thread storage duration What happens if the library is unloaded before
