This research, which was presented at the recent USENIX symposium on Operating Systems Design and Implementation (OSDI ’21) conference, shows how a nanoPU hybrid approach might be the way forward for accelerating at least a certain class of RPCs — those with very small message sizes and usually a need for very small latencies — while leaving other classes of RPCs to use the normal Remote Direct Memory Access (RDMA) path that has been in use for several decades and 【that has pushed to its lower latency limits】.
that has pushed to its lower latency limits这部分显然是修饰the normal Remote Direct Memory Access (RDMA) path的，原文是不是应该是has 【been】 pushed to...才合理？
没理解pushed to its lower latency limits是意思。
