This reduces latency > for plasma clients, and also improve the actual throughput for plasma store. > I made a simple prototype for changing Release() function as well, when > batching release 10 objects in a single IPC, it only takes about 1/6 of the > time compared with using 10 separate IPCs. Also from profiling, processing > IPCs takes a lot of CPU cycles in plasma store currently, as UNIX domain > socket processing needs to go through kernel, thus batching multiple IPCs > into a single one should greatly improve the plasma store performance as well. > > This change mostly applies to Release(), Seal(), and Create() interfaces. -- This message was sent by Atlassian Jira (v8.20.10#820010)
