[jira] [Commented] (ARROW-15229) [C++][FlightRPC] Evaluate UCX/RDMA transport performance

["Yibo Cai (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-15229?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17477578#comment-17477578 ] 

Yibo Cai commented on ARROW-15229:
----------------------------------

I tested on two servers connected by 100Gb network, FlightRPC DoGet benchmark speed is 2634 MB/s for gRPC, and 3874 MB/s for UCX/RDMA. Looks great.

Please note current code is not stable for RDMA. Most benchmark tests hang, only very few tries happen to work. And UCX/TCP benchmark is much worse than gRPC. I think there are still big potentials to improve.

> cc [~lidavidm], will be great if you can give a stable branch (or commit id) for evaluation purpose.
