Is there any reason to believe that using the new -webSocket mode for 
agents would be any less sluggish at archiving artifacts from agent to 
master than ssh mode? 

Using the ssh-slaves-plugin I'm getting abysmal throughput (~13Mbps) when 
artifacts are being copied from agent to master, despite their 10GBps link: 
https://issues.jenkins-ci.org/browse/JENKINS-7921

Reading up on some of the conversations on this long-standing issue over 
the last decade, I'm not confident that this performance is going to be 
improved. So, I'm considering alternatives, like using WebSocket agents. I 
read here 
<https://issues.jenkins-ci.org/browse/JENKINS-18276?focusedCommentId=249851&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-249851>that
 
the problem might be that "Jenkins archives via its control channel (e.g. 
ssh slave - using java SSH implementation JSCH). The java ssh just can't 
get anywhere near 1Gb/s network speed that native SSH can manage easily"

So, I was just wondering if WebSocket Agents might perform better at 
archiving artifacts bc they are implemented so differently.

Thanks,
