Jenkins ec2 plugin - windows slave is very slow

Question

enter code here I'm trying to use jenkins ec2 plugin and I have problems with performance. My options for winrm:

winrm set winrm/config/service/Auth @{Basic="true"}
winrm set winrm/config/service @{AllowUnencrypted="true"}
winrm set winrm/config/winrs @{MaxMemoryPerShellMB="1024"}

Jenkins 2.133 OS Windows 2016r2 Java 8 x64

My next steps took a lot of time:

11:47:48 Building remotely on zak-test (sir-4pcr5aig) (zak-test) in workspace c:\jenkins\workspace\AT_PES_test_zak
11:58:48 Cloning the remote Git repository

next step

12:07:52 Parsing POMs
12:39:51 Established TCP socket on 49811

When I use JNLP protocol instead WinRm my tests are work without these pauses. Quickly.

Moreover, I created task https://issues.jenkins-ci.org/browse/JENKINS-53617 but i didn't receive response.

then, I use local windows user jenkins for connect from master to windows slave ec2 instance. I launched gui tests by google chrome. When tests is working I'm connecting via RDP to my slave windows host and I'm watching that chrome is working in background. But I didn't see my browser as GUI process. Only in powershell:

Answer 1

WinRM is slowly protocol. Despite this plugin is very comfortable for using Linux instances.
