Hi, 

When I changed network settings of my Virtual Machine to "Bridged: Connected directly to the physical network", jobs is done extremely slow.

I have Jenkins server which is installed on Virtual Machine, when the IP of virtual machine is "local" (e.g. 192.168.1.20) jobs are done quite OK (~6minutes per build).

But when I changed IP to domain IP (e.g. 3.194.15.23) build are soooo slow (up to 15 hours!). I changed IP due to fact, that I want to connect with server (from web browser) from every computer in network (not only from VM host computer)

I tried almost everything, changed proxy setting, changed Java proxy settings, increase Java buffers, turn off the antyvirus and still nothing.

This is not compiler/computer issue, because when I start compiling from command prompt (directly where the Makefile is), clean is perform quick, via Jenkins it stuck first time at:

mkdir -p XmlConfig

and take ~3minutes when in "normal" build it take ~100ms

any ideas where is the bug?

UPDATE: When I change the IP settings in windows, and when there is no communication to e.g. SVN, compilation works fine (of course its not solve my problem)

So my guessing is that this is some buffer in Jenkins after connection to WAN?
