I’ve got a question regarding slowdown in certain use cases. My setup is as
follows:

Server A – Cloud VM, Ubuntu 14.04.1 LTS, Jenkins 1.583 Master, Artifactory
Pro 3.5.3
Server B – Cloud VM, Ubuntu 14.04.1 LTS, Jenkins Dumb Slave
Server C – Less capable local VM, Ubuntu 14.04.1 LTS, Jenkins 1.596.1 Master

I have a job on Server A that uses the Artifactory plugin to download a file
(964MB). When I set it to run on Server A, the job runs in about 20s. If I
instead set it to run on Server B, the job takes approximately 100s.
Finally, if I have the same job on Server C set to run on Server B, it takes
a whopping 600s.

Can anyone explain why the speed of the Jenkins master affects the download
speed on the Jenkins remote?
Ignoring question 1, why might the download to Server B be so much slower
than Server A? The network speed between the two machines has been tested to
be near 35MB/s, but we’re seeing only 9.5MB/s through this test.

Data (MB)       965                     
Master  Source  Destination     Job Time (s)    Speed(MB/s)
Server A        Server A        Server A        22      43.86363636
Server A        Server A        Server C        101     9.554455446
Server B        Server A        Server C        600     1.608333333

Thanks,
Daniel Sirgey
