Re: z/OS network Speedtest
You are only going to transmit within the confines of your slowest network segment and any processor/WLM or I/O delays. Over the years there I have experienced a number of weird things that can dramatically affect ftp. I am sure that others can chime in. Tracking this down is going to take some effort. I would suggest a traceroute and ping test for starters. Then to a packet trace for portion of the ftp. I am sure your network folks have some tools to help out.

Mark, You keep saying G as in Gigabit speeds, but are you sure you don’t mean M as in Megabit speeds?

Re: z/OS network Speedtest
We have a customer that has to send us a large amount of data. They claim that our ftp server is very slow. I have had our network people tell me that we have 100GB pipe to our ftp server and if they say it's slow it is most likely their upload speed. I have tested the upload speed to our ftp server from my home network but I am limited to 5G upload speed, which I easily reach during the upload.

Re: z/OS network Speedtest
Mark Pace asked: >Is there anything for z/OS to measure upload/download speeds? >Like on a PC going to speedtest.net and running their test? How about...Speedtest.net? :-) This'd probably work on your z/OS machine: https://github.com/sivel/speedtest-cli Clearly you'll also need Python for z/OS, which Rocket Software graciously makes available here: https://www.rocketsoftware.com/zos-open-source You will also need network connectivity between your z/OS instance and Speedtest.net on the public Internet. And that's what you'll be testing, the whole path.

Re: z/OS network Speedtest
I have used ftp as well for speed approximations. Having a clear picture of your network layout will help. Kevin's point is very real.

Re: z/OS network Speedtest
Something we sometimes do is; Transfer large files with FTP from z/OS LPAR to another LPAR (or any host). The FTP program gives a nice report per certain amount of bytes transfered or time interval. (Either one of them, can't exactly remember which). It shows the amount of bytes transfered per second.
