How to track network speeds - maybe through SQL or open to others

Question

The network speed is dramatically slower to the SAN, but it also makes me wonder how slow things are between the Webserver and the external world.
What's the best way to monitor what-I-assume are network delays and which part of the networks are causing the problem.
-- Needs to be run on the VM Machine xxxx to work
/* Local backup */
BACKUP DATABASE [play_pen] TO
DISK = N'x:xxxx\testbackup.bak' WITH COPY_ONLY, FORMAT, INIT,
NAME = N'Speed backup', SKIP, NOREWIND, NOUNLOAD, STATS = 10, CHECKSUM, CONTINUE_AFTER_ERROR
-- BACKUP DATABASE successfully processed 35289 pages in 7.638 seconds (36.095 MB/sec).
/* Intra-Network backup*/
BACKUP DATABASE [play_pen] TO
DISK = N'\\xxxx\testbackup.bak' WITH COPY_ONLY, FORMAT, INIT,
NAME = N'Speed backup', SKIP, NOREWIND, NOUNLOAD, STATS = 10, CHECKSUM, CONTINUE_AFTER_ERROR
-- BACKUP DATABASE successfully processed 35289 pages in 14.152 seconds (19.480 MB/sec).
/* SAN backup*/
BACKUP DATABASE [play_pen] TO
DISK = N'\\xxxx\testbackup.bak' WITH COPY_ONLY, FORMAT, INIT,
NAME = N'Speed backup', SKIP, NOREWIND, NOUNLOAD, STATS = 10, CHECKSUM, CONTINUE_AFTER_ERROR
-- BACKUP DATABASE successfully processed 35289 pages in 55.106 seconds (5.002 MB/sec)

Hi,
You can use the tools like Resource Monitor and Network Monitor.
Resource Monitor is a tool that you can use to monitor the usage of CPU, hard disk, network, and memory in real time. You can open it by clicking the
Start button. In the search box, type Resource Monitor, and then, in the list of results, click
Resource Monitor.  If you're prompted for an administrator password or confirmation, type the password or provide confirmation.‌
Meanwhile, I think it is proper to dig the networking issue on the Windows Server forum via the below link.
