Palo Alto Prisma Access client bandwidth degradation

We just recently purchase Palo Alto's Prisma access solution and notice that bandwidth is for users with high speed internet (1gbps). At first I thought this could be a wifi interference problem or something else, so to isolate out all those variables, I decided to run these test on a linux server with GP 5.0.9 on GCP.

I seem to have found some very interesting statistics. I used a n1-standard-8 (8cpus, 30gb ram) instance and ran the test with and without the GP client. Here are the stats...

``` -------------WITH GP-----------------------
user@instance-3:~$ speedtest-cli --simple
Ping: 31.575 ms
Download: 250.10 Mbit/s
Upload: 230.51 Mbit/s
user@instance-3:~$ speedtest-cli --simple
Ping: 28.773 ms
Download: 241.40 Mbit/s
Upload: 214.32 Mbit/s
user@instance-3:~$ speedtest-cli --simple
Ping: 28.729 ms
Download: 243.25 Mbit/s
Upload: 203.31 Mbit/s

--------------WITHOUT GP -------------------
user@instance-3:~$ speedtest-cli --simple
Ping: 32.858 ms
Download: 2088.64 Mbit/s
Upload: 221.67 Mbit/s
user@instance-3:~$ speedtest-cli --simple
Ping: 30.414 ms
Download: 1978.77 Mbit/s
Upload: 210.96 Mbit/s
user@instance-3:~$ speedtest-cli --simple
Ping: 23.552 ms
Download: 1390.41 Mbit/s Upload: 240.83 Mbit/s
```

Looks like the download has a cap of 250Mbit/s as GP can't get past that in the download. But without GP, I get greater than 1,000Mbit/s.

Has anyone else run into similar speed issues?
