Slow speed result with SpeedTest test
SpeedTest selects your speed-test server based on your VPS or dedicated servers IP address GeoLocation.
At times, your VPSes physical location may NOT match with the GeoLocation (which is set on the IP address), in these cases, SpeedTest auto selects a server that may be far away from your existing VPSes physical location, which then results in a wrong/incorrect result.
Installing SpeedTest CLI on your Linux Server
Speedtest now has official apps CLI available now for running speedtests [https://www.speedtest.net/apps/cli]
CentOS / Alma Linux / RockyLinux
For installation on CentOS or Alma Linux or RockyLinux, run the following command,
curl -s https://install.speedtest.net/app/cli/install.rpm.sh | sudo bash
sudo yum install speedtest Ubuntu / Debian
For installation on Ubuntu or Debian, run the following command,
sudo apt-get install curl
curl -s https://install.speedtest.net/app/cli/install.deb.sh | sudo bash
sudo apt-get install speedtestIn this example,
VPS "LA" is located in Los Angeles, California, but when looking up in SpeedTest for servers in Los Angeles, we see the distance as 3800+ KM! This is due to the GeoLocation of the VPSes IP address.
If your VPS / Server IP is not GeoLocated correctly to the physical location of the service, we can change the IP for free to another IP which is GeoLocated correctly. GeoLocation of the VPS / Server IP does NOT affect its speed or its ping in reality!
Next, we run a test with server #18857,
[root@lax ~]# speedtest --server-id=18857
Speedtest by Ookla
Server: BAI Connect - Los Angeles, CA (id = 18857)
ISP: QuadraNet
Latency: 0.44 ms (0.08 ms jitter)
Download: 937.12 Mbps (data used: 422.4 MB )
Upload: 936.80 Mbps (data used: 421.3 MB )and with server #19230,
[root@LA71 ~]# speedtest --server-id=19230
Speedtest by Ookla
Server: Hivelocity - Los Angeles, CA (id = 19230)
ISP: QuadraNet
Latency: 0.41 ms (2.73 ms jitter)
Download: 874.93 Mbps (data used: 761.3 MB )
Upload: 798.71 Mbps (data used: 676.9 MB )
Packet Loss: 0.0%
Now, in both these cases with speedtest, we get around 930 - 790 Mbps.
Next, Let's run a wget based CacheFly speedtest file, here, we notice 94.4 MB/s (940 Mbps!),
[root@la ~]# wget -O /dev/null http://cachefly.cachefly.net/100mb.test

With earlier versions of speedtest-cli, it was possible to use a simple grep to find a list of servers for a certain region, but this is slightly different in the newer official SpeedTest CLI app,
We've listed a few server IDs for each region we provide our services out of, these IDs can be used to then apply into the below command,
speedtest --server-id=<Server-ID>Replace <Server-ID> with the ID from the list below.
For example,
[root@lax ~]# speedtest --server-id=18857

- Speedtest result also depends on the how "loaded" the test server (in above example, --server 5861 and --server 7456) also is.
- CacheFly test must be done to confirm speed as well to see if any issues exist
If you get LOW speeds with CacheFly test + SpeedTest test, please contact us right away and we will fix the issue!
