Question

Latency Discrepancy

Hey there!

A question similar to mine has already been posted, however, I couldn’t seem to locate a resolution to my issue in that thread.

After running an online speed test a few times on my local machine, I’m averaging around 30ms of latency. Concurrently, however, the Quick Menu usage stats on my Shadow machine shows that my latency is hovering between 65-70ms. I also made sure when running the speedtest on my local machine that I selected a Dallas-based server (I’m located in Houston, and am using Shadow’s Dallas data center). I also checked task manager on my local machine and ensured that there are no other programs using bandwidth besides the Shadow application.

I can understand a few milliseconds of discrepancy here, but I’m lost as to where this extra 35-40ms is coming from. My assumption is that the routing may be taking a longer pathway than speedtest.net, but I’m not 100% sure how to test for this.

I’ll attach screenshots of both my local speedtest, and the Shadow usage stats.

Hi @OutOfFocus 

The best way to find out what is going on is to run a trace from your shadow to your IP address and from your IP address to your shadow. Then comparing paths to see if it is using different paths. You can also open a ticket and include logs from the client to see if shadow can find a better path to you. -Gelgoog.

Hello @OutOfFocus 
When using speedtest.net you are actually testing your network to the closest speedtest.net server, which is likely at a different location than the Shadow servers. Your ping to the closest speedtest server is already super high, which is why I assume that you are using a wifi connection. You should use a cable connection when using Shadow. 

Essentially: Your signal is travelling faster to the speedtest server than Shadows server, because the Servers are at different location and the travel time for your signal is shorter to the speedtest servers. 

Shadow has their own speedtest (to the shadow servers) here: https://shadow.tech/requirements/internet-speed-test
