Question
Do managed databases throttle performance based on the query source?

Asked by Adam T
I’m working with a Python script that saves/updates batches of data to a MySQL database and have observed a strange and dramatic difference in performance.
When I run my Python script from GitPod, it takes about 100 seconds to update 1,000 rows in the database.
When I run the same script on a DO droplet in the same datacenter as my database, it takes <1 second to update 1,000 rows in the database.
I don’t think it’s a bandwidth issue, the gitpod has great connection: Download: 1268.49 Mbit/s Upload: 962.83 Mbit/s
The only idea I’ve come up with is that DO is throttling the performance of queries that come from an external network, but the difference in performance seems pretty extreme.

Hi there,
I believe that the DigitalOcean’s Managed MySQL Databases, typically do not deliberately throttle performance based on the query source.
There could be several other factors that might contribute to the performance difference you’re observing between running your script from GitPod and a DigitalOcean Droplet.
My guess here would be that this is due to the network latency. Even with high bandwidth, network latency can be a significant factor. The closer your application is to the database server, the lower the latency. Since your Droplet is in the same data center as your database, it benefits from very low latency, which isn’t necessarily the case with GitPod.
You can try performing a
traceroutefrom GitPod to your DigitalOcean database to check for any network bottlenecks.Also if possible, consider hosting your application closer to your database to reduce the latency.
Let me know how it goes.
Best,
Bobby
