Why is my new scaled droplet (16GB RAM - 8 vCPUs) is 4 times slower than the old one?

Hi there,

In general, scaling up your Droplet should generally result in better performance. However in some cases, right after a restart of your server, all of the cache would have been cleared, which could result in a temporary poor performance while all the cache rebuilds.

Can you share here a bit more insights on the following:

• How exactly are you measuring the performance?
• What is your exact resource utilization? Sometimes the bottleneck could be the application itself rather than the size of the server.
• What is your exact tech stack? In most cases, it could be just a matter of tweaking a specific service, like MySQL for example.
• Is your new Droplet in the same region as the old one?
• Is your new Droplet is on a shared CPU plan compared to a dedicated CPU plan of your old droplet?

The more information that you could share the better.

But in general, I would recommend checking your resource utilization and see what processes are utilizing the most resources:

That way you could pin point if the problem is caused by a specific process or service.

Also, if you are using MySQL follow the steps here on how to tweak it for better performance:

Heya @56bd8300516443db8f6e925c6721b4,

How is it slower? Is your website slower or generally your Droplet is experiencing high load?

Usually, when the Website is slower there is a need of mix of optimizations - Server Side and Application Wide. If you provide more specifics on how are you measuring it, in what regards are you seeing it being slower, I can provide with a more pinpoint answer on how to approach and resolve this.

Heya, @56bd8300516443db8f6e925c6721b4

Whenever you upgrade the droplet the performance should usually improve, in case there is a slower response or poor performance you can look into tweaking the configuration of certain service that causes load or is consuming large amount of the droplet’s resources.

Looking at the provided output from the htop command Bobby is correct about the MySQL configuration and indeed needs a tweak or two to improve the performance. Using tools like MySQL Tunner can help you to adjust the MySQL values to resolve the issue here.

Hope that this helps!
