Pipelines build consistently slow since the end of July 2023

Alex Panchenko August 13, 2023



Approximately since July 30 our pipelines take much longer.

It's specially painful when when build runs without caches (when those are removed after 7 days)

We use java and gradle to manage dependencies.

A few repositories are relatively big and the build takes more than 1 hour without caches, while previously it was OK with max-time=24 minutes in one of them.

Was there any infrastructure change in that time frame or what could be a possible reason?

Hi Alex,

Do these Pipelines builds run on Atlassian infrastructure or are you using one of our self-hosted runners? You are asking about infrastructure changes so I assume they run on Atlassian infrastructure, but I would like to make sure.

Is it a certain command in your yml file that takes longer than before? Or more than one? Or does this happen in the Build setup?

You mentioned caches. Have you configured your build to download additional dependencies than before? Are there any additional tasks in your build that weren't there before?

If this concern builds running on Atlassian infrastructure, you can try debugging locally with Docker (a) a build that was previously taking less time with no cache and (b) a build that now takes longer with no cache, and observe if the times are similar to the respective Pipelines builds.

Infrastructure changes are announced here: The recent ones are the Kubernetes cluster upgrades, but I'm not sure if that would affect the duration of your builds.

If your workspace is on a paid billing plan, you can create a ticket with the support team. If we have an open support ticket, the engineer working on it will be able to access the build logs and help you with the investigation. You can create a ticket via, in "What can we help you with?" select "Technical issues and bugs" and then Bitbucket Cloud as product.

Kind regards,
