Improving performance at scale

Improving performance at scale Over the past two months we received reports of slow performance affecting some of the larger Linear workspaces. We looked into the issues, and even made some changes to speed up the app, but determined that fixing the problem would require deeper work. Over the last couple of weeks, we have been heads down implementing fixes and planning larger changes to Linear's architecture to support the long term scalability of the service. Unfortunately what makes Linear extremely fast for most users can also make it slow for others if we scale faster than expected, which we did. This stems from technical architecture choices we made to build Linear and their trade-offs. This didn't come as a surprise to us and we anticipated having to make changes sometime in the future, but not so soon and especially not after customers hit performance issues. We do our best to work on these issues before they can become a problem for an end-user. This week we shared a pre-mortem that explains Linear's architecture, the performance issues these customers were hitting, and the steps we're taking in the near and short term to address them. While your workspace might not be affected, we wanted to share the document with all of you as we work through these challenges. If you hit performance issues, now or in the future, we'd like you to reach out so that we can fix them. The good news is that thanks to this work, Linear has gotten significantly faster for all users in the past two weeks. We consider speed a core feature of the product and will continue to treat it as a top priority as we scale.
