Issue Summary

We've noticed a significant increase in response times (more than doubled from ~140ms to ~320ms) for the survey sync endpoint after upgrading from v2.7.2 to the latest version.

Image

Expected Behavior

The survey sync endpoint should maintain similar or better response times as in v2.7.2.

Other information (incl. screenshots, Formbricks version, steps to reproduce,...)

PS: the performance regression is even larger (6x increase) for the /health endpoint:

We did not make any changes to the pod resources.

@jonas-hoebenreich Sorry for the late response. We have addressed the issues and improved the performance for the client endpoints. Can you please check if this issue has been resolved with the latest version?
What version are you currently using?

Thanks for the great news! 🎉
I'll try to upgrade asap. We're still on v3.1.5, as upgrading always requires extra effort (we have to rebuild the pixel as an IIFE ourselves)

hey @jonas-hoebenreich - did you find time to check if we resolved the issue? 🤓

We also still see a performance issue in Formbricks Cloud that is connected to a 3rd party cache library that we are using in Formbricks and that is still working on full support for Nextjs 15. That's why we currently flush the cache every 15 minutes to make sure no old cache keys are building up in the cache. Not sure if this is a similar error that you are seeing but if so, please try to flush the Redis cache and check if this solves your issue for the moment.

Thank you for looking into this. The performance appears to have improved following the upgrade. I'll continue to monitor and keep you posted.
