Re: Strange issue with django

Hi Andreas,

some tools to check performance in Perf tip on mail above, to inspect deeper.

Yeah - we have gone through the release notes - and performance wise the environment is the same but we got an extreme performance dip - we have been trying to check where we have taken performance hits - but it seems to be random and also in places where we didn't have any issues previously....

We have checked the places where we are taking hits - but my main thing is I would like to find out WHY this has happened - because it just happened spontaneously....

Regards,

Andréas

Hi Andreas,

Let try:

# Perf tip 

https://gawron.sdsu.edu/compling/course_core/python_intro/intro_lecture_files/fastpython.html

# Release note Django 3.0, DRF vs. best version

Hope this helpful.

Hi all,

We have a django backend for our application - running with DRF. This has been working perfectly since November last year. Now we have upgraded to django 3.0 and also DRF to the latest version. We also added some DB indexes. After this upgrade we now have certain endpoints that went up to 25 s loading time (from about 5 s). We have reverted most of these changes and gone through our code but still can't find where this issue is.

We even reverted back to django 2.2 and the previous version of DRF which gave us reasonable speed, but it still doesn't work correctly. 

Does anyone have any ideas what the issue might be?

Regards,

Andréas
