Hello @Anonymous
I have reached out to the Logic Apps team internally and inquired about the observations that you have made. The team said that if you're experiencing this level of fluctuation on the Free Tier, it can be an expected behavior due to utility services that run under the covers could be warming up through a cold start phase which could be affecting the overall execution time.
However, since you're on the Basic tier that shouldn't have a cold-start phase, it's more likely that there's an underlying issue unique to your environment. As such, it would be best to open a support case and work with one of our support engineers who have deeper insights into your environment to troubleshoot the root cause. Does your Azure Subscription carry a support plan? If not, feel free to send me an email at azcommunity at microsoft dotcom
with subject line reading attn:murnun
and the following details included in the body of your email:
- Azure Subscription ID
- Resource Group name
- Logic Apps Name
and we can enable one-time free support on your subscription for resolving this matter. I look forward to your reply.
