I’m using MySql Connector .NET to load an account and transfer it to the client.
This operation is rather intensive, considering the child elements of the account to load.
In Debug mode, it takes, at most, 1 second to load the account. The average would be 500ms.
In Release mode, it takes from 1 to 4 seconds to load the account. The average would be 1500ms.
Since there is no #if DEBUG directive or the like in my code, I’m wondering where the difference is coming from.
Is there a project build option I could change? Or does it have to do with MySql Connector .NET that would have different behaviors depending on the build mode?

Comparison:
Release takes 20x the time Debug takes (average comparison).
4,404,500 / 213,000 = 20
Now the first operation is indeed longer, but in general, so are all the other times for release.
Any idea?
EDIT 2: I added even a broader tests that calculates the total time. For 50 account loads, it takes an average of 4 seconds in debugs, and 40 seconds in release. I’m starting to get quite desperate over this – it is a serious performance issue for my application. Does anyone have a guess on how to fix this?
I figured it out, I allowed unsafe code in one of my dependencies build.
I am still wondering why it is behaving like that, but I’ll have to dig this a bit more.
Thanks for all your help!
