  • Loading Hero data lags severely

    As of a patch or two ago, any UI action that needs to load hero data lags severely. This was a sudden onset, not a gradual worsening. Maybe someone added a database join to a non-indexed key, or maybe someone's introduced nested looping structures in a service. It's possible it's a client side issue, but that seems less likely, given the symptoms (however there is certainly a severe flaw in that the entire client blocks on the service call or the processing of its response). Presuming you have even decent CI processes, you should be able to find exactly the commit that created the problem. It's incredibly annoying to have the game freeze, sometimes for multiple seconds, especially when the responsiveness of the rest of the client considerably exceeds industry norm. This is a fairly recent issue, probably with an atomic cause. It should be quick and easy to find and fix. Put a junior developer on it and let them learn from the perpetrator's mistake.
