| Summary | 0027008: Thread stalling issue (with Dump Threads Run) | ||||
| Description | Around mid-late game, started having things stall out with an alert about various background processes not updating for 4-15 seconds. Things would resume for a moment and then stop again. I ran the debug process logger and process killer and copied the log file. Quitting and reloading save got things back to normal. | ||||

Okay, this is very interesting. I think that this is not at all the sort of thing we've been seeing elsewhere. Essentially, the core problem here is that the central dictionary of things-that-have died (most notably shots in this case) is getting monstrously huge, and taking a long time to parse. I should be able to mitigate this a lot by simply making it not really track that sort of thing for shots (wow does it not matter), since that's the thing that grows fastest. But then also for the ships, I think I can basically make it just clear out old entries. I had wondered a while back if this would be needed, but I didn't want to borrow trouble if it didn't seem to be an issue. Not it's clearly an issue. |

Thank you! This should be fixed now: * Added a notable performance improvement for games that have been running for a long while without reloading or closing the game or going back to the main menu, especially when there are a lot of shots being fired. ** As part of this, also adjusted how our central dictionaries are handled for shots, ships, and wormholes, and thus have removed any chance that a deadlock was resulting from them. ** Thanks to Matt Dyer for the "thread stalling" report, which was the performance issue in question. Without the thread dump from him, this would never have been found! |
