When we are having many (~100) requests simultaneously, we frequently get this timeout exception when trying to read c:Volo.Abp.LanguageManagement.Texts,k:App:App_zh-Hans from redis, and it seems to be the culprit which drags the server performance drastically. Can you help me to understand what LanguageManagement is doing here? How can we optimize for this situation?
- ABP Framework version: v4.3.2
- UI type: Blazor
- DB provider: EF Core
- Tiered (MVC) or Identity Server Separated (Angular): yes

hi
Did you output the logs to the console? if yes, You can disable it.
It's Redis server v=6.2.4 running on Ubuntu server 20.04.
Does the server's CPU/memory and network bandwidth meet your request?

Sorry but I don't quite get it, what's the point of disabling the console log output?

It's running on an internal bare metal test server on our intranet, not really fancy on the specs (Xeon E2224 + 24GB RAM) so I guess it could be somewhat CPU-bound when processing a lot of requests. However we'd like to understand why LanguageManagement and Redis are involved here (which is of course not related to the business logic of these requests), and if possible, how can we cut them off to increase the server throughput.

This is not relevant to our case, our service is running on a Ubuntu machine, it does not have a console window and we absolutely won't click to freeze it. The screenshot you see is from an SSH session.
You can remove the
DynamicLocalizationResourceContributor.Configure<AbpLocalizationOptions>(options => { options.GlobalContributors.Remove DynamicLocalizationResourceContributor });Thanks, we'll have a try.
