Redis Cache verry slow

[thanhtai9606]

Description

When I create an application netcore combine with Redis Cache + db mssql it request verry fast approximately 24k req/second?? But When I use redis in abp in service it very slow 1.8k req/second ?? it similary request from db?? I already debug it ok get value from redis, But it very slow???

Configuration

Net 7 and Abp Version 7.0.0

Regression?

My Code

     // var cacheDb = await _cache.GetOrAddAsync(
                //                 id, //Guid type used as the cache key
                //                 async () => ObjectMapper.Map<FileItem, FileItemDto>(await _fileManager.GetFileInfoAsync(id)),
                //                 () => new DistributedCacheEntryOptions
                //                 {
                //                     AbsoluteExpiration = DateTimeOffset.Now.AddHours(1)
                //                 }
                //             );

        var cacheDb = await _cache.GetAsync(id);
        if (cacheDb != null)
        {
            return cacheDb;
        }
        else
        {

        var data = ObjectMapper.Map<FileItem, FileItemDto>(await _fileManager.GetFileInfoAsync(id));
         await _cache.SetAsync(id,data);
            return data;

Can you share the detailed steps so I can reproduce this?

Can you share the detailed steps so I can reproduce this?

When I reduce (remove) middlewares default by abp, It better over 7k req/sec?? May be middlewares leading to performance??

[maliming]

You can check your app logs.

I already checked app logs, But no special problems??

I also met this issue. I think when too much request the method semaphoreslim.lockasync lock cache key. I deploy on cluster with load balancer
