[GitHub] [incubator-doris] xinyiZzz commented on pull request #9521: [improvement][performance] improve lru cache resize performance and memory usage

URL: https://github.com/apache/incubator-doris/pull/9521#issuecomment-1124604826

   Hi @gaodayue 
   Please provide test results to demonstrate the performance and memory usage benefits of singly linked list, especially at high concurrency.
   
   The lru cache is used globally in Doris, and the resize is very low frequency. It will only be resized frequently when the BE is cold started.
