环境是:exchange 2013 CU9
近期发现后端服务器 Noderunner.exe ParserServer.exe CPU占用率高。
暂时不考虑升级CU打补丁的方案,想从其他方面优化下。
查了下资料。
First thing is to cap the memory that noderunner.exe uses, to do that edit the {Drive-Letter}:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\Runtime\1.0\noderunner.exe.config.
Locate the ‘memoryLimitMegabytes=”0″‘ value.
Change it from ZERO, (use everything) to 250 and save the file.
应该是限制内存
- Launch registry editor
- Go to path HKLM\SOFTWARE\Microsoft\ExchangeServer\V15\Search\SystemParameters
- Create a DWORD by name CtsProcessorAffinityPercentage
- Configure the value to 15 (decimal)
- Restart Exchange Search Host Controller service and Microsoft Exchange Search service on the server.
CtsProcessorAffinityPercentage 这个参数 15又是代表什么?
以上2个地方的修改,能否解决我们的问题呢?
2台后端服务器DAG,用户数规划4K~5K人,调整多少合适呢?
谢谢。
