问题描述
你好，
我们的Search应用程序的搜索索引中有800万个项目，我们在生产环境中遇到了搜索爬网性能问题，并且爬网需要花费很长时间才能完成，并且导致SQL端的CPU和RAM使用率很高.
Our Search application have 8 million items in search index and we are getting search crawl performance issues in production environments and the crawls are taking long time to complete and causing heavy cpu and ram usage on SQL side.
当我们检查爬网运行状况报告时，我们注意到了爬网队列数据，它显示事务队列计数非常高.
When we checked the crawl health reports, we noticed crawl queue data and it showing the transactions queue count is very high.
请检查以下数据.
此问题的根本原因是什么.
What could be the root cause for this issues.
推荐答案
您使用的爬网类型是什么?尝试使用仅对新项目和更新项目进行爬网的增量爬网.
What’s the type of crawl you used? Try to use incremental crawl which only crawl the new and updated items.
添加一些爬网规则以排除不必要的项目，然后再次检查.
Add some crawl rules to exclude unnecessary items and check again.
