Hi @Imran Nawaz,
Adding a second search server to your SharePoint 2019 on-premises farm can indeed help reduce crawl times for site collections. With two search servers, the workload can be distributed, allowing for more efficient crawling. This means that the overall time taken to crawl the content should decrease, as both servers can work simultaneously on different parts of the content.
Additionally, having a second server can improve user experience. When a crawl is running on a single server, it can consume significant resources, leading to slower site load times and potential display issues for users. By distributing the load across two servers, you can alleviate some of the resource contention, which should help maintain better performance and responsiveness during crawls.
