以下为调整方法和依据：
启动账号内存锁定
保证SQL Server提交内存不会被交换或空间被操作系统收缩。
The SQL Server 64-bit version uses "locked pages" to prevent the process working set (committed memory) from being paged out or trimmed by the operating system.

限制大内存大小
保留一定内存供SQL Server连接内存、其它应用、系统内存等使用。

启动帐号即时文件初始化
快速初始化数据文件空间分配，减少等待。
This should be enabled in the vast majority of cases. SQL Server 2016 lets you enable this during the SQL server installation process.

Trace Flag放到启动参数中
跟踪标志用于开启特定功能提高数据库性能。
Common trace flags that should be enabled in most cases
TF 1117 - When growing a data file, grow all files at the same time so they remain the same size, reducing allocation contention points
参考：
http://support2.microsoft.com/kb/2154845
TF 1118 - Helps alleviate allocation contention in tempdb, SQL Server allocates full extents to each database object, thereby eliminating the contention on SGAM pages (more important with older versions of SQL Server). Recommendations to reduce allocation contention in SQL Server tempdb database
参考：
http://support2.microsoft.com/kb/2154845
TF 2371 - Lowers auto update statistics threshold for large tables.
