To improve performance, use a faster disk drive, move files to a second disk, or add disks to a RAID array. Adjust the memory allocated to the SQL server. Keep an eye on the SQLServer:Buffer Manager: Page reads/sec and SQL Server:Buffer Manager: Page writes/sec parameters. Store ...
The main cause for reduced full-text indexing performance is hardware-resource limits: If CPU usage by the MSFTESQL service and SQL Server are close to 100 percent, the CPU is the bottleneck. If the average disk-waiting queue length is more than two times the number of disk heads, there ...
