Full Scans/sec Number of unrestricted full scans per second. These can be either base-table or full-index scans. Index Searches/sec Number of index searches per second. These are used to start a range scan, reposition a range scan, revalidate a scan point, fetch a single index record, an...

FreeSpace Scans/sec Number of scans per second that were initiated to search for free space in which to insert a new record fragment. Full Scans/sec Number of unrestricted full scans per second, which can be either base-table or full-index scans. Index Searches/sec Number of index searches...
After you find the query that causes lock escalation, look for opportunities to create new indexes or to add columns to an existing index to remove full index or table scans and to maximize the efficiency of index seeks. Consider using the Database Engine Tuning Advisor to perform an ...
This cost value is decremented each time the Resource Monitor scans it. When a request requires cache space, the pages are flushed from memory based upon the cost associated to each page; pages with the lowest values are the first to be flushed. The Resource Monitor's activity can be ...
Use the SQL Server:Latches object and associated counters in Performance Monitor to gather information about SuperLatches, including the number of SuperLatches, SuperLatch promotions per second, and SuperLatch demotions per second. For more information about the SQL Server:Latches object and ...
The baseline index for memory-optimized tables is the NONCLUSTERED index, which supports point lookups (index seek on equality predicate), range scans (index seek in inequality predicate), full index scans, and ordered scans. In addition, NONCLUSTERED indexes support searching on leading columns of...
Figure 2: Latency buildup with default scan job parameters (maxscans=10, maxtrans=500, and pollinginterval=5) In practice, we found that with the ISV application workload about 670 transactions per second were processed, with drops when very big transactions needed to be processed. As a resu...
Serverless is a compute tier for single databases in Azure SQL Database that automatically scales compute based on workload demand and bills for the amount of compute used per second. The serverless compute tier also automatically pauses databases during inactive periods when only storage is billed ...
If theSqlservr.exeprocess is causing high CPU usage, by far, the most common reason is SQL Server queries that perform table or index scans, followed by sort, hash operations and loops (nested loop operator or WHILE (T-SQL)). To get an idea of how much CPU the queries are currently ...
