6498 Enables more than one large query compilation to gain access to the large gateway when there's sufficient memory available. This trace flag can be used to keep memory usage for the compilation of incoming queries under control, avoiding compilation waits for concurrent large queries. It's ...
MaxQueueThreads Specifies the number of threads used by the Report Server Windows service for concurrent processing of subscriptions and notifications. Valid values range from 0 to maximum integer. The default is 0. If you choose 0, the report server determines the maximum number of threads. If ...
For example, processing a query in parallel typically uses more resources than processing it serially, but completes the query faster. The SQL Server Query Optimizer will use a parallel execution plan to return results if the load on the server won't be adversely affected....
The transaction commit processing does not wait for log IO to finish and return control to the client. Concurrent transactions are less likely to contend for log IO; instead, the log buffer can be flushed to disk in larger chunks, reducing contention, and increasing throughput. Note You may ...

the rebuild or reorganize operation can degrade performance of other workloads due to resource contention. For example, bulk data loads can become slower because transaction log I/O is at 100% due to a concurrent index rebuild. In Azure SQL Managed Instance, this impact can be reduc...
