Some of the basics when you want to take your packages to the next level of scalability include knowing where your performance hits are, and choosing the right task to handle your data processing. When it comes to evaluating performance, the primary areas are identifying the control flow task durations and checking memory utilization. However, before diving into these areas, the first thing to look at is your SSIS service.
12.1.1. SSIS Service Status
The first thing you should check when encountering a performance problem is whether the SSIS service is started and set up to auto-start. The service provides some core functionality, such as enumerating and caching the component. By doing this, packages load faster and start up faster. The service name is SQL Server Integration Services, which uses the executable MsDTSSrvr.exe. To check the status of the SSIS service, open the SQL Server Configuration Manager and browse the SQL Server 2005 Services container, as Figure 12-1 shows.
