[!INCLUDE[ssISnoversion](../../includes/ssisnoversion-md.md)] installs a set of performance counters that you can use to monitor the performance of the data flow engine. For example, you can watch the "Buffers spooled" counter to determine whether data buffers are being written to disk temporarily while a package is running. This swapping reduces performance and indicates that the computer has insufficient memory.

Synchronization Manager allows you to use the Interactive Resolver for merge subscriptions. Typically, conflicts detected during synchronization are resolved automatically, but if interactive resolution is enabled, conflicts can be resolved by a user during synchronization. If a synchronization is performed outside of Windows Synchronization Manager (as a scheduled synchronization or an on demand synchronization in [!INCLUDE[ssManStudioFull](../../includes/ssmanstudiofull-md.md)] or Replication Monitor), conflicts are resolved automatically without user intervention, according to the resolver specified for the article.
