The SyncOptimize is a tool that will help you determine the best number of threads to configure for optimal throughput given the resources available on your computer and network. Before running the Sync Tool you may want to run SyncOptimize first. Once it has completed running diagnostic tests, it will return a value that you can plug into the -t parameter of the Sync Tool. If you're using Sync Tool's graphical interface, you can invoke SyncOptimize directly without having to run the command line tool. You can fire up the optimizer either by clicking "Optimize" on the final step of the setup wizard or you can access it on the Configuration tab. For more information on running the Sync Tool, go to the DuraCloud Sync Tool page.
