How To: Increase performance of the tools in the Tile Cache toolset

Summary

The Tile Cache toolset contains tools to generate, manage, import, and export tile caches. These tools are capable of generating tile caches from a raster dataset, a mosaic dataset, or a map document locally on the desktop without the need for ArcGIS Server. These tools can take a significant amount of time to process and finish. Below is an option to speed up this processing time.

Procedure

These tools take advantage of the Parallel Processing Factor (Environment setting). The Parallel Processing Factor environment divides and performs operations across multiple processes.

Many modern computers include multiple-core CPUs. Spreading a geoprocessing operation across multiple processes can speed up performance by taking advantage of more than one core.

1. Launch any of the Tile Cache tools mentioned above and fill out the parameters.

2. Click the 'Environments' button.

3. Select the option 'Parallel Processing' and input a factor, for example: 50%, 75%, 100%.

The number of processes used is the specified percentage of the number of cores on the machine. For example, on a machine with four cores, a setting of 50% allocates processes to two cores.

Note:
This is all dependent on the amount of cores available on the computer. Be careful when setting this, as it uses up machine resources, if it is set to 100%, all of the cores will be dedicated to the tool's processes and other computer performance could be hindered while processing.
