I use ArcMap 10.1. I have a map with many Mosaic and Raster layers. They are stored in many gdb-s. I publish this map with option "Create tiles on demand".
But this tiles are created very slowly (may be 2 minutes!!!). How increase the number of processes in arcgis server, which created this cache?
P.S. I know that ArcMap use only one сore. But maybe ArcGis server can use more cores?
Update
Thanks. I have the same problem. I set 24 cores. But CPU usages between 10-14%

There are several overlapping issues here. ArcGIS Desktop is single-threaded, but can make use of a multi-core machine because it can then get the exclusive use of one core. Unless there's a Direct Connect connection to an enterprise geodatabase, in which case, each connection will be run as an additional thread.
ArcGIS Server supports multiple cores innately due the "server and service" architecture (it also supports multi-threaded access to Direct Connect geodatabases). The number of threads dedicated to any one service is controlled by the service properties (maximum and minimum number of instances):
I'll generally increase the maximum number of instances before building a cache, especially when it appears that it will take several days to build out all fourteen pyramid levels.
The "Create tiles on demand" option will actually reduce core the utilization, since it tells AGS to wait until maps are requested before populating the cache.
In order to be in compliance with licensing, you should have licensed additional bundles for your 24-core server.
Finally, it's possible that you are limited due to concurrent access to a slow I/O resource. This is probably something to discuss with Tech Support.
