Frequently Asked Questions

How can I increase the performance of Astah?

The performance level of Astah depends on the RAM capacity of your machine.

Try following methods:

  • Use the latest Java environment. (See FAQ."I want to use a specific version of the JavaVM)
  • Turn off the mouse cursor tracing option.(In some environments, having this option on will make rendering slower.)
  • Tune some garbage collection settings. (When the value of INITIAL_HEAP_SIZE is set to 16m, the garbage collection does not work fully unless your computer uses more memory than 16MB)

NOTE: Do not set the value of MAXIMUM_HEAP_SIZE too small because it could cause "OutOfMemoryErrors" and Astah may not work properly.
