Spring Application Advisor is running slowly or you would like to optimize the performance when applying upgrade plans
The default memory limit for Spring Application Advisor is 512mb. You may need to increase the limit for larger projects.
The more memory you configure, the better the performance should be. You can increase the memory limit using the --build-tool-jvm-args option as described in the documentation
The upcoming v1.6.0 release is also expected to significantly improve performance
