Mapper is pre-configured with a maximum memory allocation of 1GB. In most cases, 1GB should be sufficient. If you work with very large mappings, you might encounter an OutOfMemory error. If this happens, increase the Mapper memory allocation.
Use this format:
<MAPPER_Install_Folder>/eclipse.exe -vmargs -Xms<MIN>m -Xmx<MAX>m
MIN is the minimum amount of RAM in megabytes, for example 512.
MAX is the maximum amount of RAM in megabytes, for example 1000.
Example Target format: IONMapper/eclipse.exe -vmargs -Xms512m -Xmx1000m
