increasing the SNAP RAM ,For the SNAP Desktop application, you can increase the amount of memory available to SNAP.
In the ‘etc’ folder of the SNAP installation directory, you’ll find a file named snap.conf. Open it in a text editor.
There is the line which starts with ‘default_options=’
In this line you’ll find an option like -J-Xmx5G . Increase the value. You could use something like -J-Xmx13G , if you have enough memory in your computer. By default, it is set to ~75% of the maximum value. This is usually a good choice.
Also you could set the cache size ,
