      Description

      Hello,

      I'm trying to open a large file with more than 100k aligned sequences. To do so I need to tweak the allowed memory size. However tuning the options on the commandline `--jvmmemmax`, `--jvmmempc` or changing the allowed memory via the application (Tools > Preferences > Startup), or via the `.jalview_properties` file.

      To determine if the program was still failing to load my file, I attempted to lower the amount of memory allowed when loading a smaller file.
      I loaded a FASTA file (1.1GB) with 37k aligned sequences and Jalview still loads it successfully even when I limit the heap size at 300MB (jvmmemax) and the percentage at 0% (jvmmempc) (while my system tells me that Jalview takes 6.6GB), here is the extract of the `.jalview_properties` file:

      ```
      MEMORY_CUSTOMISED_SETTINGS=true
      MEMORY_JVMMEMPC=0
      MEMORY_JVMMEMMAX=300m
      ```

      That's why I have the feeling that either the options are not working properly or I'm not using them correctly.
