Since the software is written in C it does not require the overhead of a Java Runtime Environment and typically requires less memory than comparable Java-based applications. However, each document is loaded fully into memory so as to parse it completely and to improve viewing and editing speed.
The memory requirement increases with the size of the document. Memory requirements are also influenced by the unlimited Undo history.
When repeatedly cutting and pasting large selections in large documents, available memory can rapidly be depleted.
