I am often asked how DataView compares to Listbox in terms of adding rows.

Here’s a comparison adding 100,000 rows of 3 columns:

macOS 64bit:
– ListBox: 3 Seconds
– DataView: 3 Seconds

Windows8 64bit:
– ListBox: 43 Seconds
– DataView: 2 Seconds

Linux Mint 64bit:
– Listbox: 2 Seconds
– DataView: 3 Seconds

Of course DataView also includes some on-demand options allowing a list of 5,000,000+ rows to load instantly. It only depends on the speed of your back-end.
