- We tested opening a 229 MByte XML file on a DELL XPS 9700 with 32 GByte physical memory. You can download the test file here: 210729_DHI_BER_BTR_0001_BTB 656A_661A.rar
- Oxygen XML Editor took more than 1 minute to load the large file, while other XML Editors could load the same file in just a few seconds. Visual Studio Code and XML Spy were also slow.
- COULD NOT OPEN FILE: Some XML Editors could not open the file because it was too large.
- NO XML SUPPORT: Some XML Editors disabled XML Completion and XML Validation when the large file was opened.
