[Performance]: Larger ORCA output files taking ~7-8 seconds to render

[aritraroy24]

Performance Goal

Faster loading of ORCA output files

Current Behavior

CHGCAR takes ~7-8 seconds to load because of the large size of ORCA output files, and other file operations are not possible during that time.

Expected Improvement

Faster preview load of ORCA output files

Reproduction / Scenario

1. Select a {orca-output-filename}.out file to observe the preview

Scope

• Affected file type(s): ORCA .out files

• Affected area(s): Preview pane

• Frequency: always

• Load/render time: ~7-8 seconds

• CPU usage: Normal

• Memory usage: Normal

• File size / atom count / grid size: 99.5 MB, 84 atoms, N/A

• Machine specs:

  • 13th Gen Intel(R) Core(TM) i9-13900HX, 2200 Mhz, 24 Core(s), 32 Logical Processor(s)
  • 32 GB DDR5 RAM
  • Dell G16 7630

Proposed Approach

Reading the output file takes time, which affects the time to render. Maybe we can use parallel processing for rendering ORCA outputs.
