Description

Nick reported that ~1 GB was used up by a 4 GB file loaded as a file-based back end. A big part of that is the memory of the boxes, which for a 3D MDBox was 280 bytes at the start.

Minimize memory use of IMDBox, MDBox, MDGridBox as much as possible.

Refs #3122: Added compiler directive to avoid caching centroids for all boxes - should save some memory at the cost of slower centroiding/peak finding.

Refs #3492: Reduced the size of MDBox'es some more, about 12 bytes per box.

  • Resolution set to fixed

Centroiding peaks must be slower now, need to compare performance vs memory use and make a choice there.
