New features include:

• Extensive performance improvements in speed and memory use for proteomewide, label-free DIA and DDA data processing
  • If you have the hardware, Skyline should be able to use up to 100% CPU and 100% of your memory. Though we continue working on making it do more with less.
  • Performance improvements in very large DIA (6,000,000 transitions x 20 files)
  • Convergence detection in mProphet modeling and 10 iteration maximum (down from 30)
  • New --import-process-count=[num] and --import-theads=[num] arguments for SkylineRunner. The former can yield up to 10x import performance improvement on a 24-core NUMA server and 2-4x on a standard i7.
