@lcalviell any thoughts on this?

I doubt that there will be huge improvements by adding parallelization. The time-consuming step is creating profile for each read length, and it's not slow enough IMHO to add parallelization and all subsequent checks for its correct functionality.
Might check it in the future if there's enough demand.

@lcalviell any speed improvements would be great, as running this on a few hundred to >1K samples makes a difference, especially for cloud compute costs.

I plan on releasing a new version in the next weeks, to have a lighter html report and include output of different count tables to use directly with DESeq2 and DEXseq (more to come). Will also look at the parallelization option you mentioned.
