Speed up Conda Resolving

[apeltzer]

To my knowledge, conda package resolving should speed up significantly, when we specify the way packages are pulled by a corresponding prefix, e.g.:

- conda-forge::jdk=1.X.Y

is much faster than
- jdk=1.X.Y

Maybe we should make this something that is automatically added to the environment.yml when a new repository is created to make users more aware of this?

I'd be curious to see how much of a difference this actually makes first.. 🤔

Yes, you're saying much faster, but how much faster?

I took making the Singularity container for the chipseq pipeline as an example:

Explicit paths:

real	22m35.586s
user	29m5.709s
sys	1m59.633s

Non explicit paths:

real	25m45.530s
user	31m45.949s
sys	2m36.789s

So its measurable, but not necessary in my opinion. Any thoughts on this?

Cool, thanks for checking! I think no need for now.
