Pushing the envelope of build performance
-J option
Does SparkBuild support the -J option (from gmake)?
As SparkBuild does not have parallelization, I was wondering if I could use this option to get some acceleration.

SparkBuild does not currently support the -J flag.

"Currently"? does it mean it's on the ER list?

Adding support for the -J flag is something we're considering, but haven't decided on yet. For most subbuilds, parallelization may not improve build time significantly (since you're likely to be building mostly a serial chain) but for larger builds it can of course be helpful (in the same way that ElectricAccelerator is!)
