Running biglasso is much slower than before about biglasso HOT 3 CLOSED

Hmm, that's strange. seems to have something to do with your compile environment. The quick thing top of my head is gcc compiler flag. Did you set any optimization before and not now? Or using a different compiler? Honestly, I don't have too much knowledge about compiler.

This is my best guest also.
I wonder if this comes from a change in handling inlining by new compilers (I think inlining is important for the C++ matrix accessor of big.matrix objects).
I'm making some tests and search and come back to you if I find a solution to this problem.

If anyone has another idea, please let me know.

Seems to be due to the sparse matrix accessor (beta) being much slower.

I reported this issue there.
