I see around 2x performance regression when -mmlir --enable-delayed-privatization is enabled. The runtime is 90 seconds by default and when this option is disabled (-mmlir --enable-delayed-privatization=false) runtime reduces to 40 seconds.
individually, the file rhs.fppized.f90 seem to cause this performance difference.
Tried with latest sources and this issue is still there.
