Quartus prime pro Window 10 runs 6x faster than on linux red hat 7

Quartus prime pro Window 10 runs 6x faster than on linux red hat 7

Using quartus 20.2, the all place and route takes 6h under linux (dedicated big machine with lot's of mem)

and runs in 1h using Quartus 20.2 under Windows 10 (SSD, 32 GB ram, local machine).

Is that known that linux version is crawling?

Or is it due to the IT server infrastructure for linux version?

Original run is under Linux, then I create a qar file (export) and import the .qar under windows 10/quartus, so the design and SDC are 100% the same

      I did test using another project on Arria 10,

      it is also the case, 5x faster on Windows 10 using the quartus synthesis tool (in my provious project synplify was used to create the vqm netlist).

      Any clue Intel?

        It turned out that the LSF system was making quartus only be able to use 1 core of the CPU...

        Extending to more core speeds up quartus and reaches same speed than under windows 10.
