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.

      12 cores usage, memory reservation of 48 GB with a CPU factor above 3.4 GHz (machine with CPU core faster than 3.4 GHz will be used).
