why major_compaction does more performance consumption than minor_compaction ?

hello everyone! Differenct between them: 1、minor_compact will select best storeFiles to compact。 2、major_compact will select all storeFiles to compact and do some clean work。 RegionServer holds only one compactSplitThread ，and only one compact task run ! 3、The compaction task just scans all
