a) The board is significantly larger (90 vs 64, 40% larger)
b) Even there’s no diagonal slide moves (such as Bishops), its pieces have more limitations, been blockedblockable, Cannons have a special way to capture... The board size (90) can't fit 64-bit integer either, the number of columns 9 can't help quick devices... All may make move generators be more complex and slower
c) The search trees are usually larger. For example, when comparing Perft results at deep 7, Xiangqi number is 72 times as large
