关联查询一张小表。对性能有影响吗（mysql）

SELECT
	dfm.id,
	dfm.member_code,
	dfm.member_name,
	dfm.recommend_code,
	dfm.member_rank,
	dfm.create_time,
	dfm.account,
	dfm.have_account,
	dfm.member_img,
	dfmr.rank_name,
	dfmr.grade_commission_ratio,
	dfm1.member_name AS recommendName
FROM
	d_fx_member dfm
LEFT JOIN d_fx_member_rank dfmr ON dfm.member_rank = dfmr.rank
LEFT JOIN d_fx_member dfm1 ON dfm.recommend_code = dfm1.member_code
WHERE
	dfm.member_code = ‘zqy04‘
