MySQL using trigger to insert into several tables parallelly - mysql

Question

I am trying to insert large amount of data (500M rows) into MySQL. I put the whole line into a first table and use an insert after trigger. Since this inserts data to 7 different tables (for normalization purposes) I was wondering whether it would be possible to do the 7 inserts at the same time. Presently I am using MySQL 5.1 which does not allow me to create more triggers on the same table. Can you suggest me something how to increase the insert speed:
CREATE TRIGGER temptable_tr AFTER INSERT ON temp
FOR EACH ROW
BEGIN
DECLARE TR_00 INT;
DECLARE TR_1G INT;
DECLARE TR_2G INT;
DECLARE TR_3G INT;
DECLARE TR_1S INT;
DECLARE TR_2S INT;
DECLARE TR_3S INT;
/* This part repeats 7 times, instead of 00, we can put 1G, 2G, 3G, 1S, 2S, 3S
Since these 7 parts insert into seven independent tables, would it possible to run them parallely?*/
BEGIN
DECLARE T_MD5_00 CHAR(32);
DECLARE SBN_00 INT;
DECLARE S_MD5_00 CHAR(32);
DECLARE SBS_MD5_00 VARCHAR(500);
SET T_MD5_00 = SELECT MD5(NEW.tr_00) FROM DUAL;
SET TR_00 = (SELECT tr_00_id FROM trans_00 WHERE trans_00_MD5 = T_MD5_00);
SET SGN_00 = REPLACE( substring(NEW.tr_00,1,((select LOCATE('>', NEW.tr_00)-1))) ,'[*:1]','[*]') ;
SET S_MD5_00 = SELECT MD5(SGN_00) FROM DUAL;
SET SBN_00 = (SELECT subs_00_id FROM substr_00 WHERE subs_00_MD5 = S_MD5_00);
IF (TR_00 IS NULL OR SBN_00 IS NULL) THEN
IF (TR_00 IS NULL) THEN
INSERT INTO trans_00(transform_00) values(NEW.tr_00);
INSERT INTO trans_00(trans_00_MD5) values(T_MD5_00);
SET TR_00 = LAST_INSERT_ID();
END IF;
IF (SBN_00 IS NULL) THEN
INSERT INTO substr_00(substruct00,subs_00_MD5) values(SGN_00,S_MD5_00);
SET SBN_00 = LAST_INSERT_ID();
END IF;
INSERT INTO tr_subs_00(tr_00_id,subs_00_id) VALUES(TR_00,SBN_00);
END IF;
END;
.....
/* At the end collect the TR_?? ids and insert them into an other table:*/
INSERT INTO pairs(tr_00_id,tr_1G_id,tr_2G_id,tr_3G_id,tr_1S_id,tr_2S_id,tr_3S_id) VALUES(TR_00,TR_1G,TR_2G,TR_3G,TR_1S,TR_2S,TR_3S
END;

Oracle has "INSERT ALL". Doesn't MySQL have it too?
