FULLTEXT Search performance

[Serge]

I have a large table with fulltext index (~180000 records, ~530Mb data, ~700Mb index).
All fulltext search queries execute too slow. How can I speed up theese queries?

mysql> select count(*) from papers where match(title,keywords) against("test");
+----------+
| count(*) |
+----------+
| 12474 |
+----------+
1 row in set (58.95 sec)

mysql> show columns from papers;
+----------+------------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+----------+------------------+------+-----+---------+----------------+
| id | int(10) unsigned | | PRI | NULL | auto_increment |
| title | varchar(255) | | MUL | | |
| keywords | text | | | | |
+----------+------------------+------+-----+---------+----------------+
3 rows in set (0.01 sec)
