I have tried everything to speed up the seach engine, but it is still to slow. When the index table seach engine is on it takes around 2 sec before something happen. When the general engine is on , it takes up 10 sec.
Please help
2 seconds is actually not a bad performance, but it depends on how many items you have, as well as the server performance. I recommend trying these suggestions from the documentation. It should maximize the performance, and then it only depends on the server response time.
