[Koha] Please advice how to improve our search issue

hello all, Our Koha response time is too slow. We have 217062 biblio records, 289026 items, and with zebra index. When I use keyword to search, it spent almost 30s for the slowest one, the averige is 10s. Is there anyone who has ever met this situation and solved the issue? OS: Ubuntu 12.04 Koha version: 3.06.02.000 Any help. Thought, direction would be greatly appreciated! Thank you.
