Upgrade to 3.4.13 enterprise with lucene search and association performance issue

[qsdmv]

Recently we have upgraded our alfresco enterprise edition (3.4.8) to 3.4.13. But we experienced very serious performance issue. When we do search (lucene type of search), simply type in query from "node browser" with lucene selected. It almost takes 30 seconds to 2 minutes. If you go to document detail page to search association, it also takes long time. By digging down, it is basically related to lucene search. We did upgrade a few of times. We set indexing mode as "AUTO", not see any problem for indexing. What does cause lucene search performance issue. I am trying to do FULL INDEX but failed due to OutOfMemory. But I don't think that it is right solution for production environment. If someone has similar situation and has solution, would you please share with us? We are prepared for production upgrade, had ticket couple of weeks ago but still not get right answer from alfresco. Thanks in advance.

Have you applied latest service pack for particular version which you are using?
Also are having any particular error in logs?
If your indexes are corrupted it will not give you result at all So, let me ask you this are you facing this performance degradation in all other functions as well?
How much content you have?

I don't see any particular error in logs. I don't see indexes corrupted since I got results as expected. Other than lucene search issue, I don't see any other issues. I upgrade by following upgrade instruction. I am not sure about what you said: "Have you applied latest or Have you applied latest service pack for particular version which you are using". Would you please specify? Thanks for your help.

Service pack contains most of the major bug fix for particular version. So, it is recommended to apply latest service pack of version which you are using to get rid of any potential bug in that version.To upgrade to the latest version, first apply the latest service pack for your current version, then upgrade to the latest version (including service pack)

alfresco.war file in 3.4.13 already includes major bug fix. When you do upgrade, it automatically gets everything. There is no such thing called latest service pack. You don't need to think it separately. This is why I got confusion. Sorry about that. Thanks.
