Jing, I think I have an explanation for why advanced search in the LTER skin would be faster at metacat.lternet.edu than at knb.ecoinformatics.org. The key is the indexPaths property in the build.properties file. I have fine-tuned the indexPaths setting at LTER such that all EML fields searched by the advanced search code are included in the indexPaths list. When this is not the case, the advanced search does perform extremely slow (as you are seeing at knb).
Below is the setting that we are using at LTER. If you cross-reference the values used in metacat.lternet.edu with those at knb.ecoinformatics.org, you will probably find a number of fields that were added to the LTER setting (and perhaps some fields that are used in KNB but not at LTER).

Currently the KNB has a link to the advanced search. The advanced search is too slow and does not have very many advanced search options. I do not think it is working with the improvements that have been made for query caching.

the LTER skins advanced search on the KNB metacat has more options but the search is very slow http://knb.ecoinformatics.org/knb/style/skins/lter/index_advancedsearch.jsp
However the advanced search on the LTER metacat (not knb) appears to be working fine. Maybe their solution will help with updating our advanced search. I'm not sure why the http://metacat.lternet.edu advanced search is working well and the http://knb.ecoinformatics.org metacat is so slow.
