Want to make Liferay even faster?

If your answer is yes then vote for issue LPS-14055. As you can see Asset Publisher makes many queries to underlying database. Those are very slow queries like count(*) (needed for pager element displayed below assets lists). If you are building big portal with many AP on every page (main article list, dynamic coin slider, recommended articles etc.) you will face lots of such queries. You can of course add additional servers to database layer but that is not a solution. Only thing that will help you is optimizing AP. First thing – in every query AP uses now() for checking expiration date. That lowers database abiliti to cache queries as with every second it gets new query. Second thing is cache – those queries are not made using hibernate. Third thing is speed – why ask database using very slow IN elements in queries if you can use JOINS. There is even better solution – use LUCENE for those slooooooow COUNT queries.

So if you want your Lfierays to become even faster vote for that particular issue now.
