Hi, Otis
Thanks your reply.
yes, all cores are in same server.
* what do you consider "too long"?
just id(key) query response takes too long.
almost id(key) query response takes under 10ms.
example

* how many queries are running concurrently?
approximately 5 to 10 queries.
but queries are very complex. complex means many terms include wildcard.
* can you show some example queries?
example

q=(angiogenesis*+OR+neovascula*+OR+(vessel*+OR+vascula*)+N+(proliferat*+OR+growth*))+5N+(inhibit*+OR+prevent*+OR+treat*+OR+thera*+OR+medic*)+AND+(ibd+OR+crohn*+OR+behcet*+OR+inflammat*+2N+(bowel*+OR+intestin*+OR+colitis*+OR+enteritis*+OR+gastroenteritis*)+OR+ulcerative*+W+colitis*+OR+intestin*+W+behcet*+OR+macula*+W+degenerat*+OR+amd+OR+armd)
* how many CPU cores does your server have?
32 cores (server has 4 CPU and 8 cores in each CPU.)
128G RAM
Also, total index for all cores include 15million docs and size is 400G.
complex queries are problem??
