Please share, if 2k qps for loaded drupal for 3k concurrent users is OK. My server (2x2G Xeon 1G Ram) goes mad of such load and once a day just hanged within second (even did not write err_log). What can it be? Might it be core problem?
This isn't a software solution, but bumping up your RAM could buy you a lot. I don't know what kind of caching you're doing, but more ram gives you room for (more) query_cache, which is a little thing that can buy you a lot. IME, once MySQL runs out of ram, the read/write temps can bring you to a crawl, and then the queries just pile up. RAM is cheap. Even after you optimize your code, that headroom can help performance.
