| * Two "real" changes:Keith Bostic2015-01-231-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't count pages evicted by a worker thread as an "application thread" eviction; add a new statistic to distinguish between the server itself evicting pages and the eviction worker threads evicting. Don't increment the eviction counters unless we find a page to evict, __evict_lru_pages() gets called a huge number of times in any workload where eviction is happening. Discussion: The "is_app" flag is being used for a few purposes: - if we should perform the "oldest transaction in the system" test, - if the evictor thread is the eviction server, - if the "eviction by an application thread" counter should be incremented, - if the session's split generation can be non-zero after eviction. Move the "oldest transaction in the system" test outside of the eviction code, and do that test before trying to evict a page (this required moving __wt_txn_am_oldest() from include/txn.i (an inlined function) into txn/txn.c (a real function). Replace the "is_app" flag with an "is_server" flag to distinguish between the eviction server and eviction work threads (we can distinguish between application threads and worker/server threads using the WT_SESSION_INTERNAL flag in the WT_SESSION handle). Reference SERVER-16997, SERVER-17020.
