Patch 2 eliminates io-wq worker creation if the worker is currently idle, and patch 3 attempts to eliminate worker creation if it's blocking on a hashed item and the next work item is also hashed to the same bucket. io_uring/io-wq.c | 50 ++++++++++++++++++++++++++++++++++++++---------- 1 file changed, 40 insertions(+), 10 deletions(-) -- Jens Axboe
