I implemented ngx_uring_module using Linux io_uring API to improve performance of Nginx for Linux by minimizing system calls. There are performance improvements in both request/sec and average latency. The result is located at https://github.com/dachshu/nginx. However, there are some places that uses local variable buffer(stack) to recv and send data. To do asynchronous IO, recv and send buffers should be located at safe memory(like heap, data). Therefore it is needed to make these codes to use allocated memory from memory pool when using asynchronous IO. Also I am working on improve performance of Nginx for Windows using Registered IO and IOCP. diff -r 09dfe4a92414 -r d7420a5777b6 auto/os/linux --- a/auto/os/linux Mon Nov 23 11:01:36 2020 +0000 +++ b/auto/os/linux Mon Nov 23 11:03:35 2020 +0000 @@ -89,6 +89,30 @@ fi +# io_uring + +ngx_feature="uring" +ngx_feature_name="NGX_HAVE_URING" +ngx_feature_run=yes +ngx_feature_incs="#include <liburing.h>" +ngx_feature_path="-I src/liburing/src/include/" +ngx_feature_libs="-L src/liburing/src/ -luring" +ngx_feature_test="struct io_uring ring; + struct io_uring_params params; + if (io_uring_queue_init_params(32768, &ring, ¶ms) < 0) return 1; + if (!(params.features & IORING_FEAT_FAST_POLL)) return 1;" +. auto/feature + +if [ $ngx_found = yes ]; then + have=NGX_HAVE_CLEAR_EVENT . auto/have + CORE_SRCS="$CORE_SRCS $URING_SRCS" + CORE_INCS="$CORE_INCS $ngx_feature_path" + CORE_LIBS="$CORE_LIBS $ngx_feature_libs" + EVENT_MODULES="$EVENT_MODULES $URING_MODULE" + EVENT_FOUND=YES +fi + + # O_PATH and AT_EMPTY_PATH were introduced in 2.6.39, glibc 2.14 ngx_feature="O_PATH" diff -r 09dfe4a92414 -r d7420a5777b6 auto/sources --- a/auto/sources Mon Nov 23 11:01:36 2020 +0000 +++ b/auto/sources Mon Nov 23 11:03:35 2020 +0000 @@ -120,6 +120,9 @@ EPOLL_MODULE=ngx_epoll_module EPOLL_SRCS=src/event/modules/ngx_epoll_module.c +URING_MODULE=ngx_uring_module +URING_SRCS=src/event/modules/ngx_uring_module.c + IOCP_MODULE=ngx_iocp_module IOCP_SRCS=src/event/modules/ngx_iocp_module.c
