From 77335f52fca6c3cdf740baebc145d998f836fd6d Mon Sep 17 00:00:00 2001 From: Willy Tarreau Date: Mon, 11 Aug 2025 17:31:08 +0200 Subject: [PATCH] OPTIM: buffers: align the buffer pool to 64 This struct is used by memcpy() and friends, particularly during the early recv() and send(). By keeping it 64-byte aligned, we let the underlying libs/kernel use optimal operations (e.g. AVX512) for memory copies while right now it's just random (buffers are found to be equally aligned to 32 and 64 in practice). --- src/dynbuf.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/dynbuf.c b/src/dynbuf.c index 336e40d1db..12dac1a58d 100644 --- a/src/dynbuf.c +++ b/src/dynbuf.c @@ -32,7 +32,7 @@ int init_buffer() int done; int i; - pool_head_buffer = create_pool("buffer", global.tune.bufsize, MEM_F_SHARED|MEM_F_EXACT); + pool_head_buffer = create_aligned_pool("buffer", global.tune.bufsize, 64, MEM_F_SHARED|MEM_F_EXACT); if (!pool_head_buffer) return 0; -- 2.47.3
