From 22bb3b79290ec5970b74fa6e9eb313802d075c82 Mon Sep 17 00:00:00 2001 From: Dominique Martinet Date: Sun, 5 Sep 2021 08:29:22 +0900 Subject: [PATCH] net/9p: increase tcp max msize to 1MB Historically TCP has been limited to 64K buffers, but increasing msize provides huge performance benefits especially as latency increase so allow for bigger buffers. Ideally further improvements could change the allocation from the current contiguous chunk in slab (kmem_cache) to some scatter-gather compatible API... Note this only increases the max possible setting, not the default value.
