[PATCH net-next] net: set SK_MEM_QUANTUM to 4096

2016-10-31 Thread Eric Dumazet
From: Eric Dumazet Systems with large pages (64KB pages for example) do not always have huge quantity of memory. A big SK_MEM_QUANTUM value leads to fewer interactions with the global counters (like tcp_memory_allocated) but might trigger memory pressure much faster, thus
