The cache reaper does only exists in SLUB as a way to\nprovide compatibility with SLAB.

This will lead to some overlap in large\nsystems. F.e a system running at 250 HZ with 1024 processors will have 4 vm\nupdates occurring at once.\n\nHowever, the vm stats update only accesses per node information.

Enabling oprofile hurts threaded\n programs because of contention on the mmap_sem cache line.\n\n- Using an atomic_inc()/atomic_dec() on inode ref counter or mm ref counter:\n It\u0027s also a cache line ping pong on SMP. It also increases mmap_sem hold time\n because of cache misses.\n\nMost of these scalability problems come from the fact that futexes are in\none global namespace. As we use a central hash table, we must make sure\nthey are all using the same reference (given by the mm subsystem). We\nchose to force all futexes be \u0027shared\u0027. This has a cost.\n\nBut fact is POSIX defined PRIVATE and SHARED, allowing clear separation,\nand optimal performance if carefuly implemented. Time has come for linux\nto have better threading performance.\n\nThe goal is to permit new futex commands to avoid :\n - Taking the mmap_sem semaphore, conflicting with other subsystems.\n - Modifying a ref_count on mm or an inode, still conflicting with mm or fs.\n\nThis is possible because, for one process using PTHREAD_PROCESS_PRIVATE\nfutexes, we only need to distinguish futexes by their virtual address, no\nmatter the underlying mm storage is.\n\nIf glibc wants to exploit this new infrastructure, it should use new\n_PRIVATE futex subcommands for PTHREAD_PROCESS_PRIVATE futexes. And be\nprepared to fallback on old subcommands for old kernels. Using one global\nvariable with the FUTEX_PRIVATE_FLAG or 0 value should be OK.\n\nPTHREAD_PROCESS_SHARED futexes should still use the old subcommands.\n\nCompatibility with old applications is preserved, they still hit the\nscalability problems, but new applications can fly :)\n\nNote : the same SHARED futex (mapped on a file) can be used by old binaries\n*and* new binaries, because both binaries will use the old subcommands.\n\nNote : Vast majority of futexes should be using PROCESS_PRIVATE semantic,\nas this is the default semantic. Almost all applications should benefit\nof this changes (new kernel and updated libc)\n\nSome bench results on a Pentium M 1.6 GHz (SMP kernel on a UP machine)\n\n/* calling futex_wait(addr, value) with value !\u003d *addr */\n433 cycles per futex(FUTEX_WAIT) call (mixing 2 futexes)\n424 cycles per futex(FUTEX_WAIT) call (using one futex)\n334 cycles per futex(FUTEX_WAIT_PRIVATE) call (mixing 2 futexes)\n334 cycles per futex(FUTEX_WAIT_PRIVATE) call (using one futex)\nFor reference :\n187 cycles per getppid() call\n188 cycles per umask() call\n181 cycles per ni_syscall() call\n\nSigned-off-by: Eric Dumazet \u003cdada1@cosmosbay.com\u003e\nPierre Peiffer \u003cpierre.peiffer@bull.net\u003e\nCc: \"Ulrich Drepper\" \u003cdrepper@gmail.com\u003e\nCc: \"Nick Piggin\" \u003cnickpiggin@yahoo.com.au\u003e\nCc: \"Ingo Molnar\" \u003cmingo@elte.hu\u003e\nCc: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d0aa7a70bf03b9de9e995ab272293be1f7937822", "tree": "194b30b7b8374b946f166996cb99fb95eb3b7819", "parents": [ "c19384b5b296905d4988c7c684ff540a0f9d65be" ], "author": { "name": "Pierre Peiffer", "email": "pierre.peiffer@bull.net", "time": "Wed May 09 02:35:02 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed May 09 12:30:55 2007 -0700" }, "message": "futex_requeue_pi optimization\n\nThis patch provides the futex_requeue_pi functionality, which allows some\nthreads waiting on a normal futex to be requeued on the wait-queue of a\nPI-futex.\n\nThis provides an optimization, already used for (normal) futexes, to be used\nwith the PI-futexes.\n\nThis optimization is currently used by the glibc in pthread_broadcast, when\nusing \"normal\" mutexes.
