It doesn\u0027t\nuse any of the standard hash techniques but simply\nadds up the string and then uses power of two masking,\nwhich is both known to perform poorly.\n\nThe current x86 kconfig has over 7000 symbols.\n\nWhen I instrumented it showed that the minimum hash chain\nlength was 16 and a significant number of them was over\n30.\n\nIt didn\u0027t help that the hash table size was only 256 buckets.\n\nThis patch increases the hash table size to a larger prime\nand switches to a FNV32 hash.

The config in the powerpc merge tree is\nparticularly bad: this patch reduces the time for \u0027scripts/kconfig/conf -o\narch/powerpc/Kconfig\u0027 by a factor of 40 on a G5. That\u0027s even including the\ntime to print the config, so the speedup in the actual checking is more likely\n2 or 3 orders of magnitude.\n\nSigned-off-by: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nSigned-off-by: Roman Zippel \u003czippel@linux-m68k.org\u003e\nCc: Sam Ravnborg \u003csam@ravnborg.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "fb7f6ff614f3ead2ca41bb4a348b9ea431d95176", "tree": "4f5b3edca352f764e119b1ec57f5c76f181bb05d", "parents": [ "66d609ec8a4464b5fbe7a0723e3958b98c95991a" ], "author": { "name": "blaisorblade@yahoo.it", "email": "blaisorblade@yahoo.it", "time": "Thu Jul 28 17:56:25 2005 +0200" }, "committer": { "name": "Sam Ravnborg", "email": "sam@mars.(none)", "time": "Thu Jul 28 23:19:01 2005 +0200" }, "message": "[PATCH] kconfig: trivial cleanup\n\nReplace all menu_add_prop mimicking menu_add_prompt with the latter func.
