c++ - Speed up compile time with SSD -

-

i want try speed compile-time of our c++ projects. have 3m lines of code.

of course, don't need compile every project, there lot of source files modified others, , need recompile of them (for example, when updates asn.1 source file).

i've measured compiling mid-project (that not involves source files) takes 3 minutes. know that's not much, it's boring waiting compile..

i've tried move source code ssd (an old ocz vertex 3 60 gb) that, benchmarked, it's 5 60 times faster hdd (especially in random reading/writing). anyway, compile-time same (maybe 2-3 seconds faster, should chance).

maybe moving visual studio bin ssd grant additional increment in performance?

just complete question: i've w3520 xeon @2.67 ghz , 12 gb of ddr3 ecc.

c++ compilation/linking limited processing speed, not hdd i/o. that's why you're not seeing increase in compilation speed. (moving compiler/linker binaries ssd nothing. when compile big project, compiler/linker , necessary library read memory once , stay there.)

i have seen minor speedups moving working directory ssd or ramdisk when compiling c projects (which lot less time consuming c++ projects make heavy use of templates etc), not enough make worth it.

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
