i've started new job , inherited nightmare webforms .net 4.0 project that's going wrong in lots of places. i've got user control storing datatable in viewstate. code referencing columns throughout code index number making totally unreadable. know can reference columns name make more readable i'd prefer break out list. the previous developer storing list in viewstate because changes can't persisted database, read in data, sales people can make modifications pricing , information pushed xml format generate sales order form in pdf. need mechanism storing temporarily. if had luxury of starting scratch i'd pull data down in json , client side don't have luxury yet. it's been long, long time since worked datatables , i'm pretty sure it's not placing in viewstate, correct? kind of load placing on viewstate; we're looking @ 44 columns , around 25 rows. :s secondly, if there big difference between placing list in viewstate opposed datat...

i wonder if it's idea keep using int (which 32 bit on both x86 , x86_64) on 64 bit programs variables have nothing special , not need span 2^64, iteration counters, or if it's better use size_t matches word size of cpu. for sure if keep using int save half of memory, , mean speaking cpu cache, don't know if on 64 bit machine every 32 bit number has extended 64 bit before use. edit: i've ran test program of mine (see self answer , still keep janneb's accepted though because good). turns out there significant performance improvement. for array indices , pointer arithmetic, types of same size pointer (typically, size_t , ptrdiff_t) can better, avoid need 0 or sign extend register. consider float onei(float *a, int n) { return a[n]; } float oneu(float *a, unsigned n) { return a[n]; } float onep(float *a, ptrdiff_t n) { return a[n]; } float ones(float *a, size_t n) { return a[n]; } with gcc 4.4 -o2 on x86_64 following asm generated: ...
