it seems lot of code in boost compiler-specific workarounds or different paths different compilers (especially in components mpl). build time increases lot when use boost, when try hide big parts behind compiler-firewalls (pimpl) or use precompiled headers. is there way pre-process boost headers 1 compiler i'm using? suspect makes headers (significantly?) smaller have impact. has ever tested whether give speed improvements? no idea whether matters actual answer, i'm using visual studio 2010 primarily. if use precompiled headers, preprocessing headers on steroids. if pch won't make difference, there nothing can will. the compile time comes excessive including or complex template instantiations, not size or complexity of preprocessor.

(int = 0; < len; ++i){ int v = arr[i]; int j = i; saves computing i-1 2 times , ++i faster i++. not sure length thing (could save offset addition when accessing class member). 4,5) for (/*declared j outside loop*/; j != 0; --j) { j!=0 should faster j>0 (really don't expect much) , --j faster j--. well of them may platform dependent , may make no difference @ all.

hello use malloc() generate buffer buffer char* buffer = (char*)malloc(chunksize+1); (k = 0; k < chunksize; k++) { buffer[k] = (char) (j+k); } however, in debugger can see buffer[3] example char wrote in, buffer buffer empty(a lot of spaces). second time write stuff in buffer after free(buffer), shows the content wrote first time, , overwrite it. can tell me why? thank you!! one problem might try print char buffer printf or equivalent? missing assign buffer[chunksize] = 0; so buffer not terminated. may have behind that, e.g '\r' . if on other hand buffer doesn't represent string you, better use different base type, unsigned char .

so, i'm using api little unfriendly in ways. basically, api creates resource can fetched later. resource may or may not still exist when go fetch later. to fetch created resource, have use result guid so: string resultkey = "12345"; persistedresult r = mfactory.getpersistedresult(resultkey); now, tricky thing here getpersistedresult not throw exception when called invalid guid... persistedresult lazy loader , fail when 1 of methods called (causing object load itself). so, try , determine whether or not resource valid, i'm doing following: persistedresult r = null; if (!stringutils.isempty(resultkey)) { try { r = mfactory.getpersistedresult(resultkey); r.getresultcount(); // triggers exception if result key invalid. } catch (exception e) { // handle exception } } is call getresultcount @ risk of being optimized out because i'm not using value? calling method on persistedresult goes external database, in...
