: > how large is the performance impact of using RTTI with gcc? : : How does RTTI affect the performance? AFAIK (I havn't used RTTI too : often myself), RTTI makes the binary a little bit larger due to : additional information compiled in. Sure, evaluating RTTI data takes : cpu cycles, but if you need it, you need it, and every other way to do : that takes the same cpu cycles.
This shouldn't be an issue. I work on huge code that does massive amounts of RTTI. Sure it would be faster if it wasn't there but the code would be 50 times more complex, if it could be done at all. Ion is an amazing app, but its complexity is dwarfed by the code i'm working on (not my code... company code). If it's done right, and templates are used as much as possible, RTTI impact should not be noticable... measurable, yes, noticeable, no. Oh yeah... just have to say it... i love Ion :) Regs, Derek -- ----------------------------------------------------------- Derek Quinn Wyatt | Phone: (905) 886-7818 ext. 2313 Syndesis Engineering | Fax: (905) 886-9076 Toronto, Ontario, CAN | Email: [EMAIL PROTECTED] ----------------------------------------------------------- "He was as lame as a duck.
