jaymc Posted September 25, 2007 Share Posted September 25, 2007 I'm wondering if its worth me upgrading mysql from 4.1 to version 5 In practice do servers generally perform better by simple upgrading to mysql 5, or does it depend on certain things... For instance if version 5 better handles indexes faster or what ever.. Just trying to gether info before I decide whether to do a full upgrade and go live Thanks Link to comment https://forums.phpfreaks.com/topic/70639-from-41-to-5/ Share on other sites More sharing options...

jaymc Posted September 25, 2007 Author Share Posted September 25, 2007 Haha! What do you mean everythnig comes at a price? Yeh my fascination is due to having plans to maximize an already very busy website. I want to know as much as I can to prevent the possibility of hitting bottle knecks in the future If I can create a system capable of 5X what I expect I can sit back and let the system run itself and the members build up. Ive paid the price in the past for not designing my systems so I want to get it spot on So yeh, elaborate on the price..

fenway Posted September 25, 2007 Share Posted September 25, 2007 You optimize one thing at the expense of another, always. Link to comment https://forums.phpfreaks.com/topic/70639-from-41-to-5/#findComment-355183 Share on other sites More sharing options...

fenway Posted September 25, 2007 Share Posted September 25, 2007 What are you suggesting will suffer? Whatever you're not optimizing... for example, mysql 5 has merge indices, so that you can use multiple keys on a single table. Sounds great, right? Well what about all those queries where this would be disastrous? Like almost every old query you've ever written? No so simple.
