There is more to the late 2008 macbook RAM upgrade than meets the eye

http://blog.macsales.com/9102-secret-firmware-lets-late-08-macbooks-use-8gb I read this and decided to upgrade the RAM on my macbook - late 2008 model -macbook 5,1. I first searched for the correct RAM online and saw this: http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3 This is memory it recommends: 8.0GB  OWC Memory Upgrade 2 x 4.0GB PC8500 DDR3 1066MHz 204 Pin Now, this costs $89.88.

When you have lot of money then it is easy to simply throw money at the problem so that even when nobody is using the service it runs say 2 small or 2 medium roles. Sometimes we can try to justify this saying that the application really needs 2 small roles just for something like caching. It all adds up quickly when the main app needs another 2 roles and a service is another 2 roles. I have gone from using 5 roles to just 3 roles at steady state. And I get better performance also. I am currently using 2 co-located roles which have caching + web. This makes the web role faster because the cache is in its own memory. This is faster than using dedicated roles and even trying local cache along with it. The slowest is shared caching where they provide the service. This is followed by dedicate...
