Recently i had to grow the capacity of my NAS. The NAS is running Debian and RAID is powered by md. I had attached 3 hard drives to it which were working as RAID5 array. Now i could write about how to grow a RAID, but you will be able to read that on more than enough other websites. I would rather share a benchmark i have created using Bonnie++. Let me show you the effects of changing the amount of hard drive on the read and write performance.
Last week i posted an article about the application Preload and how you can use it to tune the startup of applications impressively. While researching on Preload i found another way for tuning my system even more with a similar technique. Lets talk about Prelink:
This daemon creates statistics of your process and application usage. And that is all that is need for speeding up the start of applications by about 50%.
Preload is one of the applications i usually install right after setting up a new desktop distribution. Die effect on the response time of a system is clearly observable. Everything goes faster an makes much more fun .
