- Just look at the Random seek figure, the smaller IDE is faster despite having
- more CPU load.
-
- Once I get to a 486/33, then you'll see comparable or even better performance
- for IDE SCSI.
- Some people posts to have the bigger file sizes but it is not to
- my liking because it is not realistic to my use.
- My prefered size is 500Kbyte, how large is xterm?
-
- If you like to see how fast your disk it, you can use bonnie to find out.
- What is important is your usual application.
- Bonnie does not represent your normal C program because it now
- does not use the default BUFSIZE, and there are attempts to minimise
- the ability for a compiler to optimize its code.
- bonnie is now more meant for people who use the same bufzie as bonnie,
- i do not know what size it is,(trying to find out, any volunteer?),
- and know how to code efficiently without relying on compilers to optimize its
- code. I'm not one of those people. I do not have time for that.
