| |
Hi.
I've tried running a few bonnie++ benchmarks but I'm not understaning how to tune the options. Nor can I figure out much form the output because I don't understand what the options do... I went to the programs homepage but theres no info on this.
This is the string I used to measure my single HD throughput. This because I want to compare it with the RAID system I will soon implement.
bonnie++ -d /mnt/download/hd_tests/ -s:1024:32k -m Gaia -r 512 -x 2 -u antonio -f | bon_csv2txt
And this is the output:
Version 1.02b ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks-- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP Gaia 1G:32k 26895 41 10177 13 25450 16 145.5 3 Gaia 1G:32k 26636 42 9849 12 25920 17 146.4 3 ------Sequential Create------ --------Random Create-------- -Create-- --Read--- -Delete-- -Create-- --Read--- -Delete-- files:max:min /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP Gaia 16 340 97 +++++ +++ 16450 79 340 97 +++++ +++ 1861 96 Gaia 16 267 77 +++++ +++ 12301 62 240 69 +++++ +++ 1339 69
----------------end of first test-------------------
If my filesys is ext3 with 4K blocks must I use a 4K chunk-size? Is this what the chunk-size is for?? Why is the "sequential create --> read" empty? I would like to understand how fast is my HD in reading but can't get it from the above...
Would be greatfull if someone could help me with this stuff. A nice link to some www page would do fine. I tried with google but can't find much that is helpfull.
