What is the fairest unit to determine the disk usage (except the total storage usage e.g. in GB)? IOPS? Bytes read / write? Bytes transferred over network (would be equal to Bytes r/w)? Other? And ...
All other things being equal, how would a storage array's IOPS performance change if one used larger disks. For example, take an array with 10 X 100GB disks. Measure IOPS for sequential 256kb block ...
I'm trying to estimate IOPS requirements of my application running on 32-bit CentOS 6.2. I started to take some measurement on a machine with SATA disks and I'm quite confused of difference between ...
I am relatively new to AWS and disk performance. I am trying to figure out how much provisioned IOPS does my application need to perform well. Currently My PHP and MySQL application is hosted on EC2 ...
IOPS write increased, Disk write latency decreased, Avg req size decreased - Page load speed decreased
I have noticed decrease in server performance (page load speed become lower), then I went to investigate and have found in munin graphs (which tracks server's resources) that there was big changes on ...
