Hello all. i would like to see what sort of speeds do you get generally get on a system running jbase. more specifically, we have a power 5 570 machine that runs AIX 5.3 TL 11 SP4 and we are running jbase 4.1.5.29 on top of that. the machine 8 CPUs at 1900Mhz and 16GB of memory. thats our production environment and its attached on a IBM DS4800 storage. our jbase and production environment are on the same filesystem that resides on 4 physical disks of the storage which are on RAID 10. a dd if=/dev/zero of=testfile0 bs=4096 count=1000000 gives me speeds of around and more than 110MB/sec. now running from jsh several SELECT statements or COUNT etc and looking through the topas utility but also nmon, the average read disk speeds will never go beyond 7-8MB/sec. rarely i will notice bursts of 20MB/sec but usually it runs around 5MB/sec or even less.I understand that theres also logical processing that needs to be done from the CPU so its not only disks, but still i feel that 7-8MB/sec is too slow since the system is capable of a lot more.running nmon to collect date throughout the duration of a COB i get average read speed of about 1 MB/sec and a max of 74MB/sec. that 74MB/sec sounds very good but its probably at a burst time period and lasted for less than a blink of they eye. Write speeds arent any much different either.all the speeds i mentioned are noticed while im the only user logged on the server. it would be nice to know what sort of speeds you are running on and if im the only one running so slow. Thanks.
