----------------------------------------------------
Hi all,
I'd like to know if there are any documentation with detailed requirement at OS level to install and run Sybase ASE.
Why this question?
Today I have a dataserver installed on a Solaris zone and my feeling is the 'dataserver' is slow.
I don't know whether it's a misconfiguration at dataserver level or OS level.
What makes me think this way?
today I took a backup of a 361Gb db and the operation took almost two hours. This seems a bit long to me
Now I'm running a drop database and the operation looks a bit long to me.
As my 'drop database' command is running, I'm also execution some iostat command to see if the bottleneck is at IO level.
This is a sample of results I have

It looks to me there's IO bottleneck on ssd25 but I'm wondering if IO settings is optimum?
Thanks for any feedback
