My suspicion comes from the fact, that when using the application (web based) it takes some time to display data, when entering the application, after login in, so its slow.

Are you looking for a way to drive IO operations on the applicable LUN(s) outside of using dd like this?

Code:
dd if=... of=/dev/null

Even if you do

Code:
dd if=/dev/rdsk/c6.... of=/dev/null bs=64k

that won't give you an accurate picture of random IO operations because dd reads sequentially, thus giving an inflated view of the number of IO ops the LUN can support.

NAME
install-solaris - install the Solaris operating system SYNOPSIS
install-solaris install-solaris invokes the Solaris Install program. Depending on graphical capability and available memory at the time of invocation, install-solaris invokes either a text-based installer or a graphical installer. The following minimum requirements for physical memory dictate which features are available during installation: For SPARC machines: 128 MB Minimum physical memory for all installation types 128 MB Minimum physical memory required for windowing system 384 MB Minimum physical memory required for graphical-based installation For x86 machines: 256 MB Minimum physical memory for all installation types 256 MB Minimum physical memory required for windowing system 512 MB Minimum physical memory required for graphical-based installation In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number of fea- tures available. install-solaris exists only on the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the for more details. install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the installation media. Refer to the for disk space requirements. Refer to the for more information on the various menus and selections. See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcdrom (Solaris instal- | | |lation media) | +-----------------------------+-----------------------------+ |Interface Stability |Evolving | +-----------------------------+-----------------------------+ pkginfo(1), install(1M), pkgadd(1M), attributes(5) It is advisable to exit install-solaris by means of the exit options in the install-solaris menus. 23 Sep 2005 install-solaris(1M)
