Hi all,
I have a few more general questions to ask, if i may =)

My Sun Ultra 60 currently has 512Mb RAM. I'm familiar with x86 architecture, and know that 512Mb can be enough, but i'm still not that familiar with the Sparc arc and Sun machines (yet). Is 512Mb enough for that system, which has dual 340Mhz processors? Would adding more RAM show a noticable difference?

The applications i install from pkg-get, are they compiled or do they take advantage of both
A) The dual processors, and dual processing / multi-threading
B) The 64bit architecture ?
Is there any real way to find out? eg. apache2, mysql4, OOo.2, etc..

If i run Solaris 10 x86 on my laptop, do the ATI drivers support Solaris 10 ? If not, are there alternative drivers that may give 3D acceleration ?

Thanks.

RAM usage is not going to be substantially different from what you are used to experience on other architectures.
Adding memory always shows a huge difference when RAM is otherwise exhausted.
This is not a compilation flag, but most applications will take advantage one way or another of the dual CPU. But don't expect miracles, two 340 Mhz CPUs are beaten by Ghz+ recent CPUs.
Blastwaves applications target sparcv8 architecture (32 bits). That doesn't make a big difference on a system with 512 MB anyway.
"prtstat" will show you the number of threads an application is using, and "file" if an application or a library was compiled for 64 bit.
Both Xsun and Xorg are providing ATI drivers, not sure if any of them provide 3D acceleration though.
