Sadly Solaris seems to have the same problem. I
have a Sun Ultra-60
which once seemed like a nice box. Sadly it no longer is. It takes
around 30 minutes to build the Hercules emulator.
The current Windows/7 box will build Hercules mainframe emulator (32 and
64-bit binaries) in under a minute. Whilst I like the U-60 I think its
un-usable....
Comparing current machines with fifteen-year-old machines is far
from
fair, but...What's the config of the U60? If you've got dual 450s and
2GB, which is the most it can support, it should be doing just fine.
Another issue there may be GCC, which is hopelessly fat...using the Sun
compiler, things will compile much faster, and it generates
significantly faster binaries on top of that.
I think it only has 600 MB of RAM,
but its a dual 450 with a 15k disk
from an IBM server and of course Hercules won't
compile with Sun Studio..
.. I keep it because its sometimes more nostalgic nice to
have a slow
mainframe. To be fair the PC I use is a 4-core 23Ghz i5 with 12 gb of
RAM so its pretty slick.
Solaris does much, much better on machines with
lots of processors.
Two (or four, eight...) is not a "lot" of processors...think 16+. Each
instance of each device driver runs in its own thread, so I/O is very
smoothly interleaved. They can get an amazing amount of work done if
one knows what one is doing. That's the kind of system current Solaris
is optimal for.
Ah yes I kind of understood that....
