A while back we debugged such mysterious issues in a larger scale install, and found a surprising reason: swap space. To get the maximum out of the memory on Solaris, you need to have at least as much swap configured as you have RAM. If you don't meet this, then Solaris starts to page out stuff even if there is plenty of RAM left. If you have e.g. a ZFS root install, this gets simpler, as the ZFS swap normally has a high upper limit. The defaults for UFS are pretty low though. > > -bash-3.00# prtdiag You probably meant prtconf if you wondered about the installed RAM. > prtdiag: failed to open SMBIOS: System does not export an SMBIOS table > > I am just about to retry it on a X2200 (4 cores, 8 GB), but I remember > that I have already seen this performance difficulties on this machine > too. More RAM solves part of the issue - you can use just approx. half of it if you don't take the above into account. Sorry about the late reply, but better late than never.
