recently I installed sas (9.1.3 sp4) on ubuntu and I felt that it is slower
in some cases.
for this reason I tried to install the same version via wine on linux and I
found that sas on wine is faster than the same one on linux itself. for
example the following sas code:
proc iml;
x=j(10000000,1,.);
call randgen(x,'normal');
y=x[:];
quit;
windows:
real 1:40
cpu 1:30
ubuntu:
2:05
1:72
even the I/O in wine is faster
for example creating data:
windows:
36.02
34.48
ubuntu:
47:60
47:38

A collegue used sas on windows to import and index a 6GB, 16m obs data
set on windows. The 12 minutes elapse (<3mins cpu) was a lot shorter
than the 40 minutes cpu time the same indexing took on a mainframe.
..... but the pc was servicing just one client, and not several
hundred.
Simple performance stats are sometimes not informative enough
