quick and dirty?
for win32 ... on the server console

in sqlplus ...
spool
set pga_workarea_policy manual
hike sort_area_size
hike dbfmbrc
take a statspack snapshot
fire up filemon.exe (from sysinternals), filter for the mount points of interest exec dbms_stats.gather_database_stats(cascade=>true ...); stop capture of filemon.exe, save the file take a statspack snapshot
dump a statspack report
upload the filemon.exe log into excel

works for me.
