There are a number of configuration parameters which should be tuned
for your particular server, which wi

We are making some performance measurements, we are trying to determine query
execution behavior. Lets say we have 4 tables T1, T2, T3 and T4
and the query has the form:
select * from T1, T2, T3, T4 where (T1.a = T2.b and T2.c = T3.d
T3.e = T4.f)
where a,b,c,d,e,f are properties of the re
