Poor query performance with: set statistics time on (SQL2K5)

Hi,
I try this query:
--
use AdventureWorks
go
select c.*,o.* from sales.salesorderheader o join sales.customer c
on o.customerid=c.customerid
go
set statistics time on
go
-- try the query again
select c.*,o.* from sales.salesorderheader o join sales.customer c
on o.customerid=c.customerid
--
the second query after setting "statistics time" is very slow on my
computer. I'd like to know if anybody else has the same problem?
Thanks in advance,
LeilaI tested it on 2005 SP1 using Management Studio. I ran it as give,
and with the order reversed. I also added select getdate() lines to
give a measure of elapsed time. Results were returned to a grid.
With statistics time on the query took a bit more than twice as long
to run.

I can also reproduce this behavior. I don't have an answer
or workaround, but I'd suggest one of you file it as a bug

Yikes.
Just for the record, I've been using statistics io on a lot over the
last year or so, and on SQL2000 it generally had a small impact, maybe
5 to 10 percent.
