I will rerun my tests on 3.5 when I get some time later this week. Yes true I missed that. I will rerun my tests on 3.5 when I get some time later this week.

The first set of 20 tests, initializes SortedDictionary and then initializes Dictionary. The next set of 20 tests, initializes Dictionary and then SortedDictionary. Actually in my case, the large memory allocations are done each time they are run (because i instantiate new instances of each object) Hi Vald,

Perhaps i was not clear in my posting, i’ve actually did 2 sets of testing.

The first set of 20 tests, initializes SortedDictionary and then initializes Dictionary.
The next set of 20 tests, initializes Dictionary and then SortedDictionary.

Actually in my case, the large memory allocations are done each time they are run (because i instantiate new instances of each object)

You always process SortedDictionary before Dictionary. If you read the description of my tests I have tried those in different order and what is more important each was performed separately. When you start performing operations on the SortedDictionary you initiate actions of the virtual machine related to large memory allocation and then when you reach the Dictionary the hard work is already done. I would encourage trying the same experiment in different order. But it is true that my test was with .NET 2.0 so it may have changed in 3.5. There might be one problem with your test.
