Now my results are:

00:00:17.6532821: 3.14159265359043
00:00:28.0364287: 3.14159265358974
00:00:00.9239252: 3.14159265359043
00:00:05.8214685: 3.14159265358968
00:00:00.5391163: 3.14159265359011

so it's significantly better now,

I have added Your version of linq query, and it's run time is:
00:00:22.8898434: 3.14159265358974
net result:
00:00:01.2046403: 3.14159265358968

net's ParallelEnumerable implicitly forces range partitioning
