从vs2005升级到vs2008的理由

作者从性能的角度分析了2005和2008的区别，下面是性能表格：

Scenario	VB2005 Time (ms)	VB2008 Time (ms)	VB2008 is x times faster than VB2005 (2005 time/ 2008 time)	VB2008 takes x% as much time as VB2005 (100% * 2008 time/ 2005 time)
Build a large project (using background compilation)	222206.25	1352.88	164.25	0.61%
Build a large multi-project solution (explicit build operation)	1618604.75	57542.75	28.13	3.56%

Responsiveness after adding a member to a class	327.00	36.50	8.96	11.16%
Responsiveness after opening a project	255551.25	38769.38	6.59	15.17%
Invoke Intellisense to see a list of types (first time)	1192.50	530.5	2.25	44.49%
Edit-and-Continue in a solution with xml comments (first time)	441.25	210.5	2.10	47.71%
Responsiveness after changing a method statement	390.25	236.38	1.65	60.57%
10 Steps in the debugger (subsequent times)	1850.75	1167.13	1.59	63.06%
Invoke Intellisense to see a list of types (subsequent times)	79.25	51.5	1.54	64.98%
F5 when the solution is already built (subsequent times)	385.20	278.7	1.38	72.35%
Item gets added to the Error List after making an error	531.25	394.5	1.35	74.26%
10 Steps in the debugger (first time)	1336.50	1150	1.16	86.05%
Responsiveness while background compiling on an open solution	4803.00	4284.75	1.12	89.21%
Load a large solution (subsequent times)	13667.5	12407.25	1.10	90.78%
