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% |
| Build a large multi-project solution (using background compilation) | 222925.50 | 19861.88 | 11.22 | 8.91% |
| 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% |
| Load a large solution (first time) (Note: This is the improvement on XP. Vista has seen about twice as much improvement for the Load Solution scenario than XP. ) |
19946.25 | 18222 | 1.09 | 91.36% |
