Dưới đây là nội dung một bài viết mà tác giả tự so sánh giữa 2 site sử dụng DNN v4.9.5 và v5.4.4. Tất nhiên việc so sánh chưa thực sự là chính xác. Nhưng nó cũng là một nguồn tham khảo tốt.

This is just comparing the payload of the standard Terms page in 4.9.5 and 5.4.4. That means it shows only text and has one container. This is using my own skin, which uses the light-weight NorthSky Menu. One 22kb logo jpg and 10 tiny png files totaling about 2kb are also included. Both are running on my own quadcore server. I'm using Firebug and PageSpeed to get the results.

4.9.5
Score: 79 out of 100
23 resources
239Kb uncompressed
95kb compressed
Full refresh cross-country: 2 seconds per page load
On server desktop: 300ms

5.4.4
Score 74 out of 100
30 resources

148kb compressed
Full refresh cross-country: 3.5 seconds per page load
On server desktop: 520ms

Most of the increase is in additional script files, and it's quite a hit really.
