I know that some people were big fans of the ability to read comments on entries right on the front page at Wizbang, but I’ve removed that functionality for one main reason – speed. The number of comments per entry times 20 (the number of stories on the front page) made for a very large index.php file – one that had to load before readers could view it. Uncompressed the size of the front page dropped from nearly 1MB to 160K, meaning that the page should now load around 5-6 times faster. Leaving a comment has always involved loading the page for the story you’re commenting on, now reading comments will do the same.
That seems like a small price to pay for the performance increase. I’ve left the prominent text link to read or add comments, but you can also get there by clicking the comment icon or the entry permalink.
