Are you talking about the software or the number of posts?

As far as the software goes, vBulletin is full of features and options and it's PHP based. ZeroForum is always going to move faster. The owners deliberately designed the software to be trim and light, and to move faster at the tasks that irritated them when they were using other software.

The owners also make sure that there's seldom any overhead. Honda-Tech's owners protest every time you add an IP ban because it adds to the overhead.

At HAN, there are several IP bans in effect, together with other hacks and scripts that tend to slow the response but give the readers what they appear to be asking for.
