I think comment forms should not accept a double submit of the same thing within 10 seconds. Also, I suspect some of the delay in handwritten stuff is important processing like antispam checks. CPU and network efficiency are wonderful things. But if a lightweight solution can't provide the same level of features and convenience as a modern package, I would toss it without a second thought. My original personal site was handmade HTML with a PHP header. I eventually got rid of it for DokuWiki and never looked back. If it was a pro site, I think I would just use WordPress. It is an impressively high performance site you have though!
