add millisecond option to keepalive timeout on apache configuration page
Open Discussion
On the apache configuration page, there should be an option to specify the keep alive time in milliseconds because apache 2.4 and later honors this.
Hi Mike,
Have you ran into situations that demand milliseconds? If so, could you share a couple of those situations with us?

According to various documentation including apache's own docs, a high keep-alive timeout can hurt performance because the longer the timeout, the lower the resources available for newer users because one running apache process is handling the timeout and if all running apache processes are used up then the next set of people who want to access the website will have to wait until one process is free. the time to wait may be the keepalive time plus the tcp closing time (TCP WAIT STATE or FIN timeout), especially if a million people wanted to access the server on the same split second. The reason why I suggest adding a ms option is to enable remote users with slow connections to still connect.
