I really appreciated. I have a 256k line in my home that I use to run my web server. My server is a P233 with 96 MB RAM and 4.5GB IDE HD. OK, Everytime there is a request, Apache have to get the web page from the HD since I see the HD lights come up when I request a page. However, I need to know if apache can preload this pages into server RAM and then get them from there. My analogy is simple, RAM access is faster than HD access. Iam not taking about using the computer cache or swap file. I am taking RAM chips. I have been reading a little beat about MFS. Would this be the solution that I am looking for? Or, Does Apache have a directive that can preload web pages in RAM. Right now it takes a few seconds to get a webpage in my internal network from my webserver. My expectation is that the web page should be loaded in my client across the room in less than a second. I have a 10MB network at home with seven computer, 4 of them FBSD. Thanks for the hit pages tip using grep -Max To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
