For my dnn site (4.3.5), now i need about 15-20 seconds to load the startup page.

I know that keep on pinging the site may improve the performance. However, since the server is not hosted by me and i cannot perform such strategy.

I am wondering what else i can do to keep the site live and running. Or other methods to do it?

any suggestions?

Thank you

Thank you.

But i would like to know if there are alternative ways that no need to rely on third party?

Meanwhile, i read an article that version 4.4 has improved this problem, isn't it?

Thank you.

DNN 4.4.1 is a lot faster once it is up and running, but it is not noticeably faster on the intial startup of the site has cycled down.

You might try the free PageBlaster module.  It makes startup a little faster because your pages are cached on disk, so they don't need to be rebuilt on initial startup.

Running a keep-alive service is the only way you will keep it from having that initial startup lag though.

If you don't want to use a keep alive, then just make sure you have enough traffic that your site is nver idle for more than 20 minutes.
