 I have 2 portals in my dnn installation... both of them are aggravatingly slow... and one page in one of the Portals just gives me an error page and never loads at all.  Prior to this afternoon, it would load albeit slowly, but now I only get an error page.

I've tried rebooting the application, which kicks the page back on, and it loads super-quick.  But only for like 30 seconds - it immediately goes back to delivering nothing but an error page.

Can anyone direct me to some best practices or a list of things to check or... anything at all that will help me at least get the page to deliver content... 

The site is running on a dedicated web server, which has hosted our corporate sites for years w/o incindent, so I don't think the hardware or hosting company is an issue.  Anything else?  Thanks a ton...........

If you google "dotnetnuke performance" you should get a lot of info, also check out Mitchel Sellers site in the results.

 thanks for the suggestion... I've implemented some of the ideas I found at Mitch's site - this seemed to help last night, but as of this morning, it's broken... again...

 

I posted on their forum as well, but perhaps someone here has another suggestion?  Here's what I posted.  Thanks again.

 

I have a page (it is a shop locator using google maps and an off site database) that worked until yesterday afternoon albeit always very very slowly.  Now, if I try to access the page, it just spins and spins and eventually spits back a generic "turn customErrors Off" message. (even tho customErrors ARE off in my web.config file...)

 

If I go to Host Settings and Restart Application, the page will load super-quick for a short period of time (across multiple browsers on different machines), but then it will start to fail again.

 

Last night, I was reading an article on this site and changed the (Host) Performance Settings to the suggestions found here (Heavy Caching and Module Caching = Memory), restarted the application, and everything looked good for maybe an hour or so until I finally passed out from frustration with dnn.

 

Got up this morning, and the page was still refreshing but, by the time I got to work, it was broken again.

I am now able to restart application and have the page stay active for maybe 5 minutes (vs maybe 1 minute yesterday), but obviously that's completely unacceptable.  Sometimes I will now get a "[HttpException (0x80004005): Request timed out.]" message instead of the generic message, but the result is the same... FAIL.

 

Thanks...

What version of DNN are you running? My guess is that the Scheduler is causing your problems...

In the database or Host-> SQL tab, run this query, "Select count(*) from ScheduleHistory". If you have greater than 500 rows, that is most like the culprit. If that's the case Google: DotNetNuke ScheduleHistory.
