A question about load balancing (network share method)

Hi,

I have 3 servers setup - 1 server acting as db server and network share, the other two as front end servers.

I've followed the documentation exactly except I'm curious about one part.

Which server should I access the backoffice through? I'm currently accessing it through one of the front end servers. In the documentation it says this is wrong but it's not clear for setting up over network share.

Also, I'm running 7.2.8 and the cpu is hitting 99% even when there's only a couple of users are on the site. What would cause this? I've read about KB3000850 but I've just installed the latest windows update to try fix it - or should I remove KB3000850 altogether?

As long as you always access Umbraco through the same server it's fine to be one of the front end servers.

Are you using server 2012R2? Have you installed KB3052480?

Thanks Jeavon. Yeh I'm running server 2012R2 with KB3052480 installed.

I even replicated the site and tested it on one of the front end servers but the CPU still peaks really high. Really at a loss with this one. Is there any tool I could use to debug this and find out why the cpu is going so high?

I should say as well, we installed all updates and upgraded to 4.6.1 on the server yesterday to see if that would help. It unfortunately didn't.

I would use NewRelic and execute a thread profiler while it's at 100% to find out what's going on

Thanks, I used dotTracer instead

Most of the processing is "Native or optimized code" ie IIS... so am I correct in thinking that IIS is the issue here?

Have you had a look at MiniProfiler also?

Thanks Jeavon,

I've ran the mini profiler and it looks like the app is taking it's time finding the partial views.

Tried googling but can't find anything...
