Slow performance sine updating to v8.6

[Marshall_IT]

Hi,

 

Since updating to v8.6 it takes longer to load a page, and loading the myFiles section takes the longest. 30secs to change to the myfiles page and upto 60-90 seconds to load the files section.

 

I've not changed anything else.

 

Is anyone else seeing this too?

 

thanks.

No answers for you.. but can you check the server CPU utilisation while you login (and at idle)? I've been seeing some slowness and im interested if it's the same thing or not..

(P.S. after you've checked CPU Util, restart the IIS service and see if it improves at all)

I think it's down to the recursive membership look ups HAP+ now uses. I'll be implementing some caching on this to improve the speed in the next release

Ok, can someone try this dll, it has some caching enabled for the role provider so it doesn't need to look up the user's roles each and every time, @mattgrimley this may fix the CPU spike as well

I've popped it on the live server - nothing untoward so far. Tried a login and it certainly didnt sit at 100% for any time. I'll reboot the server in a bit to give a clean test

 

Thanks @nickbro - that was quick work!

I was noticing some performance issues with v8.6, and since you said about LASSS it had to be the new role provider, so I added some caching to it. It only caches for 5 minutes (sliding scale) but that means that for 1 session the roles are cached. If you add roles to a user you will need to cycle the app pool to ensure the roles are correctly refreshed, I may add a button to the setup page to clear the role cache at some point in the future

Don't know if this is related, but it hasn't happened before today:

This morning, the portal Login.aspx is giving an error:

A restart of the IIS service cleared it. If it occurs again, i'll do some event log / firebug debugging

Odd, that's to do with the ip ban system, an app pool recycle should sort that, looks like one of the caching object had been deleted

Hi Nick, that has certain fixed the issue i was having, i'll let you know if anything else crops up, but look god for now.

 

Thanks ALOT!
