Browser responds slowly post RIU upgrade

Al B. Fuct · #1 08-20-2008, 05:04 PM

Since the recent RIU forum sotftwe upgrade, my browser has been running horribly slowly when browsing RIU. It took several seconds to scroll from the top to the bottom of a page. I suspected a hung or looping Javascript, so I opened the Java console and dumped the thread stack.

This is the Java dump log. It looks like it was trying to load something it could not get.

Done.

After doing the thread dump, the browser response returned to normal.

Any clues, admin? Should I clear the browser cache, perhaps?

Thanky.

might be a good idea to clean out the cache, we upgraded the software because there was bugs in the old one.... Give it a go and let me know, once we are fully migrated i will pick it apart and see some problems i am sure

Go to Tools/Java Console. A box will pop up, hit 'v' and enter.

Everything runs fine for me, have you tried loading it in firefox?

Al B. Fuct · #7 08-20-2008, 10:12 PM

I only use Firefox. 3.0.1 installed at the moment.

I've dumped the browser cache and all seems OK now.
