Today, i upgraded this blog to Wordpress 2.8. The upgradation went fine without any problems.

Wordpress 2.8
But after upgrading, I felt that the Dashboard and wordpress admin pages were loading very slow. Each page was taking 5-10 seconds to load.
I then opened the blog and tried browsing some posts. There was the same effect. The blog was slow.
It was for sure that Blog slowed down due to Wordpress 2.8 Upgrade. My first suspect was to check the plugins. There are 40+ plugins that i use. I was sure that this is due to some plugin which may not be supporting Wordpress 2.8.
I went to Plugin page and disabled all plugins at one go and saw the pages started loading faster.
I then started enabling plugins one by one and then I found the culprit plugin that slowed down the blog post upgrading to Wordpress 2.8
.
The plugin was Performancing Ads plugin. I disabled the plugin, jumped to Performancing Ads and got the javascript code to display 125X125 Ad on the sidebar.
I was surprised and was also upset on myself to see that i was using a plugin instead of placing just a one liner javascript to display the ad
The problem was solved.
Did you guys find any problem? If yes do leave a comment about the problem and the plugin that caused the problem after upgrading to Wordpress 2.8. I am sure that this will be of help to all those who have faced problems after upgrading to Wordpress 2.8
