Hi Piyush,
I don't believe we ever received a sample related to this. If you can make one, please do and send it to our support address. Reference this post and rename the .zip file extension so it doesn't get spam blocked.
Per our previous post, we haven't seen a slowdown. If you see a scenario where the first time it's taking longer than later, it could just be that the .NET assemblies are loading up the first time since they all JIT (just in time) load. Still, 1.2 seconds to update the title seems way too high. When we tested ApplicationName updates, they went through instantly.
