performance gone down with AHC and time out errors

[Nitin Handa]

Hi,
I just now switched our default JDK's HttpURLConnecton based implementation with Grizzly based AHC but I see that performance of our app has gone down with AHC. I am also seeing below errors very frequently even though timeout is set to 60 second:

Another set of error that i see is:
