Performance does take a hit when using synchronization. I think the way to reduce this hit is to synchronize only a block of code that will be accessed by threads and not synchronize the entire method.

yes.the performance will be down if we use synchronization.
one can minimise the penalty by including garbage collection algorithm which reduces the cost of collecting large numbers of short- lived objects. and also by using Improved thread synchronization for invoking the synchronized methods.the invoking will be faster.

It is very useful because we can make only one thread to access the resources at a time with this we can avoid deadlock situation.
