Memory leaks are found often in our C++ application which is running
on Solaris machine. So, it was decided to link with libgc.so which
comes with Solaris.

Before start doing that, I would want to know your
experiences/thoughts/suggestions on using this library.
- Will this really fix all memory leaks in a C/C++ application?
What are the leaks that can still escape from this?
- Will it cause any performance impacts ie. reducing the existing
performance
in a time critical application?
- Any other things that we have to take care?

Kindly pour in your suggestions.

I'd say you should try rather hard with some memory leak finding
tool, and plug those rather.

Often. Not guaranteed though.

Leaks that arn't true leaks. e.g. still keeping a pointer
to something you really should have disposed long ago.

malloc and especially free can take substancial longer time now.

There is another good tool purify that comes with solaris box.
This  finds memory leaks - memory that  has been  allocated but can no
longer be acessed
because  there are no pointers to it.
This also detects
reading / writing beyond array limit
reading / writing freed memory

Refer man purify

Purify is good, but isn't included with Solaris.  You have to buy it
from IBM (formerly Rational, before that PureAtria, and long ago, Pure
Software).   http://www-306.ibm.com/software/awdtools/purifyplus/

Sun does have very similar functionality in the dbx debugger included
with the Sun Studio compiler products.
