Hi Amruta,
I have run a test with a SOAP and a REST interface on the same server, to retrieve the same resource (just a few Kb).
My results were pretty much as expected:
SOAP
REST
I must assume that there is something unusual about your setup which accounts for the large difference you're having, as REST and SOAP basically should have very similar performance (but of course, that can vary according to your server settings, caching, compression, encryption etc).
Please do some tests for that, for example by varying the size of the payload, and see how that affects your tests.
Good luck,
