I am attaching the SVG file and also I think I found where is the problem is.
During the process of conversion, Batik is uncompressing the images and placing the raw data in PDF, that is the reason it is increasing the file size. Thank you very much for your kind help and ideas in this issue.

Without looking at the content I can't be sure but I suspect that you have serveral rasterized layers that are being stored in the PDF file. So taking the tiff file as a bench mark for the size of one layer, if you had 10 or so layers you would quickly reach the 2MB mark.
