I used partitioning on low end phones to increase ram and app2sd or link2sd, but as a temporary fix. It's a risky data loss procedure on some phones, as partitioning wipes data. Some phones allowed app2sd without partitioning. Your phone does not support it. So don't go ahead.
To get free space, delete unnecessary preinstalled apps using app master.
Note: Sd card is slower by the way, unless you have a Class 10 or high speed SD card. In past, I transferred apps (created a link) on Sd card and they caused some lagging.
