Could be. If your sd card isn't at least a Class10 then I would highly recommend upgrading it. The sdcard needs to be able to keep up with the processing power of the phone or else you're just not taking advantage of the read/write speeds of modern devices.and what a huge difference it will make. If you do have a class10 or higher then backup everything then reformat it and see if that helps. Google instructions on how to format your card before you attempt it, unless you already know how to do it right.
Whichever is easiest for you; pull /system/app/SamsungIME.apk from the ROM zip, paste it to same directory on phone and set permissions to root, root rw,r,r (0,0, 0644) and reboot -or- just flash the ROM again.
