I think the bigger parties tend to "hog" the xp. I keep all my DS LoA parties pretty small such as a max of 4 people and I think that spreads the xp better. Not everyone can have as big of a slice of cake, so to speak (mmm cake....)
Your difficulty settings also play a role in xp gain. Sometimes I just have one party member doing the work and the others strictly playing a support role by equipping them with healing hands spell. The DS Revived mod gives healing spells a bit more experience gain, so they don't lose out too much. That works for me because I like hybrid characters.

Try tinkering around and see what works for you.
