问AsParallel:对于容器中的少量元素有意义吗？

EN

public class ReplacementService : IReplacementService
{
    public List<int> GetTeamReplacementWeight(int iTeamId)
    {
        IEnumerable<TeamReplacementGroup> groups = TeamReplacementGroup.GetTeamGroups(iTeamId);
        List<int> weights= groups
            .Select(group => group.GetWeight())
            .AsParallel()
            .ToList();

        return weights;
    }
}
