Effect of batch size during testing time?

[Theerit]

Hi, during my run time I have found that batch size parameter could impact the performance of the model during testing time?, Could it be due to fact that the same input sentence with different size of padding ([0,0,1,1] in batch size of 1 and [0,0,1,1,1,1,1] when mixing with other examples) can lead to some difference in output from final layer of the model?
