Unfortunately, it's very hard to give a good answer to this question as
stated. If the model is underfitted, giving it more iterations might
result in performance increase. If the model is not underfitted, giving
it more iterations may improve its training set performance while
worsening its ability to predict non-training samples.

Have you tried it yourself?
