First of all, the saints do not perform miracles. The miracles are performed by God at the request of the saint. Each individual case is based on its own merits.

Miracles were not required for declaring a person a saint in the early years of Chrisitianity. The person would have been declared a saint by popular acclamation to a bishop based on the lives and merits of the candidate. This was especially true if the person died the death of a martyr as it was felt that making this ultimate sacrifice for Our Lord would be an automatic designation of that person as a saint. Even today, miracles are not always a requirement for canonization, especially in the case of martyrs.
