The SIPAC (Integrated System of Patrimony, Management and Contracts) is a large-scale Java web system accessed by thousands of people on the management field of several institutions over the country. The system run through low-performance issues in some of its features, many of them accessed constantly. Many of these issues are only detected by the users themselves, on the fly. This paper presents an performance evaluation study of the features on SIPAC system, where the 10 features with the worst response times were found from the execution logs, which store the execution times of the features on the production environment. Later it was performed an execution trace analysis of the features on a test controlled environment by code instrumentation of the methods involved on the features, where it was figured out which ones are responsible for the low-performance on every feature. Then a code analysis of the methods was performed in order of find out what issues are present in such methods. Lastly a classification of the found problems was made and refactoring suggestions for solving the issues were given. In the end the paper presents all the results of those analysis as well as conclusions drawn from the spotted issues and refactoring suggestions.
