A comparative analysis of the Slony-I and PgPool-II data replication tools was carried out, to select the best alternative in the implementation of an integrated system of high availability for the management of academic tutoring in Higher Education Institutions, established as Study parameters the response time against the execution of SQL statements, the use of CPU, memory, and hard disk. An N-Layers web application was developed using PrimeFaces and PostgreSQL, integrated into an Academic System through SOAP web services. To carry out the tests, master and slave database servers were configured under a Linux environment. The performance tests were based on the Apache JMeter tool, simulating 282 requests per second in an instant of time, observing that PgPool-II consumed less resources with an average of 2.80%, however, Slony-I was more effective at carry out transactions with just 0.009% error.
