Case Study: MS Learning & Consulting reclaims over 50% of development time with ZeroTurnaround's JRebel

MS Learning and Consulting - Customer Case Study

MS Learning & Consulting, led by founder Muhammed Shakir, is a 17‑year‑old consulting and training firm that runs a Liferay‑based education portal on Tomcat. Development was slowed by frequent redeploys: a 20‑second build plus 90–120‑second redeploy, performed about 15 times an hour by the solo developer, cost roughly 30–35 minutes of turnaround per hour and risked classloader leaks and PermGen OOMEs when Java classes changed.

The team adopted JRebel, which redefines changed classes in place instead of reloading the web context, avoiding new WebAppClassLoader instances and costly redeploys. Installation took minutes and immediately returned the wasted 30–35 minutes per hour to development time—more than a 50% productivity gain—while the developer continues to roll JRebel out to the web services layer and explore JRebel Remoting for lightweight test deployments.
