![]() ![]() So first, let’s explore the Smallworld 4 GIS architecture to understand how it works. That’s akin to the differences between Smallworld 4 and 5, “under the hood.” Sure, they’re both cars you drive in similar ways, but under the hood, the propulsion mechanisms are worlds apart. ![]() Think about the difference between a Volkswagen Jetta TDI diesel and a Tesla Model 3. While version 5 is mostly backwards compatible with version 4 at the Magik level, the core technology beneath is different. With that preamble out of the way, let’s take a look at what’s going on under the covers in order to identify and work around issues that may affect performance. ![]() However there are quite a few benefits because the JVM has been around for a long time, is stable, optimized, secure, runs in myriad environments, receives consistent updates and can execute code quickly once its initial bootstrap is complete. Starting a new instance of a JVM as well as loading and verifying bytecodes, not to mention other overhead tasks that weren’t necessary in Smallworld 4 (SW4), plus executing extra code introduced by SW5-specific implementation details, simply takes time.Īnd that in a nutshell is why SW5 generally takes longer to start than SW4. Smallworld 5 requires more resources (such as CPU and memory) because it runs on the Java Virtual Machine (JVM) and, quite frankly, the JVM is a resource hog.
