Analysis of the memory consumption and efficiency of the UI module WebVision in the busy environments

The module UI.WebVision was observed in extra memory consumption on a real big task working on Debian 9.

There were performed several actions of measuring about this module work on different Debian versions: 7, 8, 9, 10; where we have seen the clear degradation of effectivity of the memory allocation on Debian versions from 8.

Contacting the Debian community we revealed this problem as a disadvantage of GLibC in implementing memory arenas, which can be highly fragmentated in program environments what actively recreating the threads, due to linking the arenas to threads.

So, to fix this behaviour, we need to set the environment variable MALLOC_ARENA_MAX=1, what was be done for all live disks of the automation Linux distributive.

In general, the built-in library currently contains the following functions of the user calculation:

API of the unified implementation of the DAQ-templates

API of the unified implementation of the DAQ-templates has been implemented, applied and substantially tested.

Currently, this API is applied on the primary modules of the subsystem "Data acquisition", that is LogicLev, ModBus, Siemens, and as an optional feature for the controller object of the JavaLikeCalc module. From modules of other subsystems to the templates support, the protocol modules UserProtocol, ModBus and the graphical interface module WebUser have been adapted. Moreover, the use of templates in the modules UserProtocol and WebUser conceptually improved their functions and expanded the ability to create complex templates.[more]
