Since the Information Blocks module is deemed very “heavy” to create light references or store a large amount of data (when the module behavior is not very efficient) there appeared the need to create a substitute to infoblocks (Highloadblock module) that was much simpler and “lighter”. The new module is available from product version 14.0 and is written on the D7 new core. The data structure of this module makes it possible to use the module for loaded projects.
Note: Highloadblock and traditional infoblocks are different things. That is why there is no possibility to convert traditional infoblocks to Highloadblock. It is similar to the conversion of a forum in wiki. Technically, a similar structure can be created, and then data may be transferred. But it makes sense only for a specific project under certain circumstances.
