batching

I have an array that contains an array of promises, and each inner array could have either 4k, 2k or 500 promises. In total there are around 60k promises and I may test it with other values as well. Now I need to execute the Promise.all(BigArray[0]) . Once the first inner array is done, I need to execute the next Promise.all(BigArray[1]) and so on and so on. If I try to execute a Promise.all(BigArray) it's throwing: fatal error call_and_retry_2 allocation failed - process out of memory I need to execute it each of promises in series, not in parallel which I think that’s what Node its doing. I

I'm currently working with upgrading and restructuring an OpenGL render engine. The engine is used for visualising large scenes of architectural data (buildings with interior), and the amount of objects can become rather large. As is the case with any building, there is a lot of occluded objects within walls, and you naturally only see the objects that are in the same room as you, or the exterior if you are on the outside. This leaves a large number of objects that should be occluded through occlusion culling and frustum culling. At the same time there is a lot of repetative geometry that can

I am trying to develop a game where I am rendering up to 300 cubes on screen. The performance of modelBatch when creating new modelInstance for each cube is terrible. There is no 3d batch that batches all the cubes to one draw call as far as I know. So I am desperately trying to batch them somehow. This question is directly related to this one: LibGDX 3D increase perfomance The answer posted batches all the cubes successfully but when environment is added to get some lighting it appears that the cubes have missing sides or something else is wrong with them. Heres a picture: Here is my cube

I want to select one of the above orm. What is the difference between nhibernate and entity framework in batching? NHibernate can: Send multiple updates/inserts/deletes at once Load multiple proxies of a type at once Load multiple collections of a type at once Execute object oriented DML statements Manually group queries in a single roundtrip (multiqueries, futures) EF can: None of the above Ladislav Mrnka The difference is that EF natively doesn't have any command batching so every update, insert or delete is executed in separate round trip to the database - but in my previous question are
