How to quickly store/read a large set of objects in a web application?

Question

Angular

We develop an application on Angular v4. We are looking for a local data storage acceptable in terms of performance for the application cache (with the ability to save). We considered such options as ForerunnerDB, lowdb, FileSaver.js. Not satisfied for one reason or another - performance or other limitations. The volume of saved data is approximately 60,000 objects, the desired time for saving such a data set is 10-15 seconds, no more. The storage must also allow multiple collections of objects to be written to. Maybe someone solved a similar problem in the project and the solution has such a performance? Thank you.
