- use fixed-sized storage;
- use DiskSize property to prepare the storage for writing of the large file. Reserve the space of file size + 10% (approximately).
When you add files to the storage, you can experience significant slowdown. This happens when you add the large file to the newly created resizeable storage. The cause of the slowdown is that SolFS adds new pages as you write the data. When the new pages are added, the storage itself is expanded (this takes time) and also certain other file system management operations are performed. The smaller the page size is, the more significant slow-down is.
