FileUploadHandler.chunk_size

Size, in bytes, of the “chunks” Django should store into memory and feed into the handler. That is, this attribute controls the size of chunks fed into FileUploadHandler.receive_data_chunk.

For maximum performance the chunk sizes should be divisible by 4 and should not exceed 2 GB (2³¹ bytes) in size. When there are multiple chunk sizes provided by multiple handlers, Django will use the smallest chunk size defined by any handler.

The default is 64*2¹⁰ bytes, or 64 KB.
