javascript - Store files in mongodb with Nodejs -


i saving files on fs of server , want save them in mongodb.(for easier backup , stuff).i want store files 4-5mb maximum , tried save them mongoose buffer type.i saved them , retrieved them noticed significant slow performance when save , retrieve files 4 or 5mb.

my schema:

let fileschema = new schema({ name: {type: string, required: true}, _announcement: {type: schema.types.objectid, ref: 'announcements'}, data: buffer, contenttype: string });

how retrieve them expressjs server:

 let name = encodeuricomponent(file.name);  res.writehead(200, {      'content-type': file.contenttype,      'content-disposition': 'attachment;filename*=utf-8\'\'' + name  });  res.write(new buffer(file.data));

my question should use zlib compress functions 'deflate' compress buffer before saving them in mongodb , uncompress binary before sending them client? make whole proccess faster?am missing something?
