Use BufferedStream: using (FileStream fs = File.Open(path FileMode.Open FileAccess.Read FileShare.ReadWrite)) { using (BufferedStream bs = new BufferedStream(fs)) { using (StreamReader sr = new StreamReader(bs)) { string line; while ((line = sr.ReadLine()) != null ) { } } } } http://cc.davelozinski.com/c-sharp/fastest-way-to-read-text-files
