![]() A buffer larger than this may help speed I/O, but often by only a few percent, say 5 to 10%. Buffering is a basic and important technique for speeding I/O, and several Java classes support buffering ( BufferedInputStream for bytes, BufferedReader for characters).Īn obvious question is: Will making the buffer bigger make I/O go faster? Java buffers typically are by default 1024 or 2048 bytes long. BufferingĪpproaches 2 and 3 use the technique of buffering, where large chunks of a file are read from disk, and then accessed a byte or character at a time. But it's useful to keep in mind where the time goes, and how it can be reclaimed when necessary.Īpproach 2 is probably "right" for most applications. It may also be less readable than the alternatives. Such an approach may be error-prone, especially in handling end-of-file events, if it is not carefully implemented. This huge speedup doesn't necessarily prove that you should always emulate the third approach, in which you do your own buffering. Or about a 17 to 1 difference between the slowest and fastest. This distinction is important in some contexts, as several of the examples will illustrate. Because of this, some translation is required to read characters from a file. In the Java language a character is represented using two bytes, not one byte as in other common languages such as C. One is based on streams of bytes, the other on character sequences. When discussing Java I/O, it's worth noting that the Java programming language assumes two distinct types of disk file organization. Note, however, the discussion does not cover application design issues, such as choice of search algorithms and data structures, nor does it discuss system-level issues such as file caching. For example, to read yourtextfile.txt at 400 WPM, you would enter: cat yourtextfile.txt. Quickly open TXT document in a browser without. To install it, clone the GitHub repository on your device and type in the appropriate command to read a document at your preferred word-per-minute (WPM) rate. Our TXT Viewer tool is easy to use and 100 free. Use SwiftRead to breeze through any text in a fraction of the time. Use it to view TXT files on your mobile phone, tablet or laptop from anywhere. The first set of techniques presented below cover low-level I/O issues, and then higher-level issues such as compression, formatting, and serialization are discussed. This TXT Document Viewer provides professional quality rendering, fast thumbnail navigation and text search. Most of the techniques center around tuning disk file I/O, but some are applicable to network I/O and window output as well.
