The goal is to deliver files with a nodejs http server.
The *problem* is the *transmission* from the server response to the
*browser*.
I deliver a string as content as shown in program code.
VPS: debian 7 / SSD / 2 core / ~30ms ping
Some string size benchmarking (**content-download time**)
- 1 kb: 0,18 ms
- 10 kb: 7,00 ms
- 20 kb: 47,50 ms
- 30 kb: 55,00 ms
- 40 kb: 58,10 ms
- 50 kb: 86,20 ms
- 60 kb: 93,10 ms
- 80 kb: 107,10 ms
- 100 kb: 120,00 ms (nginx needs 0.31ms)
>From start to finish the response in the server. it takes ~1ms no matter
what file size, so the problem is between nodejs sending the files and the
browser receiving the files.
*Program code:*
// var request => the http incoming request
request.socket.setNoDelay();
request.connection.setNoDelay();
// var response => the response from the http incoming request
response.on('close', function () {
console.log("[ABORTED][%s] %s", request.connection.remoteAddress,
request.url);});
response.on('finish', function () {
console.log("[SUCCESS][%s] %s", request.connection.remoteAddress,
request.url);});
// get the content of the file (takes ~0ms)var fileContent =
fileSystem.readFileSync(filePath, 'utf8');
// Configure response header
response.writeHead(200, {
'content-length': ''+fileContent.length,
'content-type': 'text/plain',});
// Send content
response.end(fileContent, 'utf8', function(){
console.log("Ending response took %sms", Date.now()-timeB2);});
