Limiting upload speed on Java?

由 三世轮回 提交于 2019-12-12 07:14:26
问题 I'd like to programmatically limit an upload or download operation in Java. I would assume that all I'd need to do was do check how fast the upload is going and insert Thread.sleep() accordingly like so: while (file.hasMoreLines()) { String line = file.readLine(); for (int i = 0; i < line.length(); i+=128) { outputStream.writeBytes(line.substr(i, i+128).getBytes()); if (isHittingLimit()) Thread.sleep(500); } } Will the above code work? If not, is there a better way to do this? Is there a

How can I add a download speed limit to this php script?

问题 I found this great script to download and protect the files from a directory: http://www.gowondesigns.com/?page.getfile And I saw this code from a website too: // local file that should be send to the client $local_file = 'test-file.zip'; // filename that the user gets as default $download_file = 'your-download-name.zip'; // set the download rate limit (=> 20,5 kb/s) $download_rate = 20.5; if(file_exists($local_file) && is_file($local_file)) { // send headers header('Cache-control: private');

NSURLSession bandwidth limiting

由 断了今生、忘了曾经 提交于 2019-12-11 02:15:50
问题 Is there a way to limit the bandwidth in NSURLSession ? I'm making file-sync-client for macOS like Dropbox/GoogleDrive/pCloud and they all have bandwidth limiting options, but I'm not sure how to configure NSURLSession to respect bandwidth limiting. 回答1: Unless Apple has added something very recently, NSURLSession provides no facilities for bandwidth limiting. The only ways I'm aware of to do that are: Use lower-level APIs that allow you to provide your own sockets and then throttle the data

Using trickle with Git

由 此生再无相见时 提交于 2019-12-10 04:26:56
问题 I would like to throttle a simple git pull using trickle. This seems like it should be easy: trickle -d 100 git pull , but when git shows its bandwidth rate, it still hovers around 3.3 MiB/s for me, much greater than the supposed maximum of 1000 KB/s. I am discouraged by the fact that it looks like trickle hasn't been updated in 8 years, but I am hoping I can still resolve this problem. Other random info that may prove helpful: Fedora 20 trickle -V : trickle: version 1.07 git --version : git

JMS message size

由 被刻印的时光 ゝ 提交于 2019-12-08 17:18:45
问题 I'm currently working on bandwidth limiting feature (don't ask me why, its not my decision) for application which use JMS (Spring framework JMS and Active MQ namely) to sending messages with payload between server and clients. I found lot of throttling methods to limit incoming JMS messages (but none of them based on actual bandwidth load), however I didn't find any possible way to limit outgoing message flow. So I decided to write Leaky bucket algorithm on my own. Is there some way how to

Limiting number of HTTP requests per second on Python

由 南笙酒味 提交于 2019-12-05 03:08:37
问题 I've written a script that fetches URLs from a file and sends HTTP requests to all the URLs concurrently. I now want to limit the number of HTTP requests per second and the bandwidth per interface ( eth0 , eth1 , etc.) in a session. Is there any way to achieve this on Python? 回答1: You could use Semaphore object which is part of the standard Python lib: python doc Or if you want to work with threads directly, you could use wait([timeout]). There is no library bundled with Python which can work

Best practices of high-performance network applications

问题 While testing out a UDP multicast server that I've written on Windows 7 Ultimate x64, I came across a most curious thing. Playing music with foobar2000 in the background significantly improved the server's transmission rate yet also incurred minor packet loss. Turning the music off immediately dropped the transmission rate to below acceptable levels but also produced 0 packet loss. (I have a client application which talks to the server and reports back unacknowledged packets) I am aware of

Limiting bandwidth of http get

I'm a beginner to golang. Is there any way to limit golang's http.Get() bandwidth usage? I found this: http://godoc.org/code.google.com/p/mxk/go1/flowcontrol , but I'm not sure how to piece the two together. How would I get access to the http Reader? There is an updated version of the package on github You use it by wrapping an io.Reader Here is a complete example which will show the homepage of Google veeeery sloooowly. This wrapping an interface to make new functionality is very good Go style, and you'll see a lot of it in your journey into Go. package main import ( "io" "log" "net/http" "os

Network throttling with chrome and selenium

Google Chrome 38 introduced the new "Device Mode & Mobile Emulation" functionality in devtools. In addition to choosing a device for emulation, it is also possible to emulate different network conditions : Optimizing your site's performance under varying network conditions is a key aspect of developing for a mobile audience. Device mode's network conditioning allows you to test your site on a variety of network connections, including Edge, 3G, and even offline. Select a connection from the preset dropdown to apply network throttling and latency manipulation. For example, we can set it to be
