![]() ![]() You can follow these steps to perform a clean boot.Ģ) Type “ msconfig” into the Run box and click OK. In this case, you can perform a clean boot (boot your computer without third-party programs) to find out what services or programs are causing the issue. If the problem doesn’t occur in the Safe Mode, the problem can be caused by third-party services or programs. To troubleshoot, you can enter Safe Mode and see if your browsers are working slowly in Safe Mode. Software conflicts can cause the browsers to load pages slowly. Here’s how to reset TCP/IP:ģ) On your keyboard, press and hold Shift+Ctrl+Enter, then Command Prompt will open as administrator.Ĥ) At the Command Prompt, type the following command and then press the Enter key on your keyboard.ĥ) Restart your computer and check if your browsers are loading pages quickly. You can reset TCP/IP if you have internet connection issues like browser working slow issues. Usually, drivers can be downloaded from the Drivers, Support, or Download section. Then Windows will search for a new driver and install the driver automatically.Īlternatively, you can verify your graphics card’s model and download the latest version of the graphics card driver from the device manufacturer’s website. Right-click on your graphics card device and then select Update driver.ģ) Select Search automatically for drivers. To fix the problem, you can try updating the graphics card driver.ġ) Open (learn how to access Device Manager)Ģ) Expand category “Display adapters”. Method 2: Update the graphics card driverīrowser slow loading page issues can be caused by outdated graphics card drivers. If not, you can google well-known software like Malwarebytes. The benchmark numbers are thus download_http: download took 0 seconds, average speed: 211.05 MiB/sĭownload_ibrowse: download took 0 seconds, average speed: 223.15 MiB/sĭownload_hackney: download took 0 seconds, average speed: 295.83 MiB/sĭownload_tcp: download took 0 seconds, average speed: 595.If you have installed antivirus software or antimalware software on your computer, just launch the application to scan your computer to detect virus and malware. Once, I removed save action in download_loop_hackney(), hackney is the fastest defp download_loop_hackney(client, file) do Test needs to be run more than once (may be three times).Although saving to /dev/null, the file saving has a cost. Secondly, except for hackney, none of the other libraries stream the payload to file.Hence for testing, I changed to local resource You are using a remote resource which is effected by externalities making benchmark numbers. ![]() Going back to the benchmark, three clear issues, I am able ascertain Quantity = Float.round(bytes_per_second / :math.pow(1024, exponent), 2) "ĭefp bandwidth_to_human_readable(bytes, microseconds) doīytes_per_second = bytes / (microseconds / 1000000)Įxponent = :unc(:math.log2(bytes_per_second) / :math.log2(1024)) Then = :erlang.system_time(:micro_seconds) defmodule DownloadPerformanceTest '/dev/null' So my question is, what exactly is responsible for those slow download speeds, and are there any workarounds for it? I know of libraries like which use libcurl and therefore probably won't have the same issue, but I would prefer not to use any libraries that make use of NIFs. My guess is that it has to do with Erlang's socket performance, but I could be wrong. I tried using other HTTP libraries including ibrowse and hackney, but the same issue persists. (10.7 MiB/s or 85.6 MBit/s on a 100 MBit/s network interface). With curl and wget, CPU utilization stays slightly below 100% and it manages to almost fully utilize the network interface I'm running Erlang on an ARM-SoC which is only slightly more powerful than the first Raspberry PI, and this piece of code results in 100% CPU utilization and a download speed of only 6.1 MiB/s. The high CPU utilization is problematic especially on low-end devices. The code I'm using to measure the download speed can be seen at the bottom of this post. When downloading files via HTTP using Erlang's httpc, CPU utilization is much higher than with curl or wget, for instance. ![]()
