Introduction to the proxy_temp_file_write_size parameter
In Nginx, we can easily use the ngx_http_proxy_module module for performing reverse proxying. One of the most interesting features provided by this module is the proxy_temp_file_write_size parameter. This parameter allows us to control the size of temporary files used for caching proxy data.
If we are using Nginx as a reverse proxy server, we may want to cache data received from the origin server. Here, the size of the temporary file that Nginx needs to write this data to disk is important. If this size is not configured correctly, we may encounter issues with caching data or the overall performance of the server.
This parameter is set to 8KB by default. Therefore, if you process a large volume of data, you might want to increase this amount to avoid repeated writing to disk, which can negatively affect system performance.
Thus, configuring proxy_temp_file_write_size can help you better control Nginx behavior and ensure it aligns with your specific needs. For example, if you receive files that are large, you might want to increase this parameter’s size to ensure more reliable processing.
Example configuration for this parameter
http {
proxy_temp_file_write_size 64k;
}Code explanation
http {
This line specifies that we are configuring a block of http. proxy_temp_file_write_size 64k;
Here, we increase the size of the temporary file to 64 kilobytes. This tells Nginx that it can cache larger data in one write to disk.}
This line closes the http block, completing our configuration.
