Highspeed Downloading
If you are blessed with a fast connection (20MB/s and over) and are not getting the full speeds you require, you can try the following:
- Set the article cache in Config -> General. This will keep articles in memory and not write them to disk (which is slower). Depending on how much RAM you can spare two good values are 70M or 120M (the M denotes megabytes and is required). If you download a lot of rar files that are 100MB or larger then use the latter value.
- Make sure python-yenc is installed (yenc-0.3.tar.gz or higher). If you are on windows it will already be present. This will speed up decoding as it will use C code instead of python code. The logging will say at startup whether this module has been installed. If you have installed using a repository/pre-built package you will likely already have it.
- Lower your connection count in Config -> Servers. It may seem counter-intuitive, since more connections should be faster than fewer connections, but if you use the 50+ connections some hosts give you the overhead from constantly opening and closing connections can slow you down. So start at the max allowed connections and slowly lower your count until you max out your speed.
If none of the above methods make a difference, have a look at how much CPU is being used while downloading, if it is at 100% it is likely your processor is too slow to maintain high enough speeds.
