This increases CPU load for the writing and occupies the disk. Check that logging is set to Errors/Warning only in the Status window.Įspecially the +Debug setting writes very frequently tiny bits of data to the disk.The cache will only be used when necessary, cache usages above 400MB are rare. If you download a lot of rar files that are 200MB or larger then use the latter value. Depending on how much RAM you can spare, two good values are 500M (the M denotes megabytes) or 1G (1GB). This will keep articles in memory until they can be written to the correct file instead of first writing them to individual temporary files which has to be read back later. Set the Article Cache Limit in Config->General.Divide the result from by 8 to get the speed in MB/s. Use a wired network connection, not wireless. For testing only: set the download to Download in Config->Categories, so no Repair, no Unpack at all.Turn off Unwanted Extensions in Config->Switches.This will disable encrypted transfer and reduce CPU load. More concurrent disk activity may reduce the speed. Turn off DirectUnpack in Config->Switches.SABnbd will first download, and after downloading it will start processing Turn on "Pause Downloading During Post-Processing" in Config->Switches.The following settings may help (in order of importance): If your focus is on pure high-speed downloading itself then you should let SABnzbd do downloading only (and not any simultaneous processing). If you are posting a question if you think your download speed is too low, post the info reported by the Wrench tool.Īdditional settings for high-speed downloading On a system with a CPU with at least 100,000 pystones, and SSD drives achieving 150 MB/s, a Gigabit Internet connection reported as 100 MB/s by SAB you should be able to get 100 MB/s newsgroup downloads. Start with a test download: Wrench -> Test Download -> 1000 MB.This may allow higher speed as they can all download at the same time. Use multiple news servers at the same priority.SABnzbd should report a pysthone of 100.000 or higher. Your CPU should be medium or high speed.Slower disks like HDD and NAS have a very negative impact on downloading speed: a slower disk means slower downloads. SABnzbd should report the speed of Incomplete and Complete at least 150 MB/s. If you have limited space then the Incomplete directory should be on SSD. Both Incomplete and Complete should be on a SSD/M.2/NVMe disk.Start with a test of your system: Check at Wrench -> Status -> Refresh symbol, and note the performance numbers reported, and check them against these required values: The bottom line for high speed downloading is easy: If you have a fast Internet connection (60MB/s aka 500 Mbps, and over) and are not getting the full speeds you require, you can try the following: Basic requirements for your system and Internet connection
