If you are not experiencing the download speeds expected, please try the following:
1. For the fastest download speed we always suggest using a wired internet connection rather than wireless wherever possible.
2. For custom installs, make sure sabyenc is installed by reviewing the first page of the Config file.
- All installations from installers or pre-built packages will have this in place by default.
- Most users will not need to verify this.
3. If the hardware you’re running SABnzbd on has a lot of RAM, you can improve processing speed by not writing files to disk, saving time and processing power.
- You can adjust this via the Article Cache Limit setting in Config->General.
4. Review your Errors/Warning logging settings in the Status window. If set to in the +Debug setting, you will have a higher CPU load.
- To change this setting, click on the wrench icon to access the Status settings. The dropdown option in the lower right should be set to “+info”. If it is set to “+Debug”, please change it.
5. To reduce the amount of CPU power required for large queues, review the “Only Get Articles for Top of Queue” setting in Settings->Config->Switches, and update as needed.
6. Occasionally, a higher number of connections can actually slow down your speeds for users on slower connections or older computers. If you’ve encountered speed issues, we suggest to slowly lower your connection count until you max out your speed.
- The connection count setting can be found in Config->Servers.
7. You are able to change the TLSCiphers. Updating these can greatly increase download speeds but may lower encryption strength. This is suggested for power users only. SABnzbd has a guide on this process.
Additional Speed Optimization Tips
- The following suggestions should additionally assist in increasing download speeds:
1. We recommend SSD drives are for all download folders, both complete and incomplete. Use of slower drives such as NAS and HDD may increase processing times.
2. Activate "Pause Downloading During Post-Processing". You can find this in Settings ->Switches in the Post Processing section. Once activated, SABnbd will download the files completely, then begin processing, instead of doing both at the same time.
3.Deactivate DirectUnpack. This is found in Settings->Switches in the Queue section.
4.Deactivate Unwanted Extensions and Encrypted Downloads. This is found in Settings->Switches in the Queue section.
