This is not a qBittorrent bug/issue, it's a less known router performance issue most are not aware of.The Norton and LifeLock Brands are part of NortonLifeLock Inc. If you want to know how well a home router will handle P2P type traffic, look for "Maximum Simultaneous Connections" under the "Routing Performance" section of any router review. does some amazing reviews and benchmarking of home network products. Use this with a conservative max connection count setting of 200-500 and you should see some improvement. So you may get some glitchy network performance for a short period at the beginning which then subsides soon after. Turning DHT off in qBittorrent really helps with this, and it's smart enough to not disable it completely - it will use DHT for a short time when magnet links need to be resolved, then close all the DHT connections. So leaving DHT enabled will cause NAT table overload for most older or budget oriented home routers. Most torrent clients have a max-connection setting to help work around this issue, but so far I've noticed DHT doesn't care about this max setting. Bandwidth is still the same but router has no idea what's coming and going so everything starts to break down and kinda hobbles along sub-optimally. It also snowballs as the user's laptop reacts by trying to create more sessions and re-transmissions to compensate for the connection problems it's experiencing. Torrents and especially DHT nuke NAT session tables! Once the table fills up, the router cant keep up and starts dropping sessions constantly - this causes a lot of TCP and UDP sessions to get dropped constantly and slows down the user experience. So maximum session table size for many home routers are in the range of 1500-5000 and beyond if it's something more recent and beefy. This way when a packet comes back from a website or other server, your router knows it goes back to your laptop's internal LAN IP address (usually .y).ĭuring normal network usage maybe 50-200 sessions are established per device when active, and most home routers/gateways are designed to handle that for 10-20 devices. One less known variable is firewall/NAT performance, and this is one most Torrent clients HAMMER the proverbial crap out of.įor every TCP/UDP connection, your firewall/gateway/router has to create a table entry to maintain the session which tracks the inside/outside IP and port pairings for each session. On internet connections we tend to focus on bandwidth as a cause of performance issues. DNS lookups fail, web browsers constantly have connections time out and retransmit, some pages load but there are missing pictures. This causes a lot of dropped/misbehaving TCP and UDP connections which 'feels' like the internet is slow. TL:DR - Torrent clients can overload NAT tables on old/mid range home routers, especially with DHT enabled. I'm going to repost a comment here I left on a similar issue. However, I will admit, I have Bitdefender also, so disabling MB's Web Protection module does not leave me totally defenseless and I still have the other MB modules turned on.įinally, while turning off MB's Web Protection module seems to immediately solve the problem, you may want to reboot your machine after deactivating the module just to be sure the service is completely stopped. Since disabling their Web Protection module, everything has been fine. That wreaked havoc for me with qBittorrent, causing all sorts of issues from QB freezes, OS lockups, crashes, to even Security Kernel BSODs. I'm almost certain it's MalwareBytes and more specifically, their Web Protection module. So it is probably a software issue - either Windows 10/ or some other software interferring with qBittorrent like MalwareBytes 4.2.1 premium maybe? also I have the latest LAN drivers and utility for the mobo. Router is TP-Link Archer C6U connected with wire to my 2.5 Gigabit port on B550m Steel Legend
