This essay has presented the top 3 ways for you to solve Windows file share slow performance. You can apply to each one of them to tackle this task with ease and improve the file transfer efficiency.
How to fix Windows Server 2019 slow file sharing
I am having a weird issue where my server 2019 domain controller that is hosting a file share cannot send files over the network at more than 30mbps I have a gigabit card in there and it has 4 vCPUs and 10 gigs of RAM in never was this slow before it just started doing it. Does anyone know a better way to resolve the issue?
- Question from Microsoft Ignite
If multiple computers are on the same LAN, file sharing is usually set up to share resources, facilitate the transfer of information, and improve work efficiency. However, some users find that accessing shared folders is slow after using the file sharing function in the computer system. What are the causes of this situation?
Computer processors, memory sizes, hard drive read/write rate, remaining hard drive space, etc. can all contribute to slow file sharing. For example:
♣ CPU. To share small files, most computers do not make much difference, but encounter large files, of course, the better the processor, the faster the transfer. ♣ Memory. The larger the memory, the smoother the operation. ♣ Hard drive. The reason why the hard disk is upgraded from IDE to SATA is to improve the speed of transmission, so the hard disk interface has an impact. ♣ Network: Of course, if it is a remote transfer, but also related to the speed of the network. If it is within the same partition, the transfer is definitely faster, and the speed between the same partition is much faster than the transfer speed between partition and removable storage.
So is there any way to solve such an issue? Don’t worry, in this post, you will gain the most effective 3 ways to settle this problem effortlessly.
Since you already know the possible causes of slow Windows Server 2019 file transfer speed, now you can choose one of the 3 methods I have summarized for you to boost the speed of server computer file sharing. Here, you are allowed to change the system settings by disabling Large Send Offload and NetAdapterRSC, or you can directly rely on a professional third-party tool to make it faster to share files. Choose one that suits you most according to your needs.
Large Send Offload is a technique for improving network performance while at the same time reducing CPU overhead. Apparently, it does not work very well, so it is suggested to disable it. I’ll show you how to work on it.
1. Go to Control Panel> Device Manager> Network Adapters.
2. Under Advanced tab, select Large Send Offload V2 (IPv4) and set the value to Disabled. Do the same for Large Send Offload V2 (IPv6) if it is available.
Receive Segment Coalescing (RSC) is an offload technology that can help reduce how much of the CPU is used in network processing, which may also be one of the reasons that cause slow file transferring.
Follow the steps below demonstrating running the Disable-NetAdapterRsc on a Server 2019 machine with minimal loss of pings and file transfers auto restarting.
1. Run Windows PowerShell as Admin, check if AdapterRSC is enabled using this code: GetNetAdapterRSC. True=Enabled and False =Disabled.
2. If it is True, type the code disable-netadapterrsc to disable AdapterRSC.
3. Check again to confirm that is successfully disabled using the code GetNetAdapterRSC.
With the above treatment, Windows Server 2019 users can access the shared files on the LAN again after restarting the computer and you will find that the speed immediately improves a lot and double-clicking into the shared files is no longer slow.
If you deem that it is a hassle to change these settings, you’ve tried these methods and they still don't work, or you want to find the easiest and most effective way to prevent being hassled by this issue again.
