Ubuntu samba slow transfer speed12/15/2023 ![]() This sets the largest block of data that your Samba will try to write at any one time. In Samba this is basically related to the MTU and window size. The previous settings are mandatory as far as I know for this to work. These allow Samba to use large reads & writes on the network – up to 64KB in a single request. Try my values, maybe they work for you too! It usually helps but do note that at some point you reach diminishing returns. Same issue here with RPi4 - both samba and FTP transfers are 10MB/s, while external drive connected using USB3 is capable 100MB/s. It basically tells the server to send as many packets as necessary to keep the delay low.īasically increasing the send and receive buffers to something higher than present in the operating system. Re: Slow samba transfer speed on RPi4 to a usb 3.0 drive (10,4mb/s) Sat 1:27 pm. But it wont hurt to make sure it’s there. In Samba 2.0 this setting is the default. Mind you, the speed for transferring many small files at once is just about the same. So in just 2 minutes I gained about 20 MB/s extra speed when transferring large files. The results? Constant >110 MB/s topping at 114 MB/s on large files. Save, apply configuration (the top notification) and DONE! Socket options = TCP_NODELAY SO_RCVBUF=65536 SO_SNDBUF=65536 I tried everything from my end but the data transfer speed on SMB/CIFS are less then 3 MB. Simply place these extra configurations: Hi, I am getting deathly slow speed on my Raspberry Pi 4 with OMV 5.Tuning SMB within OMV SMB extra options for a quick speed gain ![]() Triple checking the install and the needed plug-ins for OMV (especially the flash plugin from omv-estras) there could only be one culprit for the speeds: SMB. And of course, we have some Docker containers for Plex and other stuff. This isnt directly an answer to the question, but its definitely a workaround I switched to NFS, where the transfer speeds are a lot faster, for no obvious reason. How we acces files on the NASīy using SMB withing Open Media Vault, we just use the normal file explorer within Windows 10. You’ll just have to edit the Samba configuration file instead of pasting something into Open Media Vault’s admin panel. I must say that these settings can work on SMB even if you’re not working with OMV and you are on Ubuntu or whatever. (if you want to read up about the difference between MB/s and Mb/s read here) After dabbling with any potential issues, even if our NAS is running from a Kingston 64GB USB drive, and has 1 250 GB SSD and a new 4TB HDD, it should theoretically reach at least 100 MB/s.
