Hello.
I have a 8.10 version as a file server and 4.19 samba on a gigabit local network. Although coping on network is fast, accessing Access db files, is slow. The same files on a common win 11 pc is very fast.
I try socket options in smb.conf but the performance is worse.
Is there a suggestion?
Thank you in advance.
Nikos.
hi
Hi Nikos, the Samba smb.conf(5) manual warns that setting socket options overrides the operating system’s network tuning. On Linux in particular, auto-tuning of TCP buffer sizes can be disabled if you specify socket buffer sizes (e.g., SO_SNDBUF/SO_RCVBUF), which can seriously hurt performance. Since performance got worse after your changes, I’d recommend removing the custom socket options and going back to the defaults, then benchmarking again. If you still want to tune it, change one thing at a time and measure, because the docs note that incorrect low-level settings can degrade performance as much as correct ones can improve it.

Thank you for your answer.
We are starting to think that the problem has to do with Access communication from NTFS systems to Linux systems. We moved the whole program to Linux and it runs much faster. So it doesn’t seem to be a samba problem. Is that possible?
