Samba share very slow for a few days

Hi,

I am running a samba file server on my local gigabit network.  The server is running arch linux, and usus a RAID5 storage and a quad core CPU.

My desktop client is running Arch Linux too, and Windows 7 (Dual Boot). In the arch installation, I mount the samba shares via cifs in fstab (defaults, only specifying user credentials).

Until a few days ago, I got read and write speeds of ~110-130MB/s. I know that my issue was not present until a few days ago, as I was benchmarking cifs vs sshfs.

Yesterday I noticed that the samba mount occasionally hangs / freezes my file browsers when I browse or copy files to a samba share (in Arch Linux desktop client). Reading from the share is still OK (~110MB/s), but writing to the share is working with ~10MB/s. I'm sure that it's my client, because using WIndows 7 on the same physical machine, everything works fine. Copying to the share from Windows 7 still works with ~110MB/s.

I am confused about the huge performance decrease on my arch desktop client. I read the pacman log, but could not find any upgrade which could make trouble imo (maybe most recent kernel upgrade?). Does anybody else suffer from this issue? I did not change any system configurations, as far as I can tell. As a workaround, I switched to using sshfs, which works fine, but is slower than cifs due to server's CPU limitation.

Best wishes

Could this be related?
