Cześć Aleksander,
node with mfsmaster & chunkserver:
CPU - E5440 - 8 cores, 2.83GHz
$ free -m
               total        used        free      shared  buff/cache   
available
Mem:           3946        2497         136          64        1312      
   1067
Swap:          4091        1322        2769

second node with chunkserver:
CPU -  X3230 - 4 cores, 2.66GHz
$ free -m
               total        used        free      shared  buff/cache   
available
Mem:           1998         426          81          36        1490      
   1345
Swap:          2043        1436         607


Both nodes uses 7.2k HDD, nodes are connected using 1GB ethernet. This 
is local LAN, ping is below 0.2 ms.
Problem with data access is on second node.
I'm going to add more chunkservers but I have to migrate services from 
phisical machines to VM. I can't do it because I'm observing stability 
problem...
