st: Unix stata big dataset

[ncdcta00@uniroma2.it]

Dear Statalist,
I have a problem to joinby 2 datasets in unix, I have a dataset about  
1,8 gb and other about 30 mg, I want to join this two dataset but in  
unix is very slow the process, and in 4 days I did'nt have a final  
dataset ( two month ago I join two dataset, more o less the same size,  
in only 1 day). I use a do file where I write my command joinby.
I look with the command top at the processor in local machine and my  
process is in state sleep. I use batch mode
11258   franz   1  20    0    0K    0K cpu/0   35.8H 24.41% stata
 15566 ncd    1  20    0    0K    0K cpu/1   11:52 23.41% xstata
 16084 ncd  1  60    0    0K    0K sleep   27:00  0.22% stata
so, if my processes is sleep means that it no functions? there is  
another user connected, can he influence my process?
thanks in advance for your help
