I do datamining, and the first thing learned is that 80% of this wonderful science is datapreparation. I am looking for cheap wais to manage large about of data, and today i want to try how a RAM disk in Linux performs to create a dataset for weka.
As root, i want a 10MB file (yes, even though it is far away from being big data, the data preparation was taking several minutes)
root@talento:~# mkfs -q /dev/ram1 10240
root@talento:~# mkdir -p /ramcache
root@talento:~# mount /dev/ram1 /ramcache
root@talento:~# df -H | grep ramcache
/dev/ram1 11M 95k 9.6M 1% /ramcache
