I have a ubuntu VM of 12.04 server virsion and it is running on centos.
VM have 8GB of RAM and 1 core processor for it.
I amd running following application on it
hadoop 1.0.4 hbase-0.94.12 Intellicus (BI tool)
i observe a strange problem with my system all the application are running very slow.
here is the output of some commands i fired
free -m total used free shared buffers cached Mem: 7987 2351 5635 0 166 894 -/+ buffers/cache: 1290 6697 Swap: 4091 0 4091
I have Preload installed on it for performance boost but nothing really working for me and the host is having sufficient memory approx 23 GB free.
how can i increase the ram and run them faster
i have heard that incense the RAM and application will run faster but it isn't true
i have seen the similar question here but not working in my case
