I doubt it there are huge gains with tinkering if adding more CPU speeds
the things up, that indicates you're resource bound. It's over a VM, it's
probably a slow underlying disk, there is just physics at some point. You
can try playing with using the java client instead of the sstableloader but
I
Yes, I think so too. Plus, I used VM with 4 CPUs and 2 CPUs, and 4CPUs
really did faster.
But It took 1 hour to generate sstable for 1G csv. I am wondering if there
is other way to make it faster except adding CPUs and ram.

I think that'd be slow copying large files with just the cp command.
Cassandra isn't doing anything amazingly strange here, you don't have a lot
of RAM, nor CPU and I'm assuming the underlying disk is slow here as well.
Without more parameters and details it's hard to define if there is an
issue.
Hi, Everyone:
I'm importing a CSV file into Cassandra using SStableLoader. And I'm
following the example here:
https://github.com/yukim/cassandra-bulkload-example/
But, Even though the streaming of SSTables is very fast , I find that
generation of SStables is quite slow for very large files (CSV,
