There's an option when you execute yscb to say how many clients
threads you want to use. I tried with 1/8/16/32. Those results are
with 16, the improvement 1vs8 it's pretty high not as much 16 to 32.
I only use one yscb, could it be that important?
-threads : the number of client threads. By defau
How many instances of ycsb do you run and how many threads do you use per
instance.I guess these ops are per instance and you should get similar
numbers if you run more instances.In short try running more workload
instances...

I don't know how YSCB executes the reads and if they are random and
could take advange of the cache.
Do you think that it's an acceptable performance?

What's the value for hfile.block.cache.size ?
By default it is 40%. You may want to increase its value if you're using
default.
Andrew published some ycsb results :

-0.98.0-vs-0.98.8.pdf
However, I couldn't access the above now.

Is there any result with that benchmark to compare??
I'm executing the different workloads and for example for 100% Reads
in a table with 10Millions of records I only get an performance of
2000operations/sec. I hoped much better performance but I could be
wrong. I'd like to know if it's a normal pe
