Hi Andrei,

do you mind making your tests again by using AB (Apache Benchmarking Tool, 
http://httpd.apache.org/docs/2.3/programs/ab.html)?

sorry I used jmeter, is it ok?

######################################3

Sergio:

I tested on the same box:
* with jmeter 2.4
* empty terrastore (all buckets removed, fresh restart, java warmed
up)
* single thread jmeter thread group
* on apache: request http://127.0.0.1
* on terra server: request http://127.0.0.1:8000
* total run size: 100K requests;

throughput results:
apache: 6500 / sec
terra server: 490 / sec

this is consistent with with my previous test;

thank you

Andrei.

Sure, JMeter is okay.
But again, Terrastore is meant to be multi-threaded, so you should actually run 
your tests with multiple threads.

yes, I get the "multi-threaded" part :-)

what I do not get is why it is 10 times slow on empty request for this simple 
use case?

I assume in this case terrastore:
* does not introduce cluster locks
* bucket list (map with buckets) is already cached
* everything is read-only

then it should be "instant", right? :)

like I mentioned - with terrcotta toolkit and native terrcotta maps 
I get close to apache speed;

well I guess this is just a request to take a fresh look on overall terrastore 
pipline;

and if piplene is pluggable, may be try to plug in some other guys:
http://www.restlet.org/
etc

Agreed: we should give other options, such as Restlet or Jersey, a try.
