[infinispan-dev] Fwd: still to do on HR-embedded integration in ISPN-2281

[Martin Gencur]

Hey,
so I have some good news. I've re-ran my tests for memory consumption 
where I store 100MB of data and here's the results for in-VM mode and 
client-server with HotRod:

Previously, the memory overhead for HotRod was (can be found at 
http://infinispan.blogspot.cz/2013/01/infinispan-memory-overhead.html):
entry size -> overhead per entry
512B       -> ~174B
1kB        -> ~178B
10kB       -> ~176B
1MB        -> ~245B

Now it is:
512B  -> ~159 (~ -9%)
1kB   -> ~159 (~ -11%)
10kB  -> ~154 (this is perhaps affected by the low number of entries 
stored in mem.)
1MB   -> ~184 (the same applies here)


For in-VM mode it was:
512B -> ~151B
1kB  -> ~151B
10kB -> ~155B
1MB  -> ~143B

Now it is:
512B  -> ~150
1kB   -> ~150
10kB  -> ~149 (this is perhaps affected by the low number of entries 
stored in mem.)
1MB   -> ~143 (the same applies here)


Summary: Almost no change for in-VM mode but a nice improvement for the 
HotRod client.

I can make a blog post once we have this for Memcached and REST. I guess 
it is not ready yet.


Cheers,
Martin
