Re: [infinispan-dev] still to do on HR-embedded integration in ISPN-2281
Hmmmm, not the expected results. There's no way we should be consuming more memory per
entry. It should definitely be less, particularly for Hot Rod and Memcached and about the
same for REST. The fact that all of them grow seems to be there's an issue in the core
impl.
@Martin, can you generate a heap dump, say for Hot Rod (with 512b entries) at the end of
the test (when the cache is still populated)?
Cheers,

Hi,
so I gave it another try with latest Infinispan and Infinispan-server snapshots (HEAD:
a901168, resp. bc432fa) . In short, the results are still the same for inVM mode but worse
for client-server mode. Of course, I haven't changed anything in the test since last
time.
This time, I left out the results for 1MB entries because there's high distortion due
to the low number of entries stored in a cache (storing 100MB of data). Previously,
the results looked better for HotRod compared to the first round of tests I did for ISPN
5.2. Now the results for HotRod are worst of the three measurements, inVM mode remains the
same:
HotRod (ISPN 5.2):
entry size -> overhead per entry
512B -> 174B
1kB -> 178B
10kB -> 176B
HotRod (ISPN 5.3-SNAPSHOT, a few weeks ago)
512B -> 159 (~ -9%)
1kB -> 159 (~ -11%)
10kB -> 154 (this is perhaps affected by the low number of entries stored in mem.)
HotRod (ISPN 5.3-SNAPSHOT, now)
512B -> 191
1kB -> 191 (measured twice)
10kB -> 186 (looks a bit distorted already)
------------------------
Memcached (ISPN 5.2)
512B -> 184
1kB -> 181
10kB -> 182
Memcached (ISPN 5.3-SNAPSHOT)
512 -> 228
1kB -> 227
10kB -> 235
--------------------------------
REST (ISPN 5.2)
512B -> 208
1kB -> 205
10kB -> 206
REST (ISPN 5.3-SNAPSHOT)
512 -> 247
1kB -> 247
10kB -> 251
------------------------------------
inVM (ISPN 5.2)
512B -> 151
1kB -> 151
10kB -> 155
inVM (ISPN 5.3-SNAPSHOT)
512 -> 150
1kB -> 150
10kB -> 150
