escowles/longshou: do you have a take on whether the auto-transparent-hierarchy is feasible?17:08
<longshou>awoods: I think we can make it work but not sure what’s the side impact on the SPARQL result. Esme and I are thinking about doing the recussive getChildren() lookup first to see how the performance looks like.17:18
<awoods>longshou: ok. So you are currently working FedoraResource.getChildren()?17:19
<longshou>Not started yet but I’ll. I am trying to wrap wu the graphs for CRUD concurrent performance but seeing a weird result when starting with 32, 16, 8, 4, 2 threads. The result favors the 32 threads.17:22
<awoods>longshou: the result favors the 32 threads for all operations?17:23
<longshou>Two threads took longer response time. Could be some issues with the memory usage of my MAC. I am killing some processes to retest it.17:24
awoods: I am still geting a similiar result with the same trend. 32 threads delete object 22 ms, delete content 24 ms, while 2 thread delete object 153 ms, delete content 366 ms. It could be the result of records accumulating up that dominates the test. Any ideas? How about starting from 1, 2, 4, 8, 16, 32 and discard the result for 1 thread to draw the graphs?17:44
<awoods>longshou: You are seeing different numbers if you run the test in opposite order? [1, 2, 4, 8, 16, 32] vs. [32, 16, 8, 4, 2, 1]17:47
longshou: if so, it seems like an issue with the test.17:48
<longshou>Yes. A result that is harder to explain.
<awoods>longshou: it is not a problem, so go ahead and run the test both ways and document the results.17:54
<longshou>Sure. Thanks.17:56
