Large amounts of RAM

[cp2]

Has OrientDB been tested with very large amounts of RAM and very large graphs?

By large, I mean 1/2 TB to 1TB range.

If so, how is performance? 

How is Garbage Collector overhead?

Hi,

We did not test with such large memory but we use direct memory for data caching, not java heap.

So GC does not provide any overhead because it does not exist in our data caching solution (I mean low level cache system which is used bellow of our index and cluster data structures).

If you have chance to test it using such large memory I will be really appreciate if you publish results.

But I am absolutely sure that we do not have any GC pauses because (sorry that repeat this) we do not use Java heap.

I did not realize you were doing direct memory access. This is very good.

I was hoping someone had already done this test *prior* to our investing in such an expensive bit of hardware. :)
