Do you know how to clear cache in Neo4j?

[i***@public.gmane.org]

Hi~~~

I have done some test for benchmarking purposes in Neo4j.

But, I got some different result because I didn't remove(clear) cache.

So, I have found a method about flushing cache
"http://lists.neo4j.org/pipermail/user/2010-December/006049.html"

However, it is old version.

To clear cache, what should I do?

Thanks a lot

Why would you want to clear the cache?

Cold / uncached performance is not what you aim for in production settings.

He just told you why.

I'd be interested in knowing how to clear that cache as well, for the same
purposes.

Thanks,

I think Michael's question was more to ask why there is value in measuring
uncached performance at all. In production, caches are typically in play
and so the performance statistics for warm caches are far more useful for
comparison purposes.

Neo4j Enterprise edition features JMX beans for NodeCache and
Relationship cache. These beans have a clear() method that clears the
respective cache, see
