Hi Craig, first of all thanks for your time. I have some guesses from what you said but I'd appreciate if somebody can confirm my thoughts please. Does the DISKCACHE value affects an in-memory graph scenario at all? Should I set it to 0 or it doesn't matter at all?
If the disk allocation doesn't affect the boot time, what could be impacting the boot time as I got over 1 sec to create an empty graph on memory? Can I specify internally (not through the JVM options) a % of available memory the graph should take?
