What is the maximum amount of memory that Urchin can use?
Urchin Software can use a maximum of 512 MB of memory. This can only be achieved by manually configuring the memory storage.
When setting a custom memory usage there are 5 data buffers that can be configured. Each data buffer corresponds to the data tables that Urchin stores report data to. The buffers are:
Visitor Buffer Size
Data Buffer Size
Session Buffer Size
Data String Buffer Size
Path Buffer Size
I recommend that you use the same ratio that is available by default in the custom memory storage settings. So if you increase the “Visitor Buffer Size” 5x larger, then increase all the other memory settings 5x high as well.
