> There seems to be a performance issue when using the LRU option.  With the attaches test, the 100,000 item Get takes 1200ms with LRU and 800ms without any config loaded.  I also noticed the put is slower.  
> get, put, remove
> 2704	1187	625     configured
> 2204	812	625     not configured
> For comparison I used a LinkedHashMap configured as LRU and get these figures:
> 1370	184	172
> Is this an issue with my configuration? Or a problem with how I'm using the cache?
