You can adjust the VM usage between 5 and 20 percent. It is recommended that you adapt this setting to the
amount of memory you have installed on your system. 5 percent is recommended any time your installed
RAM is less than 128 MB. This setting will affect performance on low end systems, if you are running anything
slower than a 500 MHz processor you should reduce the buffer allocation to a minimum. After you have made
adjustments you will need to restart NexStorm for the new settings to take effect.
Internal memory buffer information holds information about the purging of the memory buffer. Every once in a
while, NexStorm will clean out the buffer of strikes that are older than the maximum persistence setting of 300
minutes. As these strikes cannot be displayed anyway, there is no need to keep them stored in memory.
Purging will improve performance by allowing NexStorm to iterate through a smaller amount of records when
plotting strikes on the map as compared to if the buffer was not purged. You can see at what time the buffer
was purged and when the next purge will occur. After a purge has been done, you should see NexStorm
buffer usage decrease a bit, the amount will depend on the number of records that were purged.
Lastly, keep a watchful eye on the Disk usage bar. This indicator shows you how much space is used on the
hard drive unit where NexStorm is installed. If the disk starts becoming full, the bar will turn yellow to alert you
of this. At this point you should seriously consider removing unused files to free up disk space, NexStorm will
not be able to run if it has insufficient disk space for storing its data.
