6000+ NVPS
3570757 Items, 1609610 Enabled

When we reach approximately 75000 to 80000 Active Checks in queue > 10 minutes, we begin to see a delay in values. This usually presents itself as graphs not being updated with any values, and "Latest data" being delayed.

Alongside this we also notice that this can occur when the Buffers (History) size grows to approximately 1GB (2GB allocated). In fact, when we reach the problem number of Active Checks in queue, History Buffer starts to climb significantly.

See attachments for screenshots of current NVPS and History Buffers. More information can be provided on request.
