Explanation

About Global Cache Block Access Latency Chart If the Global Cache Block Access Latency chart shows high latencies (high elapsed times), then this can be caused by any of the following: A high number of requests caused by SQL statements that are not tuned. A large number of processes in the queue waiting for the CPU, or scheduling delays. Slow, busy, or faulty interconnects. In these cases, check your network connection for dropped packets, retransmittals, or cyclic redundancy check (CRC) errors.
