GCS on grid control graph is high and write data slowly
We writed more data to Oracle RAC 10.2 + ASM on Redhat.
It's slowly. When we check grap on Grid Control, we found high stat on "Global Cache Block Access Latency".
How can I tune or investigate?
###remark
Oracle Cluster 4 nodes (10.2 + ASM on redhat 4)
interconnect CAT 6 (1G) and use bonding
