I am new to ZFS and would be glad if anyone can help me with the following query.
We are using the ZFS pool for our Backup and restore services and we access the files on need basis. The problem is the first time reads are very slow (getting 1.15 GBps read throughput) and we are getting very good read throughput while accessing the same files second time( disk reads are very minimal in second time and getting 20GBps throughput). Is there any process or command to put the files in memory at NAS server side before the start of application access. we have plenty of RAM available at NAS servers( 4 nas servers * 230 GB) and RAM may not be an issue for us.
Appreciate your help in advance.
