Buffer cache writes due to setting of the obsolete parameters "fast_start_io_target", "log_checkpoint_interval" and "log_checkpoint_timeout" were consuming significant database time.

oracle recomeneds as follows

Oracle's recommended solution is to control MTTR setting using the "fast_start_mttr_target" parameter instead of the "fast_start_io_target", "log_checkpoint_interval" and "log_checkpoint_timeout" parameters.

please advise.

If you want to understand more of what oracle is recommending, do some googling.

The link above is a start anyway but I ain't doing your work for you.

Good luck, Kevin
