Once your validator is operating normally, you can reduce the time it takes to
restart your validator by adding the `--no-port-check` flag to your
`solana-validator` command-line.
### Using a ramdisk for the accounts database to reduce SSD wear
If your machine has plenty of RAM, a ramdisk
([tmpfs](https://man7.org/linux/man-pages/man5/tmpfs.5.html)) may be used to hold
the accounts database.
Assuming your tmpfs ramdisk is mounted at `/mnt/solana-accounts` and writable
by the validator user, add the `--accounts /mnt/solana-accounts` argument to
your validator command-line to use it. Once your validator restarts, you should
now see activity in `/mnt/solana-accounts` instead of the `accounts/`
subdirectory of your ledger (`--ledger` argument) directory.
For Mainnet Beta it's recommended that a ramdisk of 64GB be used. Note that if
your machine has less than 100GB of RAM in total, using a ramdisk is not
recommended.
