Hi, and welcome to the forum!

That’s a good question!

Disk is so cheap now that most folks don’t set PCTUSED.

This may help:


For massive inserts, set PCTUSED to a high value, so only dead empty blocks are placed on the free list.

Actually, blocksize and average row length matters the most!

Remember, disk I/O is the single most expensive operation in any database.

Cache frequently used data!
