While not v25 info.. v24.1.0 released with the below notable flag in it addressing this community topic: Performance issues with v24.0.2
Flag("remove-on-update",
"Dgraph implements a read-through cache (using Ristretto) to optimize query performance. On "+
"mutation, the new value is first written to disk and then updated in the cache "+
"before the transaction completes to ensure there are no stale reads during parallel "+
"transactions. In mutation-heavy use cases, it may be more advantageous to remove "+
"the cache entry on mutation instead of updating the value, as this executes ~14\\%"+
"faster on write. The new value will be added to the cache the first time it is "+
"queried, slightly delaying that read. To use this approach, set the --cache "+
"remove-on-update flag.").
