@ -20,7 +20,7 @@ readCost = ceiling(bytesRead / CLIENT_KNOBS->READ_COST_BYTE_FACTOR);
The "page cost" of a write operation is computed as:
```
writeCost = SERVER_KNOBS->GLOBAL_TAG_THROTTLING_RW_FUNGIBILITY_RATIO * ((bytesWritten / CLIENT_KNOBS->WRITE_COST_BYTE_FACTOR) + 1);
writeCost = SERVER_KNOBS->GLOBAL_TAG_THROTTLING_RW_FUNGIBILITY_RATIO * ceiling(bytesWritten / CLIENT_KNOBS->WRITE_COST_BYTE_FACTOR);
```
Here `bytesWritten` includes cleared bytes. The size of range clears is estimated at commit time.
