Are there ways to degrade the performance of data deletion from an index?

To degrade the performance of the data deletion process from an index (for example, in search engines or databases), one can:

• Delete data one item at a time rather than in batches, which increases the number of operations.
• Frequently perform deletion operations without subsequent optimization or segment merging.
• Use synchronous deletion operations that block the main thread.
• Avoid caching or buffering during deletion.

In real-world tasks, the opposite is usually aimed for—optimizing deletion—but understanding ways to worsen it helps identify bottlenecks.
