Fast Deduplication was developed by Klara Inc and iXsystems and offers up to x20 greater performance.
“With the introduction of Fast Dedup, there have been several major innovations including:
- The size of metadata is now dynamically sized to fit in either RAM or dedicated flash devices to avoid hitting the performance penalty wall.
- The metadata structure has been completely re-engineered to enable efficient updates using a log append process, greatly improving performance for large updates such as deletions.
- The dedup table will favor dedup-able data and prune blocks that show no dedup potential.
- Combining metadata improvements with properly configured storage, including dedicated metadata flash devices, will improve the sustained dedup performance by over an order of magnitude for larger systems.”
Some users are sceptical about potential data loss issues, as with any filesystem technologies..

String processing is essential in many UNIX commands. C strings are terminated with nul characters.
Routines processing such strings, such as those provided by the C standard library libc are often reduced to walking through strings character by character in search for the nul terminator. This is why these operations have the reputation of poor performance.
The FreeBSD Team has been working in a reimplementation of libc string functions using SIMD techniques and getting advantage of instruction set extensions by new CPUs.

This problem came up today. Adding a udev rule solved the issue:
cd /usr/lib/udev/rules.d/

Use of a hash algorithm in patient’s sensitive information (Name, Date of Birth or Social Security Number) using salt has the advantage of de-identifying personal data and also yields a unique identifier. This unique identifier can be later used to compare the disease course or follow ups in a different clinic. On the contrary an alphanumeric code can not re-identify these individuals.
