What is the fastest MD5 sum calculator?
- by netvope
I tested the speed of md5sum on a few Ubuntu 8.04 servers
Pentium III 700 MHz: 52 MB/s
Atom 1.6 GHz, 32-bit: 119 MB/s
Core 2 (Yorkfield) 2.5GHz, 32-bit: 194 MB/s
Core 2 (Yorkfield) 2.5GHz, 64-bit: 222 MB/s
Then I downloaded a tool (by apt-get install) called md5deep and found that it's roughly 20% faster (as tested on the 32-bit Core 2 server). This makes me feel that the "vanilla" md5sum included in Ubuntu isn't the fastest one.
Questions:
Other than md5deep, are you aware of any MD5 calculators that are potentially faster than md5sum? (Answers for software from other OS are also welcomed.)
If I want to compile md5sum myself, where can I download the source? What compiler options would you suggest for the Core 2 server? (note: gcc 4.2.4 in Ubuntu 8.04 does not seem to support -march=core2)
