    <title>topic MD5 optimization to support Amazon s3 integrity check generation in Software Tuning, Performance Optimization &amp; Platform Monitoring</title>

    <description>&lt;P&gt;Amazon S3 uses MD5 for an integrity check on its data (note: non-security function so MD5 is ok -- I have no security issues with using MD5 for an integrity check).&amp;nbsp; Since this is their choice, for my on-premise data I am moving to and from Amazon using Intel Servers I am now computing MD5 using software -- no hardware assist. This work is taking up a good portion of my cloud cores.&amp;nbsp; Note that other object storage services like Swift also use MD5 so don't tell me to switch object storage services.&amp;nbsp; I talked with Amazon today and they mentioned that MD5 might be available with SHA-1 function now in SilverLake.&amp;nbsp; I can't seem to see anything like this.&amp;nbsp; Can you please let me know if this is the case?&amp;nbsp; And if it's not the case maybe Amazon and Intel can sit down and agree on an efficient, hardware-assisted integrity check algorithm?&lt;/P&gt;</description>
