[jira] [Updated] (ORC-175) ZLIB performance

     [ https://issues.apache.org/jira/browse/ORC-175?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

iamhumanbeing updated ORC-175:
------------------------------
    Description:     (was: The Intel® Intelligent Storage Acceleration Library (Intel® ISA-L) is a collection of optimized low-level functions used primarily in storage applications, but given the flexibility inherent to low-level implementations, ISA-L has ramifications for software well beyond the storage domain. The open source versions contain multiple units that include functions to implement fast erasure codes, data protection & integrity, compression, hashing and encryption. 
We used ZLIB code of ISA-L to get 200% compression improvement and 50% decompression improvement for ORC FILE. )
        Summary: ZLIB performance  (was: Using compression code of Intel® ISA-L to improve ZLIB performance)
