snapraid v11.5 by Andrea Mazzoleni, http://www.snapraid.it
Compiler gcc 9.3.0
CPU AuthenticAMD, family 16, model 5, flags sse2
Memory is little-endian 64-bit
Support nanosecond timestamps with futimens()

Speed test using 8 data buffers of 262144 bytes, for a total of 2048 KiB.
Memory blocks have a displacement of 1792 bytes to improve cache performance.
The reported values are the aggregate bandwidth of all data blocks in MB/s,
not counting parity blocks.

Memory write speed using the C memset() function:
  memset    4045

CRC used to check the content file integrity:
   table    1167
   intel

Hash used to check the data blocks integrity:
            best murmur3 spooky2   metro
    hash spooky2    2036    4067    3941

RAID functions used for computing the parity with 'sync':
            best    int8   int32   int64    sse2   sse2e   ssse3  ssse3e    avx2   avx2e
    gen1    sse2            4812    5063    6197                        
    gen2   sse2e            2231    3201   »5059«   3683                
    genz   sse2e            1204    2128    3721    4014                        
    gen3    int8     425                                        
    gen4    int8     312                                        
    gen5    int8     259                                        
    gen6    int8     230                                        

RAID functions used for recovering with 'fix':
            best    int8   ssse3    avx2
    rec1    int8     223
    rec2    int8      40
    rec3    int8      28
    rec4    int8      18
    rec5    int8      13
    rec6    int8      10
