<font size=2 face="sans-serif">Transferring the small files with AFM  +
NFS over high latency networks is  always a challenge. For example,
 for each small file replication AFM performs a lookup, create, write
and set mtime operation. If the latency is 10ms,  replication of each
file takes minimum (10 * 4 = 40 ms)  amount of time. AFM is not a
network acceleration tool and also it does not use compression.  If
the file sizes are big, AFM parallel IO and parallel mounts feature can
be used.  Aspera can be used to transfer the small files over high
latency network with better utilization of the network bandwidth.</font><br><br><a href="https://www.ibm.com/support/knowledgecenter/no/STXKQY_5.0.4/com.ibm.spectrum.scale.v5r04.doc/b1lins_afmparalleldatatransferwithremotemounts.htm"><font size=2 color=blue face="sans-serif">https://www.ibm.com/support/knowledgecenter/no/STXKQY_5.0.4/com.ibm.spectrum.scale.v5r04.doc/b1lins_afmparalleldatatransferwithremotemounts.htm</font></a><br><a href="https://www.ibm.com/support/knowledgecenter/no/STXKQY_5.0.4/com.ibm.spectrum.scale.v5r04.doc/bl1ins_paralleldatatransfersafm.htm"><font size=2 color=blue face="sans-serif">https://www.ibm.com/support/knowledgecenter/no/STXKQY_5.0.4/com.ibm.spectrum.scale.v5r04.doc/bl1ins_paralleldatatransfersafm.htm</font></a><br><br><font size=2 face="sans-serif">~Venkat (vpuvvada@in.ibm.com)</font><br><br><br><br><font size=1 color=#5f5f5f face="sans-serif">From:
