Investigate Linux readahead for VM coldstart

XMLWordPrintable

    • generic
    • linux

      Rescued from the closed RFE 6176136, this might be worth investigating:

      From ###@###.###:

      >> The latest versions of linux have something /usr/sbin/readahead
      >> <filename>, /etc/readahead_early.files, and sys_readahead(fd, foffset,
      >> count). Of course that makes we wonder if we couldn't accelerate
      >> coldstart by jamming a list of JVM files into the list in /etc. Adding
      >> the right sys_readahead() calls to the JVM itself might work, too,
      >> although I suspect that thread readahead operation might not be able to
      >> get far enough in front of the JVM's execution to do much good.
