it seems that *.fdt is readed and stored in block of 16KB, i
I would first try upgrading you JVM: 1.7.0_05 is ancient.

Hi ,all

my machine spent too much time(10-20 hours for a index size of 15GB). By using
some command like top, iostat, jstack. I found that the avg of cpu, and disk is
too low, nearly zero. And the size of the the inde
