[svn-r11522] Purpose:
Increase metadata cache max size / min clean size from 4/2 MB to 8/4 MB.
Description:
One of our users on copper had a performance bug caused by the 4/2 MB
cache size in 1.6.4. Increasing cache size to 8/4 MB solved the problem
for him.
Solution:
Since the metadata cache size is still hard coded in 1.6.5, increasing
the size to the largest value we have seen needed in the wild seems
prudent. This commit tends to this issue.
Platforms tested:
Serial test on Heping.
