Hi, all, 

i try to check the performance of Map/Reduce of Gluster File system. 

Mapper side speed is quite good and it is sometimes faster than hadoop's map job. 

But in the Reduce Side job is much slower than hadoop. 

i  analyze the result  and i found the primary reason of slow speed is bad performance in Merging stage. 

Would you have any suggestion for this issue

FYI check the blog http://storage4com.blogspot.com/
