Subject [jira] [Commented] (GIRAPH-514) DiskBackedMessageStores should take advantage of machines with multiple disks

Claudio Martella commented on GIRAPH-514:
-----------------------------------------

you're right, just re-checked. i just sent today a couple of jobs with very low max inMemory
messages (1000) and it was really slow at the end of superstep -1 (sending few kilobytes per
flush). I thought that might have been the reason when I quickly checked the code. I'll investigate
further. thanks!

> We are storing messages on a per partition on disk. We can store each file (partition
data) on a different disk, if available, to take advantage of full IO bandwith, when using
multiple compute threads or workers per machine.
