hi, all: I'v got a Gluster testing, and found some performance issuse pertain to Gluster I built a ten-node Gluster enviroment, (3 X HP 380G5, 4 IBM 3650, 2 X HP C7000. 1 X DELL PE2950, all the network switch & NICs are all gigabit). And set up three volumes: a ten-brick distribute volume (ten-brick means this volumes resides on ten nodes, others are same), a five-brick distribute volume, a ten-brick distribute replica volume And I copied a folder ( including about 100 files, the size of everyfile is 40MB~80MB) to these three volumes one by one, and found the average speeds are: to ten-brick distribute volume : 25MB/s to five-brick distribute volume: 50MB/s to ten-brick distribute replica volume: 10MB/s Who have any idea about: Why the performance is so bad? Why the performance of ten-brick distribute volume is worse than five-brick's(technically ten-brick volume should be better than five-brick volume)? How to tune it? Thanks Tide Lui
