Hi, I make some performance test on samba used as a openAFS gateway to windows world. The production environment is composed by: - 3 AFS Server (Linux) - 2 Samba GW (Linux)
The samba servers export the afs cell to the windows clients. The test was divide in 3 main part : 1) Linux client Performance on AFS filesystem 2) Windows Performance on remote share exported from linux samba server, where the share is a local disk 3) Windows Performance on remote share exported from linux samba server, where the share is a afs fileystem In this picture http://www.beolink.org/downloads/afs-performance/read-speed.jpg we have reach the same speed ( we are in warm cache condition). The strange things is on the write operation : http://www.beolink.org/downloads/afs-performance/write-speed.jpg, the difference btw case 2 and 3 is 50% of the speed. At the moment we didn't find a good reason for this performance reduction, we have made many different test with different chunksize, but nothing is changed. .. I'd like to know if someone has similar experience bye manfred
