06. 07. 2010 Worker nodes reading from two Thors at about 800 MB/s

Some jobs managed to almost get the theoretical max out of two Thors. These were the highest throuputs I had ever seen from the Thor fileservers.

Mail from Lukas Baeni describing his jobs

Hi Derek

I had a look at my jobs from monday. These were pure ROOT jobs. I ran 4 analyses each split into 25 jobs (each job had to read 5 files).
So at one time there were maybe 25 different accessed files, each read by 4 jobs. This would give us the 90-100 dcap connections.
