# This script runs first the RUBBoS browsing mix, then the read/write mix 
# for each rubbos.properties_XX specified where XX is the number of emulated
# clients. Note that the rubbos.properties_XX files must be configured
# with the corresponding number of clients.
# In particular set the following variables in rubis.properties_XX:
# httpd_use_version = Servlets
# workload_number_of_clients_per_node = XX/number of client machines
# workload_transition_table = yourPath/RUBBoS/workload/transitions.txt 
#
# This script should be run from the RUBBoS/bench directory on the local 
# client machine. 
# Results will be generated in the RUBBoS/bench directory.
