TOS : consumption and optimization CPU

Anonymous — Mon, 22 Aug 2016 08:38:22 GMT

Hi,
would you have any informations about CPU's consumption and optimization. I explain my case:
I work with TOS 5.6.2, i have one job witch launch forty sub jobs sequentially because each job depend on the next. My job spend 2h
When i saw my CPU's consumption, i use 50%, but i launch my job on dual core platform. So my real consuption is 100% for first core and 0% for second core.
I search a way to optimzise my consuption to have 100% for each core to reduce the run time.
I saw some post about multi threading but it concerns some jobs witch we can parallelize. In my case, moslty of my sub job can't be launch in parallelize mod.
have you any idea plz.
thx.
