TAC memory and cpu under utilized

[cdhemant]

Hello,

We tried to load TAC (4cpuX16gb, 8cpuX32gb, 16cpuX64gb ) with 3-4 jobservers(4cpuX6gb ram) No of jobs ran were from 100 to 200

However found that TAC was not efficiently utilized. its cpu and memory where used only 15 to 30%.

We did changes to below settings as per https://help.talend.com/r/en-US/7.3/installation-guide-windows/recommended-configuration

# quartz.properties

org.quartz.threadPool.threadCount = 30 (this value was changed to 30, 40 and 80 for different TAC VM configuration)

org.quartz.dataSource.QRTZ_DS.maxConnections = 30 (this value was changed to 30, 40 and 90 for different TAC VM configuration)

 # configuration.properties

hibernate.c3p0.max_size=32 (this value was changed to 30, 40 and 80 for different TAC VM configuration)

still there was no change on TAC utilization

is there any other setting by which we can improve TAC utilization as we want to execute large number of jobs 500 to 700

Thanks

Hi @not specified not specified​ 

I believe what you want to achieve is actually done by customizing JVM parameters for each of your Job Conductor tasks.

TAC serves solely as the "task/job caller." The fewer resources it uses, the better, as it allows for more resources to be allocated to the actual Jobs.
