Among the various tests it is capable of performing, there are a couple that are relevant to Digital Asset Manager (DAM) performance.
Assuming that your current working directory contains toughday-5.5.jar, the following command will upload 1,000 112 KB 849px x 565px JPEG images to CQ DAM and report the elapsed time (about 4 minutes on a server with 8 CPU cores and solid state drives).
java -Xmx2048m -Dhostname=yourcqserver.domain.com -Dport=4502 -DuploadImage.count=1000 -jar toughday-5.5.jar uploadImage
Please note that the renditions workflows triggered by the ingestion of these images will last a lot longer than the reported elapsed time, especially if the server CPUs are under-powered. At least two CPU cores are needed for a valid test.
Created images are NOT deleted after the test. They will be created under /content/dam/ with 50 images per folder with names such as /images1880.
The following command will upload 1,000 556 KB PDF files to CQ DAM and report the elapsed time (about 3 minutes on a server with 8 CPU cores and solid state drives when Tough Day is run locally, about 6.5 minutes when Tough Day is run remotely on another machine, ping delay 1 ms, 1 hop).:
java -Xmx2048m -Dhostname=yourcqserver.domain.com -Dport=4502 -DuploadPdf.count=1000 -jar toughday-5.5.jar uploadPdf
Created PDF documents are NOT deleted after the test. They will be created under /content/dam/ with 50 PDFs per folder with names such as /pdf7498.
This operation is CPU-intensive - see screenshot of Windows Task Manager below:
If you get the following WARNING message in error.log (reached maximum number of queued asynchronous events):
*WARN* [220.127.116.11  POST /bin/wcmcommand HTTP/1.1] org.apache.jackrabbit.core.observation.ObservationDispatcher More than 200000 events in the queue java.lang.Exception: Stack Trace
re-start CQ with the following additional JVM init argument in the start script:

NOTE: The following command will run all of the “Tough Day” tests (for Web Content Management [WCM] as well as Digital Asset Management [DAM]):
java -Xmx2048m -Dhostname=yourcqserver.domain.com -Dport=4502 -jar toughday-5.5.jar all
On a server with 8 CPU cores and solid state drives (SSD), this complete test suite should finish in about 6 minutes (Tough Day running on same server - no network latency). With Tough Day running remotely (thus incurring network overhead), it took 23 minutes on a server with 4 CPU cores and mechanical hard disks (HDD).
On a desktop with 2 CPU cores and mechanical hard disks (HDD), this took about 14 minutes (Tough Day running on same server - no network latency).
Essentially, if this particular test takes longer than 30 minutes on your server hardware, you should identify and address potential performance issues before deployment to production.
