Hi guys,

Hope you are well.

I was trying to run it using multiple threads, but I notice that it doesn't really matter if I use 1 or more, the program runs always with the same speed. Can you think of any possible reason?

Here is the command I run: sudo java -jar /opt/Trimmomatic-0.39/trimmomatic-0.39.jar SE -threads 12 -trimlog trimlog_fileX.txt fileX filtered_fileX ILLUMINACLIP:TruSeq3-SE.fa:2:30:10 LEADING:3 TRAILING:3 SLIDINGWINDOW:4:15 MINLEN:15

Am I doing something wrong? Is it on the Java VM side?

Thanks in advance for any insight.

-Jesse
