I have TL 2013 on i5 machine with 8GB RAM on Ubuntu 12.04.
I have downloaded the files and tested by unloading some packages you have
provided and found that the package "*titlesec*" is slowing down the
compilation when you go through tex4ht (make4ht). I have commented it on
*my_core.tex* and executed your *compile.sh. *The process is now faster.
Could you please check this.
I have not gone in detail on what is causing the problem in '*titlesec'*
package on tex4ht.
