Since you already store tbench_name and tbench_tar, perhaps you should just encode them into tbench_url rather than hardcoding again.

tbench is also available in the repositories for common major distros. What about before falling to downloading and compiling it you first try to grab package from apt/yum?
Something similar to this:
if apt policy tbench 2>&1 1>/dev/null; sudo apt install tbench elif yum list available | grep tbench 2>&1 1>/dev/null; sudo yum install tbench else #do existing/install with wget/curl. fi
