Optimize Testcase Execution Time on go Binaries

[Arker123]

Currently, executing each testcase on Kubernetes binaries is proving to be a time-consuming process, with an approximate duration of 1 hour.

On a first glance, these are slower:

• (".rdata", ".data") extraction
• longstring64 and longstring64_2 extraction (.text section)

[mr-tz]

some profiler results, pefile functions may be slow and we could replace them

Can this be closed?

[Arker123]

Yeah, sure! The current execution time for the test cases is already pretty low, so I think we can go ahead and close the issue. Thank you for your guidance and support throughout the optimization process. 😄
