## x-ecutioner

This is just a script plus some code that will generate a compressed version of a linux ELF executable, - so your Go linux binary could be smaller!

Requirements:

	go > 1.13

	go-binddata

	

Usage:

	./generate.sh BINARYFILE

	

This wil generate a new file, called *BINARYFILE_mem*, that hopefully will be smaller than the original.

>For small binaries this doesn't work, it will actually generate a bigger binary! So try and see.

The new binary will be slightly slower at start. See below.

memrun.go is originally from here https://github.com/guitmz/memrun, modified for this usage.

#### My tests

**Compression:**

	13197468 binary1

	 8368128 binary1_mem

	

	(from ~13mb to ~8mb)

	

	27190864 binary2

	18780160 binary2_mem

	

	(from ~27mb to ~18mb)

	

**Execution time:**

	time ./binary1

	...

	real    0m0.014s

	user    0m0.012s

	sys     0m0.004s

and the compressed one:

	time ./binary1_mem 

	...

	real    0m0.348s

	user    0m0.327s

	sys     0m0.047s

	

another example:

	time ./binary2

	...

	real    0m0.007s

	user    0m0.000s

	sys     0m0.008s

	

and the compressed version:

	time ./binary2_mem 

	...

	real    0m0.630s

	user    0m0.600s

	sys     0m0.064s
