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
