Gauge binaries are getting bigger #310

Closed mahendrakariya closed 8 years ago

mahendrakariya commented 8 years ago

Gauge binaries are growing big. It used to be around 4-5 MB earlier.

The 64 bit binary generated for the HEAD of this repo is around 15 MB.

Did some more analysis. Here's the list of top 10 objects (by size) in the Gauge binary for darwin/amd64. This adds up to ~8.069 MB.

Name Size (in MB)
runtime.rodata 2.286576
type.* 2.286576
runtime.pclntab 1.934885
go.string.* 1.104472
go.func.* 0.18722
runtime.trace 0.065688
runtime.typelink 0.061888

Tried creating an executable for darwin/amd64 for a hello world program written in Go. The binary size is 2.3 MB. Given this, I really doubt if we will be able to reduce the binary size to <5MB, what it used to be earlier. But will continue to analyze to see what can be done.

Can this be due to optimizations added in Golang? Is there any change in binary size for Gauge if it is compiled with golang 1.5.x vs golang 1.6.x?

mahendrakariya commented 8 years ago

There is no significant change in the binary size between different Go versions. On Mar 17, 2016 1:19 AM, "Kaustav Das Modak" notifications@github.com wrote:

Closing this. Will revisit if there is any further bloat.
