 [rubygems/rubygems] Fewer allocations in gem installation 2023-12-11T23:14:58+00:00 Samuel Giddins segiddins@segiddins.me 2023-09-19T01:51:15+00:00 505715ddf17e004d184c0b71afb40a31e2e8c98e For now, on a small rails app I have hanging around: ``` ==> memprof.after.txt <== Total allocated: 872.51 MB (465330 objects) Total retained: 40.48 kB (326 objects) ==> memprof.before.txt <== Total allocated: 890.79 MB (1494026 objects) Total retained: 40.40 kB (328 objects) ``` Not a huge difference in memory usage, but it's a drastic improvement in total number of allocations. Additionally, this will pay huge dividends once https://github.com/ruby/zlib/pull/61 is merged, as it will allow us to completely avoid allocations in the repeated calls to readpartial, which currently accounts for most of the memory usage shown above. https://github.com/rubygems/rubygems/commit/f78d45d927 
For now, on a small rails app I have hanging around:

```
==> memprof.after.txt <==
Total allocated: 872.51 MB (465330 objects)
Total retained:  40.48 kB (326 objects)

==> memprof.before.txt <==
Total allocated: 890.79 MB (1494026 objects)
Total retained:  40.40 kB (328 objects)
```

Not a huge difference in memory usage, but it's a drastic improvement
in total number of allocations.

Additionally, this will pay huge dividends once
https://github.com/ruby/zlib/pull/61 is merged, as it will allow us to
completely avoid allocations in the repeated calls to readpartial,
which currently accounts for most of the memory usage shown above.

String#unpack("C*") is equivalent to String#bytes and Array#inject {|a,b| a + b } is equivalent to Array#sum.
This is a minor enhancement in terms of speed and readability.
