Binary Size

All notable changes in program binary size will be documented in this file.

The changes are calculated by comparing the current results with the last version's results. Increase in size is shown with 🔴 and decrease is shown with 🟢.

The programs and their tests are located in /tests/bench.

Note Results documented in this file are autogenerated. Running the tests will update the current results when necessary, manually editing the results should be avoided.

Warning Results may vary depending on Solana version.

[Unreleased]

Solana version: 2.1.0

Program Binary Size -
bench 1,041,928 🔴 +250,920 (31.72%)

Notable changes

  • lang: Use closures for init constraints to reduce the stack usage of try_accounts. Note that the binary size increase is exaggerated for the bench program because it uses unusual number of init constraints. Impact for normal programs will be a lot less severe. (#2939).
  • Upgrade to Solana 2.1.0. This upgrade decreased the binary size ~5% (55,000 bytes) (#3339).

[0.30.1]

Solana version: 1.18.17

Program Binary Size -
bench 791,008 -

Notable changes

[0.30.0]

Solana version: 1.18.8

Program Binary Size -
bench 791,008 🔴 +47,952 (6.45%)

Notable changes

  • Upgrade Solana to 1.18.8 (#2867).

[0.29.0]

Solana version: 1.17.0

Program Binary Size +/-
bench 743,056 🟢 -417,904 (36.00%)

Notable changes

  • Box the anchor_lang::Result error variants (#2600).
  • Change all accounts to have a reference to AccountInfo instead of cloning (#2656).
  • Reduce unnecessary cloning (#2663).

[0.28.0]

Solana version: 1.16.0

Program Binary Size +/-
bench 1,160,960 🔴 +23,272 (2.05%)

Notable changes

  • Upgrading Solana to 1.16. The difference in binary size between 0.27.0 and 0.28.0 is the direct result of upgrading Solana version(both build tools and crates) (#2512).

[0.27.0]

Solana version: 1.14.16

Program Binary Size +/-
