I did experimental change and rebase. |
Using LDB_NOSYNC option significantly improves the cache performance. However, it still uses the cache recovery area, so the cache is still resilient when using this option even if SSSD is forcibly terminated. There is small chance that cache become inconsistent, when computer is unexpectedly switched off while transaction is being written to cache file. :config: New option 'cache_in_memory_transaction' to use fast transaction and improve cache performance.
This patch sets default for in-memory transaction to true!

Hi Tomas, can you give us also some numbers? As a tip, you can use https://github.com/sharkdp/hyperfine to do the measuring. |
Hi I have another task to create some performance comparison pipeline. I will share results once I run it. |
