I tried using ZRAM writeback to optimise RAM usage. Compared to standard ZRAM, it can write back inactive ZRAM pages to the hard disk, freeing up the memory that ZRAM would otherwise occupy. This allows us to expand our available RAM while retaining the high swap speeds provided by ZRAM.
Recently I encountered a classic performance issue in MSSQL called plan regression. In this post, I will share my experience of troubleshooting and solving this problem.
