MariaDBBench Methodology: Official InnoDB Buffer Pool, Redo Log & Connection RAM Math

MariaDBBench derives every 50-server.cnf parameter from published MariaDB 11.4 LTS & MySQL 8.4 LTS storage-engine formulas and public vendor pricing retrieved 2026-11-12.

Engine Reference: MariaDB 11.4 & MySQL 8.4 Docs
Chunk Alignment: 128 MB Multiples
Peak RSS Guard: <= 92% Physical Host RAM
Vendor Rate Snapshot: 2026-11-12

1. MariaDBBench Host RAM Pool Ratios (70% Dedicated vs 45% Co-Located LAMP)

NominalPoolMB = round_128MB( HostRAM_GB × PoolRatio × 1024 )
ControlBlockOverheadGB = NominalPoolGB × 0.06

Per official MariaDB Server and MySQL InnoDB memory allocation documentation, setting innodb_buffer_pool_size to 70% of physical RAM on a Dedicated DB node reserves essential headroom for 16 KB page descriptors (~6% control-block overhead), redo/binlog buffers, OS kernel structures, and mariabackup streams. On Co-Located LAMP/LEMP servers running Nginx/LiteSpeed, PHP-FPM workers, and Redis alongside mariadbd, MariaDBBench caps innodb_buffer_pool_size strictly at 45% of host RAM to prevent Linux OOM-Killer termination.

2. MariaDBBench Logarithmic Active Working-Set & Redo Checkpoint Sizing

ActiveHotSetGB = DatasetGB × clamp( HotRatioBase × (1.10 − 0.27 × log10(DatasetGB)), 0.34, 0.92 )
RedoLogMB = snapLadder( NominalPoolMB × 0.22 × (0.75 + WriteFraction × 1.45), 512M..16G )

Compact OLTP schemas keep most B+Tree pages hot in memory, whereas multi-hundred-gigabyte databases accumulate cold historical rows while internal B+Tree non-leaf branches stay active. Simultaneously, our generator sizes innodb_log_file_size (MariaDB 11.4 unified redo log) and comments innodb_redo_log_capacity (MySQL 8.4 LTS) between 512M and 16G to prevent synchronous checkpoint stalls under write bursts.

3. MariaDBBench Per-Connection Arena Budget & Symmetric Temp Table Spill Guards

ThreadPeakGB = ( max_connections × (sort_buffer + join_buffer + 1.5MB) + ceil(0.12 × max_connections) × tmp_table_size ) / 1024
EffectiveInMemoryTempCap = MIN( tmp_table_size, max_heap_table_size )

Because MariaDB allocates sort_buffer_size, join_buffer_size, and per-query temporary tables dynamically across active threads, MariaDBBench models worst-case concurrent RSS against 92% of physical RAM and always sets tmp_table_size equal to max_heap_table_size alongside thread_handling = pool-of-threads.
