MariaDBBench Split-Pane 50-server.cnf Generator & InnoDB Buffer Pool Studio
At MariaDBBench, we calculate deterministic innodb_buffer_pool_size allocations (70% Dedicated DB rule vs 45% Co-Located LAMP rule), innodb_log_file_size redo horizons, and per-connection OOM memory ceilings directly from official MariaDB 11.4 LTS and MySQL 8.4 LTS documentation.
MariaDBBench Official Directive Reference for 50-server.cnf & InnoDB Memory Sizing
We document the exact storage-engine mechanics behind each generated directive using official MariaDB 11.4 LTS and MySQL 8.4 LTS reference manuals rather than obsolete query_cache folklore.
innodb_buffer_pool_size-
In our MariaDBBench memory engine, we align innodb_buffer_pool_size to 128 MB multiples matching innodb_buffer_pool_chunk_size in MariaDB 11.4 LTS and MySQL 8.4 LTS. On a Dedicated DB server, allocating 70% of physical RAM pins hot B+Tree pages in DDR5 while reserving 30% for 16 KB page-descriptor control blocks (~6% extra RSS), lock hash tables, OS kernel structures, and mariabackup streams.
Co-located PHP-FPM hosts cap strictly at 45% RAM.
innodb_log_file_size-
MariaDB 11.4 LTS manages redo durability through a single unified ib_logfile0 sized via innodb_log_file_size, whereas MySQL 8.4 LTS uses innodb_redo_log_capacity. Our configurator scales redo capacity between 512M and 16G from buffer pool size and write ratio so background page cleaners absorb burst commits without triggering synchronous furious flushing stalls.
Undersized redo logs stall transactional UPDATE bursts.
innodb_flush_log_at_trx_commit-
Setting innodb_flush_log_at_trx_commit = 1 enforces strict ACID compliance by flushing the redo log buffer to non-volatile NVMe media on every COMMIT via group commit—mandatory for Magento 2 checkouts, WooCommerce HPOS orders, and Laravel financial ledgers. Setting = 2 writes to the Linux OS cache per commit and flushes once per second for XenForo forums or analytics replicas.
Keep = 1 for every payment and inventory schema.
innodb_flush_method = O_DIRECT-
Enabling innodb_flush_method = O_DIRECT instructs MariaDB to bypass the Linux filesystem page cache when reading and writing .ibd tablespace files on local NVMe storage. Eliminating double buffering frees gigabytes of host RAM for InnoDB pages while preventing kernel dirty-page writeback spikes.
Always keep innodb_doublewrite = ON alongside O_DIRECT.
max_connections & thread_handling-
Because sort_buffer_size, join_buffer_size, and per-query temporary tables allocate per active session, inflating max_connections without bounding per-thread buffers is the primary cause of mysqld OOM crashes. MariaDBBench enables native MariaDB 11.4 thread_handling = pool-of-threads with thread_pool_size matched to host vCPU cores.
Bound max_connections or multiplex via ProxySQL.
tmp_table_size & max_heap_table_size-
Official MariaDB Server and MySQL documentation specify that the effective ceiling for an explicit or implicit in-memory temporary table is MIN(tmp_table_size, max_heap_table_size). We output symmetric 64M to 256M values for both directives so complex GROUP BY and WooCommerce attribute filters do not prematurely spill onto disk.
Mismatched temp caps silently force Aria disk spills.

MariaDBBench Frequently Asked Questions on MariaDB 11.4 & 50-server.cnf Sizing
Why does MariaDBBench enforce 70% RAM on Dedicated DB hosts vs 45% on Co-Located LAMP stacks?
Per official MariaDB 11.4 LTS and MySQL InnoDB memory documentation, nominal innodb_buffer_pool_size excludes ~6% page-descriptor control blocks, redo log buffers, and dynamic per-thread sort/join/temp buffers. Dedicated DB nodes safely sustain a 70% pool ceiling, whereas co-located Nginx/LiteSpeed + PHP-FPM + Redis hosts must cap InnoDB at 45% RAM to prevent Linux OOM-Killer termination.
Does the MariaDBBench 50-server.cnf output work on both MariaDB 11.4 LTS and MySQL 8.4 LTS?
Yes. MariaDBBench outputs native MariaDB 11.4 LTS directives—including unified lock-free buffer pools, single-file innodb_log_file_size, and thread_handling = pool-of-threads—while commenting exact MySQL 8.4 LTS equivalents such as innodb_redo_log_capacity and innodb_buffer_pool_instances right inline.
When does the MariaDBBench decision tree recommend splitting PHP-FPM and MariaDB onto separate servers?
Our deterministic decision tree flags topology isolation whenever a co-located LAMP/LEMP workload reaches >= 45 GB of InnoDB tablespaces or >= 350 max_connections, where the 45% RAM ceiling and CPU L3 cache contention degrade B+Tree page residency.
How does MariaDBBench source and verify the VPS and VDS pricing tiers in the RAM ledger?
We cite official public pricing pages from ChemiCloud, Hostinger, InterServer, Vultr, and UltaHost retrieved on 2026-11-12. Because introductory discounts and multi-year renewal rates change periodically, we advise verifying current billing terms directly on each vendor checkout page before deploying.
