See also: Database Query Optimization. Consider using a database connection pool like PdoConnectionPool.
Finally, consider monitoring resource usage during benchmarking with `vmstat` and `iostat` to identify specific bottlenecks. For example, high CPU usage suggests a CPU bottleneck, while high disk I/O indicates a disk bottleneck. See also: Server Security.

Benchmarking Your MediaWiki Server
This article provides a guide to benchmarking your MediaWiki 1.40 server to understand its performance characteristics and identify potential bottlenecks. Regular benchmarking is crucial for maintaining a responsive wiki, especially as content and user base grow. We will cover various tools and metrics useful for assessing server performance. This guide assumes a basic understanding of server administration and command-line tools.
Why Benchmark?
Benchmarking helps you:
- Identify Bottlenecks: Determine if performance limitations stem from the CPU, memory, disk I/O, or database.
- Plan for Scalability: Understand how your server will perform under increasing load, allowing you to proactively upgrade hardware or optimize configurations.
- Measure the Impact of Changes: Evaluate the effectiveness of software updates, configuration tweaks, or caching strategies.
- Establish Baselines: Create a performance baseline to track degradation and identify issues before they impact users. See also: Server Performance Monitoring.
Tools for Benchmarking
Several tools can be used to benchmark a MediaWiki server. Here are some common options:
- ApacheBench (ab): A command-line tool for measuring the performance of HTTP web servers. Useful for simulating user load. See: Apache HTTP Server.
- wrk: A modern HTTP benchmarking tool designed for high-load testing. Often faster and more efficient than `ab`.
- MySQL Benchmark Tools: Tools like `mysqlslap` can benchmark the MySQL/MariaDB database server. See: Database Administration.
- vmstat: A system monitoring tool that reports virtual memory statistics, processes, CPU activity, and I/O.
- iostat: Reports CPU statistics and input/output statistics for devices and partitions.
- top/htop: Real-time process monitoring tools. See: Server Processes.
- PHPBench: A dedicated benchmarking tool for PHP code, useful for testing specific MediaWiki extensions or customizations. See: PHP Configuration.
Benchmarking the Web Server (Apache/Nginx)
We'll use `ab` to benchmark the web server's ability to handle requests. First, install `ab` if it isn’t already available. (On Debian/Ubuntu: `sudo apt-get install apache2-utils`).
A basic `ab` command looks like this:
ab -n 1000 -c 10 http://yourmediawiki.example.com/* `-n 1000`: Sends 1000 requests. * `-c 10`: Uses 10 concurrent requests. Adjust this based on your server's resources. Start low and increase carefully. * `http://yourmediawiki.example.com/`: The URL of your MediaWiki installation. Analyze the output of `ab`. Key metrics include: * Requests per second: Indicates the server's throughput. * Time per request: Average time to serve a request. * Transfer rate: Data transferred per second. Here's an example of how to interpret some results:
| Metric | Value | Interpretation |
|---|---|---|
| Requests per second | 150 | The server can handle 150 requests per second. |
| Time per request (ms) | 66.67 | Each request takes approximately 67 milliseconds to process. |
| Transfer rate (KB/sec) | 1200 | Approximately 1.2 MB of data is transferred per second. |
Benchmarking the Database Server (MySQL/MariaDB)
Database performance is critical for MediaWiki. `mysqlslap` is a useful tool.mysqlslap --auto-generate-test --number-of-queries=1000 --concurrency=10 --engine=innodb --create-schema=mediawiki* `--auto-generate-test`: Automatically generates test queries. * `--number-of-queries=1000`: Runs 1000 queries. * `--concurrency=10`: Uses 10 concurrent connections. * `--engine=innodb`: Specifies the InnoDB storage engine. * `--create-schema=mediawiki`: Creates a test schema named 'mediawiki'. WARNING: This will create a database. Use a test instance! Key metrics to observe from `mysqlslap` include: * Queries per second: Database throughput. * Average latency: Average time to execute a query. * Minimum/Maximum latency: Range of query execution times. Here's an example:
| Metric | Value | Interpretation |
|---|---|---|
| Queries per second | 80 | The database can process 80 queries per second. |
| Average latency (ms) | 12.5 | Queries take an average of 12.5 milliseconds to execute. |
| Minimum latency (ms) | 1.0 | Fastest query execution took 1 millisecond. |
Benchmarking MediaWiki Specific Operations
Beyond the web and database servers, it's useful to benchmark specific MediaWiki operations, such as page viewing and editing. You can use `ab` or `wrk` to simulate these: * Page Viewing: Benchmark accessing a typical article page. * Page Editing: Benchmark submitting a small edit to a page. (Requires authentication, so you'll need to include cookies in your `ab` or `wrk` requests). * Search: Benchmark performing a search query. Here's a table summarizing typical server specifications for different wiki sizes:| Wiki Size | CPU | Memory (RAM) | Disk Space | Database |
|---|---|---|---|---|
| Small (Under 1000 pages) | 2 cores | 4 GB | 50 GB | MySQL/MariaDB (Small Instance) |
| Medium (10,000 - 50,000 pages) | 4-8 cores | 8-16 GB | 250 GB | MySQL/MariaDB (Medium Instance) |
| Large (Over 50,000 pages) | 8+ cores | 32+ GB | 500 GB+ | MySQL/MariaDB (Large Instance) / Database Cluster |
