OpenLiteSpeed vs Apache: Raw Performance Comparison
| Metric | OpenLiteSpeed | Apache |
|---|---|---|
| Response Time | Quick responses, under 1.5 seconds for page loads. | Slower, around 1.5 seconds with optimization, but can be higher without tuning. |
| Throughput (Requests/Sec) | Handles high requests per second. Benchmarks show 167,752 RPS for small static files and 7,765 RPS in general tests (2025). | Lower throughput. 5,704 RPS for small static files over HTTP/2 and 6,384 RPS in general tests (2025). |
| Resource Usage (CPU & RAM) | Low resource consumption, using 60% CPU and 700 MB RAM. | Higher usage, with 78% CPU and 850 MB RAM. Less suitable for low-resource environments. |
| Static File Performance | Outperforms by up to 29X for small static files over HTTP/2. | Much slower, managing only 5,704 RPS for the same static file test. |
| Large File Transfer Rate | High efficiency, with a transfer rate of 122.78 MB/sec for a 10MB file. | Lower rate at 103.83 MB/sec for the same file size, indicating less efficiency. |
| Latency (High Concurrency) | Better under pressure, with 272.3 ms latency at high concurrency levels. | Higher latency, reaching 312.5 ms under similar high concurrency conditions. |
OpenLiteSpeed vs Apache: Caching Capabilities Comparison
1. OpenLiteSpeed
-
LSCache is a high-performance, full-page caching module integrated into OpenLiteSpeed. It operates within the server, eliminating the need for a reverse proxy layer. This enhances efficiency for both static and dynamic content.
-
OpenLiteSpeed supports both public and private caching. Public cache serves content to all users, while private cache is for logged-in users. It ensures personalized content gets cached.
-
LSCache allows caching of URIs with query strings (qsCache). It can also serve cached responses for requests with cookies (reqCookieCache).
-
OpenLiteSpeed offers granular control over caching. For instance, specific URLs get cached for defined periods (e.g., 120 seconds for PHP files). Certain paths get excluded from caching.
-
Cache data storage is customizable via the storagePath setting. It supports paths and variables like $VH_ROOT for virtual host-specific caches. This allows efficient organization of cache data across sites on the same server.
2. Apache
-
Apache’s primary caching mechanism is by the mod_cache module. It uses HTTP-aware caching for accessed content. It acts as a URL mapping module, serving cached content if unexpired.
-
The mod_cache_disk module stores cached content on disk. It is ideal for larger caches where memory is a constraint. It uses a hashed URL structure for storage. It comes with configurable parameters like
-
CacheRoot
-
CacheDirLevels
-
CacheDirLength.
-
-
This method is persistent across server restarts, ensuring reliability.
-
For faster access, mod_mem_cache stores content in RAM. It is suitable for smaller, high-demand caches. Key directives like MCacheSize and MCacheMaxObjectCount define cache limits. It consumes memory and isn’t persistent across restarts.
-
Apache also supports memory-based caching via mod_socache_shmcb. It uses shared memory for storage. It is configurable with directives like CacheSocacheMaxSize and CacheDefaultExpire.
-
Apache enhances client-side performance through browser caching. It instructs clients to store static resources using mod_expires and mod_headers. This reduces repeated downloads.
-
Apache can use proxy caching to store content on intermediary servers. It reduces latency and origin server load. This gets executed with external tools like Varnish or through Apache’s mod_proxy.
