OpenLiteSpeed benchmark discussion

Seems other thread's dominant discussion is over Litespeed Enterprise TOS So starting this thread for folks to post their own OpenLiteSpeed benchmarks and results from their own testing :)

    Only started testing but looks good so far, stock out of box Centmin Mod Nginx v1.4.1 vs stock of out box OpenLiteSpeed 1.0 for static files. Of course concurrency levels are low so not enough to differentiate between the 2. Only changes made is set Nginx worker processes to 4 and same for OpenLiteSpeed.

    Seems OpenLiteSpeed wins on Longest Transaction time being faster.

    Note default Centmin Mod Nginx also has open_file_cache enabled as well.

    Siege Benchmark v3.0 Tested against

    • static hello.txt text file with 'hello world' text
    • static nginx-logo.png default logo included with Nginx installs

    • Nginx on port 80

    • OpenLiteSpeed on port 8088

    Nginx hello.txt

    OpenLiteSpeed hello.txt

    Server Configuration:

    VirtualBox - CentOS 6.4 64bit
    Xeon W3540 @3.2Ghz allocated 4 cpu threads
    1280MB memory
    20GB disk on 1TB Western Digital Black Caviar


    Centmin Mod v1.2.3-eva2000.01 Beta
    Nginx 1.4.1 with ngx_pagespeed support turned off
    PHP 5.2.4 PHP-FPM + APC Cache 3.1.13 + Memcache 3.07 + Memcached 2.1.0 + Libmemcached 1.0.16
    MariaDB 5.2.14 MySQL

    OpenLiteSpeed 1.0
    PHP 5.3.24 LSAPI + APC Cache 3.1.13 + Memcache 3.07 + Memcached 2.1.0 + Libmemcached 1.0.16

    Siege Benchmark 3.0 settings

    - Cache validation disabled (default)
    - Concurrency levels tested: 50, 100, 150, 200, 250
    - Reps: 10
    - Delay: 5 seconds
    - Siege benchmark mode: bench

    Actually the other thread is now about minorities, murder, and religion. Thanks for sharing your benchmarks like a normal person does when talking about a web server. I'm quite interested in learning what the benefits are of LiteSpeed without so many of the key features.

    Did you expect anything better?

    Yeah I'm just interested in performance of OpenLiteSpeed particularly in comparison to Nginx. I chose lowendtalk for the discussion as on average you folks would have a higher technical expertise for this compared to other forums as well. That and alot of pro-Nginx folks :)

    Let's see main features missing from OpenLiteSpeed vs Litespeed Enterprise

    • hosting control panel compatibility
    • .htaccess file compatibility
    • mod_security compatibility
    • page caching

    Hosting control panels - how many Nginx users even use a control panel ?

    .htaccess file compatibility - it's only the file not supported, Apache rewrite syntax is fully supported but seems they moved that up into vhost admin console configuration in rewrite and context tabs. Haven't played with that aspect of OpenLiteSpeed yet but at least it uses Apache rewrite syntax !

    mod_security, how many folks use mod_security ? for Nginx ?

    page caching - I assume this means Litespeed Enterprises' inbuilt Litespeed Cache. That would probably be the feature I'd miss the most. I wrote about Litespeed Cache vs Varnish Cache 2+ yrs ago on my blog Litespeed Cache performed as good if not better than Varnish cache for dynamic PHP caching.

    But OpenLiteSpeed still retains Litespeed Enterprises inbuilt small static file and MMAP cache support from the admin console screenshot (see below). So static file cache/performance is right up there with Varnish Cache for static files (in theory).

    @eva2000 I really noobs about OpenLiteSpeed. Could you write some tutorial on installing wordpress.

  • neqsteneqste Member

    I see only one problem with LiteSpeed webserver.
    It's enterprise edition, what cost money for get all features.
    Nginx give a lot features for free from box. Same as like apache.

    I hope, Nginx and LiteSpeed will be good concurents, and they remove monopoly from Apache by their features / quality / speed / resource usage.

  • it's free? Oh more spam site / autoblog.

  • NoxterNoxter Member

    Thank you for taking the time to post your results eva2000. Appreciate it!

  • vanarpvanarp Member

    @eva2000 One of the main reasons I shifted from Apache to Nginx on my LEBs was due to high memory consumption. Interested in knowing how does OpenLiteSpeed compare with Nginx in terms of memory consumption (right from zero concurrency)?

  • eva2000eva2000 Member

    @Noerman, if i have time I may eventually - seems LitespeedTech are planning guides for common web scripts too so might keep an eye out for that on their web site, blog and google group

    @Noxter you're welcome

    @vanarp, early tests show memory usage very close between the 2 of course depends on specific Nginx or OpenLiteSpeed settings used. But for Centmin Mod based Nginx vs OpenLiteSpeed very close. Siege benchmarks show Nginx peak 150-210MB memory usage vs OpenLiteSpeed 150-180MB memory peak and idle well

  • I've been meaning to do a simple benchmark comparison - I'm trying to think of the best environment to do it in with - maybe AWS? I have DO credit but I don't trust their VMs

  • eva2000eva2000 Member

    Only real problem is you need to test at very high concurrency based loads to see Litespeed (assume OpenLiteSpeed) benefits over Nginx. So target test server needs to be able to handle it. As such I'm moving my test from virtualbox to a more beefier server(s) eventually :)

  • vanarpvanarp Member

    @eva2000 And also testing concurrency on a typical WordPress site will give much better idea since most sites would be running WP anyway IMHO.

  • Thanks @eva2000.
    I may have found an apache replacement :)

    heads up official quick install guides for wordpress, joomla and magento are up on their official site

    You are awesome! I am excited to try it for WP over the weekend.
