  • Event-Driven Architecture - LiteSpeed Technologies Inc
    that pop up new requests coming in and new dynamic responses ready to go out LiteSpeed Web Server concerns itself not with creating new processes to handle every aspect of every connection but with reacting to events that occur For static content like images CSS html the advantage is obvious instead of consuming the overhead required for a new process for each request LSWS s one process just handles the requests as they come in This is much faster and consumes much less CPU and memory than Apache For web applications like PHP and database processes like My SQL the interaction is a little more complex LSWS fields requests and sends them along to external processes that create responses LSWS does not wait around for these dynamic responses but instead gets to work fielding more requests requests for static content which it retrieves and requests for dynamic content which it forwards on while the initial requests are getting processed When a response is ready LSWS gets a callback a new event to react to and knows to send that response back to the requesting client In addition LSAPI LiteSpeed s server API keeps control over the number of processes that get created for web applications reusing processes instead of creating new processes further increasing CPU and memory efficiency Fielding all these requests and responses with one or a few processes is far more CPU and memory efficient than trying to create a separate process for each connection When you get tens of thousands of concurrent connections an event driven server s CPU and memory usage do rise but not exponentially like Apache This also allows for faster content delivery because the server skips the overhead of creating new processes and has more memory left for handling database and external applications

  • HTTP/2 Support - LiteSpeed Technologies Inc
    maintain high compatibility with HTTP 1 1 As such the HTTP semantics have not been changed ensuring backwards compatibility Browsers will also automatically switch from HTTP 1 1 to HTTP 2 if both they and the server support it This switch is both instant and invisible to the user Beneficial to the End User HTTP 2 is proven to have faster page load speeds especially for encrypted HTTPS sites Encryption is stronger with required support for Perfect Forward Secrecy for a more private more secure browsing experience Beneficial to Hosting Service Providers Whether you provide hosting to big companies trying to increase conversion rates or small blogs looking to improve their audience retention there is no better way to accomplish these things than by providing a smoother faster browsing experience HTTP 2 gets content to consumer devices more quickly efficiently and securely than other existing network protocols Thus by combining the improvements brought by HTTP 2 with the speed and efficiency of LiteSpeed Web Server you become a much more attractive hosting option Available Now If you happen to be using the latest versions of popular web browsers such as Google Chrome or Mozilla Firefox you are already set up to take advantage of all the benefits of HTTP 2 enabled web pages Examples of these include web sites powered by Google and all current editions of LiteSpeed Web Server HTTP 2 uses HPACK Header Compression Because of TCP s Slow Start mechanism it is beneficial to send out as few packets as possible to reduce the total number of round trips required when loading a page By compressing the involved message headers what would normally take several round trips can now be done in one This type of compression was used by default in SPDY using GZIP and optionally in HTTPS Since then a security exploit known as CRIME has made GZIP and this type of compression unsecure In response to this HTTP 2 uses HPACK a new header specific compression scheme created by The Working Group that possesses reasonable compression efficiency while still being secure Optional Encryption HTTP 2 uses TLS for encryption but like HTTP 1 1 does not require it Despite this both Mozilla Firefox and Google Chrome have stated that they will only allow HTTP 2 over an encrypted connection These decisions in effect make encryption mandatory facilitating more secure communication on the Web Server Push Server Push is a method of information delivery where a server pushes a resource directly to the client without first receiving a request to do so By doing this the server can attempt to anticipate client requests and pre push them into the client s cache in an effort to avoid the usual request response round trip delay HTTP 2 Server Support If you would like to check a web server site for HTTP 2 support you can do so with the following browser extensions add ons HTTP 2 and SPDY indicator Chrome extension HTTP 2 and SPDY indicator

  • LSWS vs. Reverse Proxies - LiteSpeed Technologies Inc
    panels nginx as a reverse proxy Speeds up static content only Requires additional configurations for compatibility with control panels and web applications Does not increase dynamic content performance Varnish Serves cached pages quickly but requires specialized configuration for individual websites and management of out dated cache Thread based architecture has steep RAM costs Cached copies require extra disk space or RAM while offering less static speed improvement than LSWS or nginx Not recommended for VPSs with tight resources Detailed feature comparison LiteSpeed Web Server nginx as a reverse proxy Varnish Easy to set up Reads your Apache configs so it already knows your settings Install and switch in less than 15 minutes Requires extra and sometimes multiple configurations for each application Requires tailoring to individual sites as well as which pages can be cached and how to deal with stale cache Compatible with Apache sites and control panels out of the box Apache drop in replacement designed to be compatible with all Apache hosting control panels and web applications Most hosting control panels and applications are not designed to be compatible with nginx as a reverse proxy While some plugins exist for use with control panels still needs to be configured for each use case Speeds up all content Replaces all Apache functions streamlining and speeding up both static and dynamic content Only serves static content leaving web applications dynamic content for Apache Cached pages are served quickly though not all pages are suitable for caching and static content improvements may be minimal Scalability Event driven architecture means a minimum of processes cutting RAM usage and load allowing more traffic with less hardware Lightweight though Apache still requires high CPU and RAM overhead to handle all dynamic content Resource intesive Thread based architecture has high RAM overhead Caching requires disk

  • Anti-DDoS Advances - LiteSpeed Technologies Inc
    easily gather data about the number of connections or amount of bandwidth an IP is using This allows the server to efficiently impose limits Thread or processed based applications like Apache have trouble implementing features like this because they need to collect information from their many processes By the time they know which IP to block it s too late Per IP Throttling LiteSpeed Web Server has per IP connection request and bandwidth throttling With these customizable features IPs that make too many connections or requests or ask for too much bandwidth will be blocked stopping attackers before they overrun your server Scalability LiteSpeed Web Server handles much more traffic with far less resources allowing it to survive larger attacks than less scalable solutions This is especially important for very distributed attacks where it is harder to isolate and block each attacker Against such attacks the best defense may be a scalable server SSL Renegotiation Protection SSL renegotiation attacks can tie down a server by repeatedly renegotiating key material in an SSL connection Because generating a key has substantial overhead for a server this can allow smaller machines to take down large servers without enlisting a large network LiteSpeed Web
