How sensors Improve Pump Performance? Sensors to detect Gas, chemical, temperature, pressure levels and more can prevent impeller damage, wear and tear and accurately detect actual cause of damage. With various types of sensors for specific purposes, it is possible to make pumps perform for longer than expected duration. Read on to know more about how various sensors can improve performance.

"Page Speed, the Web Performance Tool Now also an Apache module! Page Speed is an open-source project started at Google to help developers optimize their web pages by applying web performance best practices. Page Speed started as an open-source Firefox/Firebug add-on and is now deployed in third-party products such as Webpagetest.org, Show Slow and Google Webmaster Tools. "

New Jersey stand-up comic Randall Redd was full of cheesy lines in his recent performance. The comedian proposed to his girlfriend during the show with the most inappropriate compliment "Your parents should have named you Gillette because you're the best a man can get.

According to Yahoo!'s Exceptional Performance Team, 40% to 60% of Yahoo!'s users have an empty cache experience and about 20% of all page views are done with an empty cache (see this article by Tenni Theurer on the YUIBlog for more information on browser cache usage). This fact outlines the importance of keeping web pages as lightweight as possible. Improving the engineering design of a page or a web application usually yields the biggest savings and that should always be a primary strategy. With the right design in place, there are many secondary strategies for improving performance such as minification of the code, HTTP compression, using CSS sprites, etc. In terms of code minification, the most widely used tools to minify JavaScript code are Douglas Crockford's JSMIN, the Dojo compressor and Dean Edwards' Packer. Each of these tools, however, has drawbacks. JSMIN, for example, does not yield optimal savings (due to its simple algorithm, it must leave many line feed characters in the code in order not to introduce any new bugs). The goal of JavaScript and CSS minification is always to preserve the operational qualities of the code while reducing its overall byte footprint (both in raw terms and after gzipping, as most JavaScript and CSS served from production web servers is gzipped as part of the HTTP protocol). The YUI Compressor is JavaScript minifier designed to be 100% safe and yield a higher compression ratio than most other tools. Tests on the YUI Library have shown savings of over 20% compared to JSMin (becoming 10% after HTTP compression). Starting with version 2.0, the YUI Compressor is also able to compress CSS files by using a port of Isaac Schlueter's regular-expression-based CSS minifier.

Due to browsers' prohibition on cross domain XMLHTTP calls, all AJAX websites must have a server side proxy to fetch content from external domains like Flickr or Digg. From the client-side JavaScript code, an XMLHTTP call goes to the server-side proxy hosted on the same domain, and then the proxy downloads the content from the external server and sends back to the browser. In general, all AJAX websites on the Internet that are showing content from external domains are following this proxy approach, except for some rare ones who are using JSONP. Such a proxy gets a very large number of hits when a lot of components on the website are downloading content from external domains. So, it becomes a scalability issue when the proxy starts getting millions of hits. Moreover, a web page's overall load performance largely depends on the performance of the proxy as it delivers content to the page. In this article, we will take a look at how we can take a conventional AJAX Proxy and make it faster, asynchronous, continuously stream content, and thus make it more scalable.

Wasting server resources can impact the performance of Ajax applications, resulting in excessive HTTP requests, high memory consumption, and the need for an unusual amount of polling to make applications work. Regular developerWorks author Judith Myerson suggests some open source tools and Firefox add-ons you can use to improve or solve problems with your Ajax applications.

Changing the zoom level, minimum font size, applying a fit-to-width algorithm, or making other changes may alter the rendition of the test page without this constituting a failure in compliance. The Acid3 test measures some performance characteristics. The test does not attempt to make any comparisons or judgments as to the performance of any hardware used, and should not be used as a hardware benchmark. If the test is run on a slow computer or device, it may run slowly or not smoothly and this does not imply non-conformance.

Born and raised in Toronto, Ontario to Trinidadian parents, Nobel began writing music early, at the age of 14, then performing studio recordings at 17. Nobel tributes several genres as an influence; as is evident in her performances which encompass various genres normally regarded as incompatible.

Performance of the User Interface of websites in browsers (multiple results)

External JavaScript files block downloads and hurt your page performance, but there is an easy way to work around this problem: use dynamic scripts tags and load scripts in parallel, improving the page loading speed and the user experience.

Response times, availability, and stability are vital factors to bear in mind when creating and maintaining a web application. If you're concerned about your web pages' speed or want to make sure you're in tip-top shape before starting or launching a project, here's a few useful, free tools to help you create and sustain high-performance web applications. I've tried to include a wide variety of tools that are easy to use, and have tried to keep them as OS and technology-independent as possible so that everyone can find a tool or two.
