96918
To check performance .. You can check each page loading time, database monitoing and web server performance.

Opera and Netscape also can do the simultaneously loading. Speed is much faster than IE\n\nd10v01b

This is really wide question. Especially which Database server are you using? Depending on all of them, you will have different techniques to do it. For example, I will answer for SQL Server since I work on them. Out of box, SQL Server provides Database Tuning Adviser (SQL 2005) and Index tuning wizard (SQL 2000) to help you tune indexes to make your stored procs or queries run faster. Some times you could rewrite the queries in different way, break them up etc to make them run faster. Few of the things I would list out here are web casts and articles which may help you get started on this. And you probably should buy some DBA handbook or tuning guides which may show you little tricks etc as well. The links I am putting here are largely for sQL Server again. You could find info for other database servers on their respective sites OR some other expert sites.

Processor speed and available memory are *equally* important, as it wouldn't make sense to have a fast thinking 'brain' (processor) without a sufficient 'highway' (RAM) to funnel all of the incoming and outgoing data streams.\n\nThe new accepted minimal standards these days for being able to run all of the media rich program content on the web is to have at least a 1.5 GHz to 2.5 GHz processor with a minimum of 512 Kb to 1024 Kb RAM.

Just looked at their website.This is an 'all-in-one ' package which may suit a greenfield development but if you are having to integrate with other middleware? Tomcat/JBOSS/Websphere/Microsoft MTS/.NET?.It's all very well using grids,parallelism and clustering , but you still have the page-lock or contention problem , i.e. what if 2 processes are after the same part of the DB? They have a Caching Edition , but this only postpones the problem . If you have less than 100 TPS then your usually OK with a single instance of MySQL. Any more than that and you start haibg to think a bit. ( take a look at the Oracle performance tuning sites , lots theree about disk / cache / processor configuring).

Less now than ever before.  The key to maximum performance now is matching the CPU, Memory, Bus, Hard drive and Video speeds.  Increasing any one of these may have little effect if the other four are "slow" in comparison.

If you have an old version, memory leaks can make it slower as you let it sit.  Also if you have lots of extentions, some of them may slow down.  Try removing some, or  upgrading Firefox.

There's a good head to head reported on zdnet:\n\nhttp://reviews.zdnet.co.uk/software/productivity/0,1000001108,39284445,00.htm\n\nSeems FF wins pretty much all the categories.

Use firefox or opera for browsing. extensions for either can make life much easier and save time. session saving, integrated rss feeds, and keyboard shortcuts are the best.

too many requests sent to the website than it is designed to handle or some spurious programs may cause website freeze

For client side application programs the hot stuff is anything .NET, preferably c# and even vc++.net is doing well. Java is really taking off too.\n\nFor server side web programming... PHP hands down is hot. Paired up with MySQL, that technology is really dominating. Perl is there, but slowly dying by the wayside.\n\nFor web development, AJAX and straight XML with a sprinkle of DHTML. Its the foundation of the Web 2.0 movement.\n\nBelieve me, I have my hands in all three of these categories and I often can't keep up with all the work people want to throw at me. I pretty much can command my own perks and salary because of it.\n\nHope I helped you out with this.

not very often only whenyou absolutely need to... try running a defrag to improve performance.

URNDWAY IS Way Wrong. It is a Windows XP thing.\n\nControl Panel > \nPerformance and Maintenance > \nSystem. \n\nChoose the Advanced tab, and click the Settings button under Performance. \n\nDEP settings are on the Data Execution Prevention tab\n\nCHOOSE WISELY
