Browser performance appears to be running slow when using Internet Explorer. Time waiting between pages is 5-15 seconds between pages. When performance appears to be running slow and other web sites appear to be running fine, first check the www.projectinsight.net website. If that performs adequately then the problem may reside with the browser settings.
Follow these steps to try to isolate the problem and let support know which one is causing the issue.
There are known issues with certain settings in Internet Explorer which cause JavaScript to perform very slowly on the client. Other applications, such as anti-virus software, pop-up blockers, and other add-ons that examine your browser activity can interfere with Project Insight. NOTE: McAfee Managed Virus Scan and McAfee Virus Scan software specifically has a feature called "Script Scan" which causes IE performance to be significantly degraded! Contact support for the McAfee IE performance FAQ info.
Test Slow Performance Steps. The following procedures are for testing only. Though sometimes requiring a temporary change to a configuration, these procedures should be approached with caution and do not represent recommendations for permanent configuration changes. Changes to security settings, even temporary changes, should always be performed by those authorized personnel within your organization responsible for systems security.
Before you start you need to document your current configuration and document any changes you have made. Open your task manager so you can view the CPU usage by right mouse clicking on the windows toolbar at the bottom of your screen and selecting "Task Manager."
1. Empty cache
Reason: Project Insight makes heavy use of Javascript, which can have performance and reliability issues when the browser cache is nearing capacity. Although the browsers are supposed to automatically purge a full cache, they do not always do so properly. Instructions for emptying cache can be located in the help for your particular browser, or you can reference the FAQ for "Browser Cache Full" in the Project Insight online help.
2. Adjust your temporary internet files settings
Open IE, go to Tools -> Internet Options -> General Tab. Under the subsection "Browsing History" select the button "Settings". In the settings view the selection for "Check for newer versions of stored pages." Set it to "Automatically" the default.
Reason: Often times IE plug-ins, anti-virus software, or popup blockers scan a page that IE downloads and checks the JavaScript within the page for problems. The operation the third party software products and plug-ins can be CPU intensive and time consuming. If your browser is set to "Every visit to the page" then these products will be invoked each time you click on any link within IE. The slow performance is caused by the client computer processing too much. If you are able to identify which third party application is interfering with Internet Explorer you can reset your settings. As long as nothing is interfering with your browser you can have your settings to "Every visit to the page" and not have performance problems. If changing the settings improves your performance and your CPU is maximized when the changed back anti-virus software, plug-ins, or popup blockers are likely to be the cause.
3. Compare to other PCs with similar configurations and performance on the same network.
Reason: This helps to troubleshoot differences in performance between Internet bandwidth and desktop computer issues. We may find that certain departments within a single company using the same systems have slightly $0different configurations, i.e. the development and sales departments may be using the same anti-virus software with different security level settings.
4. Disable anti-virus software, plug-ins, popup blockers and spyware software one at a time to isolate the culprit.
Reason: These applications often set strict parameters on Javascript security, which can significantly slow performance. It may be unnoticeable when visiting most sites on the Web, but loading Project Insight's JavaScript $0application code into the browser requires more browser-based code execution than the average site. Security software will slow the execution of these applications while they check for malicious code. If this is the case, you may find settings or site "trusts" that you can configure with your security software that will make an exception for the Project Insight pages so that it bypasses the process of analyzing the code prior to execution.

NOTE: McAfee Managed Virus Scan and McAfee Virus Scan Users $0$0McAfee Managed Virus Scan has a feature called "Script Scan" which is known to cause IE to run slowly when javascript is sent to the browser. To solve this, you MUST disable the "Script Scan" feature on the McAfee web site. Disabling the McAfee Managed Virus Scan software on the desktop DOES NOT DISABLE the "Script Scan" feature and the performance problems will persist. Contact Techical Support for the Specific McAfee Managed Virus Scan and McAfee Virus Scan FAQ.

5. Try using an alternative browser
Reason: Different Web browsers, such as Firefox and Internet Explorer, should have similar performance results on the same PC. This test assumes that both browsers are recent versions that are kept up-to-date by their providers. For example, Internet Explorer and Firefox are both supported with regular updates on the Microsoft Windows platform, but Internet Explorer is only available in an older version for Apple Mac. If performance with one is significantly different than the other, we will want to examine configurations and plug-ins to see if we can pinpoint any specific problems. If an alternative browser performs significantly better than IE, anti-virus software, plug-ins, popup blockers or spyware may be the culprit.
6. Run tracert to look for low performance points
Reason: Tracert can help to detect latency at connectivity points between the computer accessing Project Insight and the Project Insight servers. Tracert results may be copied into an email and sent to support@projectinsight.net for analysis. Although not always an accurate measure of network performance, tracert statistics can sometimes help to locate trouble spots within the connectivity path. Tracert syntax and help may be found using the command "tracert /?" (without the quotation marks) from a PC command prompt. Further information may be obtained by using the search in Microsoft Windows help on tracert as the keyword.
7. Run test after normal business hours
Reason: If there is a major noticeable difference between business hours and non-business hours, this could indicate network traffic problems as the culprit during heavy use periods.
8. Run test over another network (i.e. home).
Reason: This can help to check for performance on different networks and different computers. If you have a notebook computer that you can use on different networks, it can further assist in the comparison.
9. Reference the attached file to change the Advanced Internet Options in Internet Explorer.
Reason: The settings in the attached file have been tested to resolve performance issues in one particular customer issue with performance problems. At this time, it is unknown which specific setting change made the difference, but the end result was a significant improvement. When following through with this step, please note the changes made to your browser and report the results back to Project Insight Support so that we can update this article with more specific advanced Internet options settings recommendations.

11. Examine specific page content size if only certain pages appear to be slow.
Reason: Just as with any Web site, the more content which must download to display a page in Project Insight, the longer it will take to display that page. On some pages, your browser options for "Page -> Properties" may be able to display the number of bytes on the page so that you can compare to the size of other pages which do not take as long to display. You can often reduce the amount of data required to display slow loading Project Insight pages (i.e. large tasks lists or large lists of items in folder content) using display options to collapse task views in projects or using page spanning display properties in folders containing large quantities of items in the list.
