    2526'''TNG vs. Classic—Do They Behave the Same?''' 
    2627No. One important difference is that data upload speeds matter much more for TNG 
    2728than they did for Classic. TNG works differently than Classic and takes advantage of 
    28 new technologies available in browsers and servers (Web 2.0).

    3031'''What Happens When TNG Loads?''' 
     
    3839'''What Happens During Sign In?''' 
    3940When you visit your district URL, TNG pings to see if you have a session already and 
    40 redirects you to the sign in page. This is the RPC (Remote Procedure Call) back‐andforth. 
     41redirects you to the sign in page. This is the RPC (Remote Procedure Call) back‐and forth. 
    4142RPC is bi‐directional communication; TNG will also do a confirmation of your 
    4243identity handshake. This typically takes up to 2‐3 seconds to confirm if you have a 
     
    7879navigation for the My Agile Mind tab).

    80  *When you select a course, all of the navigational elements in the left hand 
    81 navigation bar are reloaded. 
    82  *The first time you select a course, the content for topic 1, page 1 is loaded. 
    83  *Performance takes a large hit the first time you select a course. Note that TNG 
     81 * When you select a course, all of the navigational elements in the left hand navigation bar are reloaded. 
     82 * The first time you select a course, the content for topic 1, page 1 is loaded. 
     83 * Performance takes a large hit the first time you select a course. Note that TNG 
    8484does NOT load every page in the topic when you choose the course and views 
    8585the first page in the topic.

    175175 
    176  *We are examining load time information for the new Biology pages—many of 
    177 these contain very large images. This might be a factor affecting performance. 
    178  *We are investigating reducing session writing to the server. 
    179  *We are investigating caching. 
    180  *There is clearly a memory leak when using Internet Explorer. We are hopeful 
    181 that this will be significantly improved when we release the version of TNG 
    182 we are developing to use the new GWT. 
    183  *We cannot fix bandwidth limitations, but we can investigate compression 
    184 and caching parameters for Internet Explorer 7 and 8. 
    185  *We are investigating optimizing our traffic.

    191187there is more than one cause for the reported issues.

    193  *Fire off a diagnostic as soon as you get a ticket about slow load times. In 
    194 either Mac or Windows, open a Terminal or Command window and ping the 
    195 district server and provide that information to Engineering. This will provide 
    196 roundtrip delay information and potentially do a traceroute. 
    197  *Pay particular attention to bandwidth and latency. Support Services can 
    198 provide a URL to a bandwidth tool. 
    199  *Ask the reporting teacher for or provide details about: what district, what 
    200 teacher, what course, what area (or areas) of TNG are slow, what time of day. 
    201 Engineering needs all of these details in order to reproduce the issue. 
    202  *Internet Explorer 7 users should bring up the Task Manager and check the 
    203 process memory when they experience poor performance and slow load 
    204 times. Internet Explorer 7 users should also check the Performance tab and 
    205 report if there is any kind of page file usage.
