Prev Breadcrumb - upload transfer

[Janusz]

Hi,
On some locations with slow internet connections (max upload 512kb/s and shared with few computers) I am experiencing important lag in responce when the table has text cells with few pages of data in it per every row. It is not an issue on normal connection when you have at least few Mb/s - beacuse then everything works perfectly.

What I noticed - the main cause for this is the request to go to the previous breadcrumb nuGetBreadcrumb(x-1) which seems - it is sending relativelly big number of data from computer to the server (twice more data is sent from computer to server than from server to computer).
Please find enclosed some measurement of tranfers for typical case of database usage.

I know that it is not an issue of nuBuilder usage in normal enviromnent - but maybe some small optimisation by the ocasion of new release could improve such cases as well - when the internet connection is poor.

Janusz,

I agree. I'll look at it as soon as I get a chance.

Hi Steven,
I did some test to minimize the lag and noticed that the same form placed in the iFrame is about twice faster comparing to the form in normal window (twice smaller internet speed rates required for upload). Another optimisation was to remove the "heavy column" from the browse table and leaving only short title which is as well reducing the upload rate. The download rate for all the cases were identical.

Just FYI please find enclosed the rates measurement (done on normal internet) - maybe it will be helpfull in case you would have a chance to look at that subject.
