dotnet web services: Hi All,

I use .NET 2.0.

I experience huge performance problem retrieving dataset from web
service.
The dataset volume returned from WS is about 5-7 megabyte, it's take
too long.

Is it possible to compress dataset in some way in the WS send to
client, and decompress
in the client, if yes how???

Maybe there is another way to pass huge datasets from WS, maybe IIS ??

To do this asyncronously or in batches is not suitable for my problem.

Any ideas??

Thanks in advance.

I too face the similar problem.What we did is to serialize the entrie
dataset to byte array and transmits it through the wire.Before
serializing we did convert the datasets to arrays and used gzip
copression after

Datasets are known for their penalty caused by their size. So an immediate
question is: Are you sure you actually are in need of a dataset?

My experience with DS are more or less: Do not use!
A better approach is most often this:

You do not state the reasoning behind using the DS, but if it is just what
came out of an SQL select; I strongly suggest that you review your
systemdesign once more to eradicate use of such elements.

If you find that you can not live without, you might want to have a look at
DIME or MTOM to send the data using chunked mechanisms instead of one-shot.
