NAS and Parallelism

ldreamsl

Hi to everybody,
my problem is this:

1) I have installed the NAS on the server with only 1 license

2) I have realized a based system on ASP.NET, that Query through MSMQ on the SQL DateBase Navision

3) If a Query employs a lot of time to finish, all the other users they stay in attended

4) exists a way for not stopping the Process but to realize a parallelism of the transactions?

Nas is not multithreaded, but there is such things as commerce gateway that handles mulitple instances of NAS.

If you use multiple timers, NAS will handle the different transactions parallel (multi threaded).

No, because if the NAS is working, even if an other demand arrive, it does not answer.

You want to run the same function multithreaded ... . I was talking about different functions running in timers. Two different things ... I can better shut up ](*,) .

Hi,

as the other already mentioned:
NAS is not multithreaded, therefore when the NAS is running a transaction, everything else has to wait until this transaction is finished.

For Commerce Gateway it is a little bit different scenario, because it is working asynchronous, which means that there is no immediatly response like in a web application.

Currently the only way is to have multiple instances of NAS running.

Another way may be to change the programming so that the NAS has to handle only short-timed small transactions like

User A, B and C want to get data. They send the request parallel.
NAS is running A, then B, then C.
But if each request is split up into different requests it may help to get the following response:
User A, B and C send request parallel. Request A consists of 4, B of 2 and C of 3 smaller requests.

User NAS
A1 (needs some time)
B1 A1
C1 B1
A2 C1
B2 A2
C2 B2
A3 C2
C3 A3
A4 C3
A4
