Speeding up form loading in v7.x

In Metastorm BPM v7 and before the Web Client has quite a large footprint and a significant number of request and responses are required to load every form (for images and included scripts mainly).

Follow is the IIS logging of opening a simple form in the Web Client (with caching in place, note all the 304 responses):

That is 30 requests verses 2 and that is for just opening a simple form. If latency is part of the issue this should have a big impact.

Content Expiration is configured in IIS:

For this to work properly I believe that the browser needs to have its caching configured for automatic (which is default I think):

A better option, would be to fix the client to download the whole lot in one go. It would be a massive perfomace gain, and should be very simple to achieve.

We pointed this out while testing a satelite uplink in the outback with Novell in Australia. Unfortunately, although the then developer on the client thought it was a great idea, he left shortly afterwards. The same problem has been arroung ever since.

Interestingly, Jerome, you are pretty much describing what we did in the version 9 Web Client. Rolling the JScripts into fewer files and the use of sprites for images has greatly reduce the the number of requests in opening forms.

Thanks...

Fantastic news. I have not had the chance to try the client on a network yet, but look forward to seeing an improvement. I do notice that form refreshes on a local syste certainly seem faster.
