[mapguide-users] MGE performance. It's soooooo Slllllllooooooowwww

The trick is multiple layers.  One layer zoomed out that has been generalized, then zoom in to a more accurate layer.

Something else I've found is that you just cannot show as much data in the initial view in MGE like you could in MG6.x.  I've seen many MG6.x sites that had dozens of layers turned on in the initial view that just made no sense to be on at that view scale.  But... the old technology handled it fine, so people expect the new technology to behave exactly like the old one.

I guess what I'm trying to say is, you need to be much more 'prudent' with your display ranges, and what layers really need to be turned on, in MGE to get decent performance.

I agree on using the AJAX viewer.  Put the data in SQL server, index the geom, use AJAX and fly...if you need help, let me know.

What, specifically, can't you do with the AJAX viewer? I've certainly noticed the serious performance slowdown with Fusion (vs AJAX), which is why I'm still using the AJAX viewer, myself. My suggestion would be to try to figure out if you really can't do what you'd like with the AJAX viewer (if it's fast enough for you, I mean).

Hi,

We have been working on a complete migration from 6.5 to MGE as a pilot to

see if we can actually move to the new platform since the 6.5 software is no

longer supported.

We have brought across everything from our 6.5 app to the new MGE framework

(using fusion due to the required functionality), we have also made alot of

changes in an attempt to speed up our data.  We currently use SQL for our

db's, but we've went so far as to setup static tables instead of news in the

db, we have also imported data and stored in directly in the SDF's to try

and speed things up, but nothing we have tried really makes a difference.

The performance of MGE using Fusion is unbelievabley slow and there doesn't

seem to be anything we can do.

Take for example a simple SDF3 of parcels.  We created an SDF3 that has

about 23k parcels and instead of linking it to a db, we attached the data to

the parcels in an attempt to speed up the flyouts in MGE.  The data is only

a simple ID, and another db field for testing purposes.  We used the tooltip

method in MGE and we also tried using an aspx page to load the simple

dataset instead of the tooltip directly accessing the data from the

attribute list in MGE.   The results were the same, slow flyout loading

times.  To make things worse, if we turned on a layer which has alot of

data, then tested the flyouts again for the parcels, it takes about 15secs

for the flyout to appear.  Obviously thats not acceptable.

I don't know what else we can do with all of this.  The performance of MGE

is absolutely horrible, and after using 6.5 for so long we actually are

considering going to a completely different GIS software. (Esri?)

How are others dealign with this performance issue?  The basic AJAX viewer

is faster, but you also don't have the tools and flexablitly that you do

with the Fusion setup.

Thanks.
