Parcel Editor seems slow

MarkVolz — Mon, 16 Aug 2010 15:30:09 GMT

I have noticed that Arc 10x seems pretty slow compared to 9.x. I have noticed that the new parcel editor seems particularly slow. I will often wait about 15 seconds before I am allowed to edit a parcel.

My machine is rather new - core 2, 4 GB ram, decent graphics card. Does anyone have any thoughts as to how I can speed the system up?

Is your data on a server or is it stored on a local drive?

Re: Parcel Editor seems slow

The data is on a server. However, I would expect a fast speed as I have a 1,000 Mbps connection that is shared with four other users.

Could there possibly be anything you have in a shapefile format that it might be attempting to snap to? We are finding it to be a nightmare with snapping to shapefiles over a server.....

How many parcels do you have in your parcel fabric?

I have found that recalculating indexes on the parcels, lines, points and linepoints tables after migration really helps with speeding things up.

To recalculate indexes on the parcel fabric feature classes, right-click the fabric in ArcCatalog or the Catalog window and click Properties to open up the Parcel Fabric Properties dialog box. Click the Fabric Classes tab and select the feature class in the drop-down for which you want to recalculate indexes and click properties.

Click Recalculate to recalculate the indexes for the fabric feature class.

At v.10.0 PARCEL EDITOR the editing experience is VERY slow.... almost to the point where you want to throw your computer.... 😞

We did not experience this kind of performance degradation at 9.3.1.

I cannot wait for SP1 - i hope it addresses performance and a whole host of other issues!!!!

Hello David,

I've tried to reproduce your performance degradation on SQL Server 2008 with a copy of your data. I cannot reproduce any noticeable slowdown, but would like to know more about the SQL Server configuration. Can you please submit a tech support request and then let me know what the incident # is? They should be able to get to the bottom of it.

Thanks

Chris

Maybe the following bit of info may help:

In my particular case, I had been working with an mxd using ArcMap 9.3. and everything worked fine. Once I upgraded to 10.0, I started experiencing poor performance using that particular mxd. I have done some limited testing and this is what I have found:

The mxd was using feature classes from a personal geodatabase, except for one layer which was a shapefile. (This polygon shapefile was received from another contractor and it turns out that this was the "offending" layer.)

This shapefile contained a multipart polygon.

It was this multipart polygon that was responsible for the poor performance.

The fix was to edit the layer in order to explode the polygon using the "Explode Multipart Feature" tool. The original shapefile contained only one multipart polygon. Once I exploded it, my performance issues went away. (Note: after exploding, the one polygon turned into 229 polygons.)

Hi Chris, and fellow users,
We just started using the standard editing tools, and I agree, it is verey slow! We have a seamless geodatabase stored on an ArcGIS Server Basic Enterprise (SDE+MS SQL 2003) OS is MS 2000, and the network about 30 users on Dell's Optiplex 745, the problem is that the geodatabase containd over 2.4 million parcels polygons and more than 9 million parcel boundary lines. Our parcel model use 6 topolgy rules. We did not have those problems with 9.3.1

Chris, I hope that you can use the sample I sent you to look for the slow response. Other concern is that the parcel editor tools do not work with our parcel model, only with the new, and according what I heard at the ESRI conference in San Diego, the new parcel model is for geodatabases about one quarter the size of ours.

Hello Emilio and others,

I'm trying to understand the performance issues that everyone has been reporting. Since the Parcel Fabric is comprised of a series of feature classes and tables, it shouldn't be any slower than other layers. Things like copy/paste and import XML workspace, etc. will tend to have a slower performance because the shear girth of the dataset.

To really get to the bottom of the performance issue, I would urge you to open a tech support request and supply just the 9.3.1 data. The tech support technician should be able to perform the test on 9.3.1 and then the same test on 10.0 to compare.

As for the question about Parcel Fabric size, there is no limitation on the amount of data loaded into the Parcel Fabric. The size would be governed only by the available disc space on the Server. Of course, with very large datasets, database tuning becomes more important. I would also make sure the department hosting the data (IT) is in-line with ESRI's best practices for ArcSDE Server administration.

Hope this helps, please respond with tech support incident numbers so that I can track progress.

I don't get that option when I follow your instructions. Is that available for ArcMap 10 Geodatabase?

How many parcels do you have in your parcel fabric?

To recalculate indexes on the parcel fabric feature classes, right-click the fabric in ArcCatalog or the Catalog window and click Properties to open up the Parcel Fabric Properties dialog box.

Click Recalculate to recalculate the indexes for the fabric feature class.

Yes, the option to recalculate spatial indexes exists for a version 10 GDB. You'll have to navigate to the Parcels and Lines classes of the Parcel Fabric via the Parcel Fabric property page. I've included a screenshot above, please let me know if you have any other questions.

Here is a generic link to how calculating spatial indexes optimizes datasets.

I don't seem to have that option to "recalculate indexes". I can add or delete an index. . . I'm using a personal geodatabase as my database

Re: Parcel Editor seems slow

DianeRodrigues — Tue, 09 Aug 2011 17:44:42 GMT

Today the speed has become even slower (I didn't think that was possible). I'm not sure why. Originally I thought my older PC was the problem causing my Parcel Fabric to crawl but it's doing it on my new machine as well (Win7 64bit 8GB RAM i5 @ 3.3ghz RADEON HD 6450 1GB)

Does the parcel fabric size cause the problem? My fabric holds about 85,000 parcels, 250,000 points, 550,000 lines. Any other recommendations besides reindexing which I can't seem to do since it doesn't provide that option?

Re: Parcel Editor seems slow

MarkVolz — Tue, 09 Aug 2011 17:57:39 GMT

FYI:

1) Someone mentioned to me that moving the parcel fabric to a local drive, instead of on the network made the parcel editor faster. That seems to have helped out.

2) Another issue I had with my application is that ArcGIS seemed crash prone. ESRI support mentioned if that I should clear C:\Users\user\AppData\Roaming\ESRI\Local Caches. It seems to have helped.

Re: Parcel Editor seems slow

DianeRodrigues — Tue, 09 Aug 2011 20:20:58 GMT

Thanks for the recommendation unfortunately it didn't solve my problem. It sadly made it worse which was a surprise. I did run a parcel fabric check and have a few errors. maybe I just have one bad parcel goofing up the whole lot. I think I'll work on fixing that until I hear how to reindex.

Re: Parcel Editor seems slow

MarkVolz — Tue, 09 Aug 2011 20:25:06 GMT

Not being an expert, here are a couple things I would try:

*use the mxd defrager.
*open a new mxd and bring only the parcel fabric in. If you notice a speed difference then your issue is with the mxd (which can be replaced)

DianeRodrigues — Wed, 10 Aug 2011 17:55:54 GMT

Darn those ideas didn't work either. How I wish it was an easy solution! Oh well I have time to work on it again today. I think I'll just focus on cleaning up Fabric Errors from the original import. Who knows if I get lucky maybe once they are all cleaned out I'll see an increase in speed.

Thanks for trying though Mark. I have found MXD's causing problems in the past it would have been nice if it was the same for this problem.

We've had slow editing for a while. I'm sure ESRI knows this is an issue.

Re: Parcel Editor seems slow

DianeRodrigues — Fri, 26 Aug 2011 17:11:53 GMT

Okay folks I found the solution for me.

Do not use a personal Geodatabase. Use as File Geodatabse. File Geodatabase allows you to reindex unlike the Personal Geodatabase. Now I just need to figure out how the heck I move over my data . . . ESRI REALLY needs to release a book on how to properly use these tools. Some of us can't go to training 😞
