Slow loading of stop locations onto the network

[SashikanthGurram1]

I am trying to load the stop locations onto the network in order to get the shortest routes that goes through these stop locations. I did this in the past and at that time the locations have loaded fairly fast. But then I had used the zlevel information to construct a new network and tried to load the same locations again. This time, the loading process is painfully slow. It is taking almost 9-10 hours to load around 8400 point locations onto the network. I am not sure what made the process to be slow this time around.

If you have any idea with regard to this issue, please share your thoughts.

Slow loading usually means that there is a missing spatial index or the existing index is bad.

You can try to use the normal identify of a feature on your network and see how fast that is. If that is also slow then it also points to a bad index. You will need to re-index or create an index on your street features.

Ok.

When I was doing this earlier, I used the shapefiles with only single projection system.

Now, I have used the roadway lengths and travel times to compute the short paths. For this I projected the roadway shapefiles. So, now I have shapefiles with GCS_WGS_1984 and NAD_1983_UTM_Zone_17N projection systems.

Do you think this is causing the issue? Further, how can I rebuild the spatial index? I have tried to re-build the spatial index for the projected shapefiles but could not find a recalculate button to re-build the spatial index.

In the catalog, bring up the properties of the shape file. Then click on the Indexes tab. Towards the bottom right, it should have a way to add, delete, update the spatial index.
If you are unable to find this way, then you can use the GP tool to Add Spatial Index.
