Hello Everyone,
I am new to GeoServer and I just had a performance question. I am
interested in displaying the Federal Aviation Administrations pilot charts.
I attempted to store a chart on geoserver, but it seems very slow when I
preview it in OpenLayers. Each tile takes anywhere from 2 to 4 seconds to
load.
The source Los_Angeles_SEC_101.tif file is 69 MB and is available for
download here:
http://aeronav.faa.gov/content/aeronav/sectional_files/Los_Angeles_101.zip
Which was listed on this page:
https://www.faa.gov/air_traffic/flight_info/aeronav/digital_products/vfr/
Here are the steps I used to set up my GeoServer.
1. I deployed tomcat on Amazon Web Services then copied geoserver.war
with the chart added inside the data folder.
2. http://geoserver2.us-east-1.elasticbeanstalk.com/web/
3. Changed Administrator password
4. Deleted all existing workspaces
5. Created a new workspace faa
6. Add a new Store
1. GeoTIFF
1. Workspace: faa
2. Data Source Name: Los Angeles
3. Description: 101 – Jun 22 2017
4. Enabled: checked
5. URL: file:data/Los_Angeles_101/Los_Angeles_SEC_101.tif
7. New Layer - Los_Angeles_SEC_101
1. Publish
2. Data
1. Declared SRS - I am guess on this one. I chose
WRF_Lambert_Conformal_Conic 2
2. SRS handling - I am guess on this one. I chose keep native
3. Save
8. Layer Preview
9.
http://geoserver2.us-east-1.elasticbeanstalk.com/faa/wms?service=WMS&version=1.1.0&request=GetMap&layers=faa:Los_Angeles_SEC_101&styles=&bbox=-351020.4576958068,-245067.92468142207,353646.13725918817,277738.9876785168&width=768&height=569&srs=EPSG:45555&format=application/openlayers
10. If I hit the zoom out button 3 times, I see my chart.
Now if I try and move around, zoom in and out, etc. Each tile takes
anywhere from 2-4 seconds. I really need a solution that can render in less
than 500ms. Is this possible? What do I need to do to get the server
responding faster?
Best,
Scott
