RE: [OpenMap Users] help eliminating RPF 'load' time

I experienced the same problem when switching over to version 4.6. I
have not as of yet had time to investigate why, but I will be sure to
post something if I find a solution. I hope you will do the same.
Thanks.

Subject: [OpenMap Users] help eliminating RPF 'load' time
 
Greetings,
 
I am seeing a long delay for OpenMap to initialize the RPF layer. We
have approximately 17Gig of CIB1, CIB5, CIB10 all the way to GNC data
for one country. The RPF layer takes approximately 10 minutes to 'load'
although the initial scale is at full world (thus no RPF should be
displayed yet).
 
Our map files are stored on a network. There are a few things we have
tried to increase performance. First we tried making one 'master' A.TOC
file for all the directories. The performance boost here was nominal.
Then we generated the 'master' A.TOC file locally on the client. This
netted us a noticeable performance increase. However, that is not a
practical solution for our situation.
 
Are there any property file changes I can make? Something that would do
lazy loading so the user doesn't take the initial performance hit up
front? Are there recommendations as to how to build paths, A.TOC files,
etc?
 
Sincerely,
Leah Wong
