TrackerPdf.LoadSettings slow across network

[docu-track99]

Hello,

We are trying to track down an issue one of our clients is having when loading some documents across a network.

If we don't run the .LoadSettings(settings file is on local machine) then the file opens fine (15 seconds).

If we do run the .LoadSettings(settings file is on local machine) then the file very slowly (4-6 minutes).

Other facts:

The document opens fine when opened locally.
The document contains many (300+) annotations.
(When we stripped these out, the document opened fine even across the network)

So we are wondering if there is a connection internally that would make only this combination a problem?

.LoadSettings - Many Annotations - Across Network

We would appreciate any insight you may be able to offer on this problem.

Thanks.

Can you provide us your settings file you are using in .LoadSettings call ?

P.S. Please use email to send the file, don't publish it on the forum. You can use support@pdf-xchange.com - please include a link/reference to this forum thread in the email body.

One possible problem - your client has really slow network. It may be bandwith problem or even high latency problem (settings are read using small block size, so it also may be a problem).
But in most cases Settings are not so big, so it should not case such serious slowdown. Maybe user also open some PDF files across network?

We will email you the settings file? But why would removing all the annotations make the problem go away? What is the connection between the large number of annotations and the settings file?

Hi docu-track99,

I recieved your file and will pass that on to Lzcat. I can't answer your question so I'll be leaving that to him. It's the week end now in Europe so there may be no response until Monday now...

There is nothing specific in your settings, unless the client PC has 256Mb of RAM or less - in this case 10% is not enough for effective caching.

Possible connection between annotaions and sections is Comments Pane - when it is opened it starts to enumurate comments on all pages. Of cource there shoud be no such slowdown, but if the network is a VPN over modem connection or something similar ...

Also, there may be alot of side effects after call LoadSettings, so problem may be different.

By the way, which build of Viewer are you using? The settings are pretty old, made by a version released more than 2 years ago, and maye not correctly load using recent and improved versions.
