Livelink 9.7.1 Performance Issue

[hmchapman]

Hi,

We are trying to go live with OpenText document management. Server is Livelink 9.7.1. Client is currently 10.1 SP3 with Office 2003 SP3 as the integrated office suite.

We are seeing what we think is terrible performance, but we are not sure if its a setting somewhere or if its just the way Livelink works.

Time to open a 50K word document is about 10 or 11 seconds on a standard XP desktop. A 6 Meg text file opens in about 1/2 that. I have tried it on a stripped down XP machine, with just the bits necessary to run the Office and Livelink but that doesn't help.

I have run network traces and can't really see any issues except that there seems to be a lot of XML moving back and forth.

Does anyone have any suggestions on what I can try to remedy this? The environment is three web servers, indexing server and file server running in seperate virtual Windows Server 2008 R2 on VMWare. The datbase is SQL 2008 R2 Sp1 running on Server 2008 R2 on a physical box. Based on looking at the server performance, the servers aren't the issue. When doing mass imports we are getting about 60K documents an hour.

The system has about 2M documents currently imported and we capped the documents at 1000 per directory which sounds like it was a problem in prior versions but not 9.7.1

Finally, we have a lab environment running the 10.2 beta and performance is exactly the same (or withing a second)

Any help is appreciated.

I assume by Client you are referring to Livelink Explorer / Enterprise Connect ? can you confirm which ?

Have you reviewed the log files such as Summary timings logs and Threads to look for bottlenecks ?

Have you confirmed the download times with and without the LE/EC client e.g. using a Web Browser ?

Have you confirmed the servers versions are supported by OT for the 9.7.1 release ?

Have you spoken to OT Support ?

Yes Enterprise Connect. Opening the file in the browser interface seems to be about 1/2 the time of opening using the fat client on the same desktop.

We did work with an integrator and as far as I know all version we are using are supported in our configuration. Unfortunately I came into this late to work on the performance and was not really involved in the OT config.

No, trying to get help from OT support but no luck so far. Their turn around time on calls seems to be awful. We are supposed to have our first 100 users go live this weekend and are really struggling to try and fix the performance. Since we are not yet "live" we seem to sink to the bottom of the queue.

I haven't looked at the logs you are talking about but I will try and do so. When we started this the object importer was not available on V10 so we put in 9.7.1 server side. All our processes right now are based on the 9.7.1 importer so upgrading the server to 10.1 or 10.2 beta right now is not an option.

As I said, right now this occurs with one client but we are importing 60K documents an hour server side so I am thinking we don't have some server bottleneck.

Thanks for the suggestions.

As a simple tweak you may want to separate your lapi/websvcs traffic form the end users.If a Livelink FE has about 3 GB to spare then you can run about 3 instances more which would give you 15 threads as opposed to 5 threads running in single machine.
As greg said only analyzing summarytimings can one know whether it is realted to thread contention or so.in nay starting environment I basically recommend this

a Hardware LB that can give you vanity URL's to livelink pools

2 FE on 2 boxes for livelink gui users
2 FE on the same 2 boxes for livelink websvcs/lapi/connect users
A beefy admin server to run search and agent/notification chores

Just having livelink FEnds on virtual machines is really fine as well

Well, if I called the wrong number, why did you answer the phone?

We are running into the same issue where have less than 10 users on our prod systems config'd by OT. Uploading a document is 3 times slower via EC client 10.1 than web.

Ran fiddler logs and found the EC client is running 30 statements to the web interface's 6. I don't know what the difference should be but the HTTP calls seem to be excessive from the EC client.

Looking for assistance in making the configurations more efficient and faster.

We are on LiveLink 9.7.1/IIS 7/Win XP/EC 10.1/Win Server 2008 sp2
11 gig RAM server
1 cpu 2566 mhz server

Have you tried the new EC client as I am sure there will be some fixes for bugs and performance in that area ?

Just installed the new EC client 10.2 and found that from MS Word that the number of http calls decreased by 2. That is when running the 10.1 and fiddler for just running a file upload (tiny - less than 1k) fiddler found 30 calls. In 10.2, the same size of file and running fiddler found that there was 28 calls. I am sure that there could be some improvements that can be made from the Word and the EC client in total.

This is the most important method as users are spending 90% of their time in word.

The other area of concern is when first opening the Web interface, and going into the web dav interface via the "drag & drop" tab. I see 12 seconds when clicking on the tab.

Sometimes opening the llworkspace takes 1 minute.

Any ways to improve the web performance would be greatly appreciated.

Have you tried restarting the web client service on the machine ? - this fixed it for us and was a one time only needed fix on some Windows XP clients.

Dont know exatly why it fixed it but it did.

 

[NewLiveLinker]

We have the web client service turned off due to a issue this causses with versions within the web interface for drag and drop.

10.1 is our default version for Enteprise Connect as we are looking to put in some addtional remote cache servers to resolve latency sensitivitiy.

I am facing issues with uploading large size PDF documents. Running 9.7.1 EC10.2 Server 2008 . It seems there is a cap ( I guess in the range of 30 - 40 Mb ) . I have documents running upto 200 MB.

Also there seems to be an issue with migrating .msg files - some of these files have been renamed as the subject line does not make good sense. However once moved to LiveLink , the Title automatically replicates the Subject line . Any suggestions on how to retain the original Filename in this case.
Appreciate all advices.

linklive, suggest you start a new thread as your question is significantly different from the original posters here to warrant it.
