Question

slow flipping between pages

Updated September 6, 2016

asked on September 2, 2016

Hello, we just installed Laserfiche 10.1 and SQL on 2 separate servers. Our users have been complaining of that it takes 5-10 seconds to open a file, and to flip between pages. We looked at CPU, Memory and Network throughput and none are peaking during those reported times of slowness.

We are currently recording stats from both server and user pc to ascertain where the bottleneck is.

I would just like to ask:

Are there other areas that I should be checking?

Is there something we need to look/tune in the database?

Is there maybe a patch/fix for this issue? (we have not applied Update 1)

Thanks!

Thank you John and Brian for your suggestions. I may have found the issue and resolved it.

Just some added info and my comments, we not only upgraded to 10.1 (actually a fresh install) but also the first time we moved the system from on-prem to a cloud hosting service. So we made sure that hardware and bandwidth were slightly over-compensated (even between Laserfiche server and the file/repository server). We also made sure that the ports (as defined in: https://www.laserfiche.com/solutionexchange/best-practices-for-laserfiche-configuration/) were enabled. Our IPS/IDS has been running side-by-side with Laserfiche since we had version 8, so I don't think there should be any conflict (but I will keep this in the radar).

After investigating further, when I loosely used the term 'our users have been complaining', I was wrong. Not all (100%) users were affected. It turns out that the issue was local to their individual computers (for about 5 users). After doing a bit of performance-tuning on each of them (ie: applying windows updates, restarting pending reboots, disabling unwanted startup programs, cleaning the registry, etc.) the performance seem to have gone back to normal.

Inspite of this, I learned a little bit more about Laserfiche from your suggestions.

Thanks again, and have a great day!

CPU, disk, memory and network stats just came in and none of them are peaking/pegging. But as I write this message, users are having a 5-10 sec wait flipping between pages in Laserfiche 10.1 client.

Lots of places to look at, but here are a few to start with.

1. Is it slow if you run the client on the Laserfiche Server?

2. What was the Laserfiche topology before?(DB/Laserfiche Server/Storage) vs now?

3. Are searches/opening metadata slow, or just when showing images?

Thank you John for your feedback. Answers to your questions:

1. No it is not slow.

2. Topology of before and now are the same. Laserfiche is on 1 box, and DB is on another box. Hardware specs are the same as before and now, Laserfiche Server (2 CPU, 8GB Memory), SQL Server (4 CPU, 16GB).

3. Users did not complain about searches being slow, just particularly opening files and flipping thru pages. (varies 5-10 secs).

Thanks in advance for any suggestions.

If the same operations are not slow when done on the server versus slow on remote client, that points towards something being blocked somewhere. I've seen Intrusion Detection Systems flag traffic as well as antivirus cause issues with slowness. I would look at those first as Laserfiche generally uses http/https ports by default.

File and page operations require pulling data from the volumes. If those are slow but database-only operations like browsing or metadata actions are fast, I would look to the connection to the file servers. Remember that all data transfer is mediated by the Laserfiche server; clients don't read from volumes directly.
