Laserfiche Forms: Slowness in form loading, navigation

Forms
Updated April 8, 2022
asked on April 8, 2016 • Show version history

Hi,

We are working on a timesheet project, with good amount of fields and CSS & JavaScript running in the background. The flow of the form is Submitter --> Approver1 --> Approver2 --> Repository.

 

Issue 1: Slowness of the portal

a. It takes approx. 40 seconds for form to load (for any user submitter or approver)

b. It takes approx. 40-50 seconds when user submits or approves the form.

 

Issue 2: Slowness during lookup rules:

We have configured one lookup rule:

User inputs: Firstname, Lastname

Lookup calculates: EmployeeCode, Approval Managers 1 and Approval Managers 2.

After entering FirstName & LastName, it takes 30-35 seconds to populate the employeecode, approval manager 1 and approval manager 2 fields.

Note: We have used Laserfiche out of the box, "Lookup rules" section to configure the criteria.

 

Don't know what is causing the slowness in both the cases. Yes there is good amount (3000lines) of JavaScript running but the calculations in the forms are running quick. So I don't think it is causing the slowness issue.

Any advise will be appreciated??

 

Thank You

Dhruv Shah

You may not have a similar installation to ours, but we also had performance issues with Forms after upgrading to 10.  We disabled NetBIOS on the web server Forms is installed on and it fixed our issue.  May be worth a try.

We had a similar issue. + - 40 seconds per form especially on the mobile app.

 

Disabled Netbios and now it opens in 2 seconds max. 

 

Thanks

Hello there,

Our system has recently been effected by extreme slowness.  I went ahead and disabled netbios on our server, but it didn't make any difference.  Like the other individual that posted, it is taking around a minute to pull up forms and tasks.  We upgraded to 10 a while back, but everything was working just fine until about five days ago.  We did the usual "what has changed" troubleshooting, but have come up empty. Nothing has changed, the system just decided to become really sluggish.  We have tried the following:

  • Rebooting of both Forms server and Database servers
  • Moving the virtual servers from host to host, and to the same host
  • ensured the database server was performing as expected (queries are running quickly)
  • Checked hardware, and performance
  • Several minor items - such as restarting LF services and the like.

 

Any suggestions as to what we could possibly try next would be appreciated. 

 

Thanks,

Tito, Idaho Falls School District 91 LF Admin

Have you figured out your problem?  Facing similar here, even after disabling NetBIOS.

Thanks!

Yes, our issue ended up being apart from anything LaserFiche related.  After dealing with our slow forms issues we noticed another piece of software not as commonly used running extremely slow.  We then had out server admin take a look at the servers and related hardware.  Our results were that both Laserfiche and the other piece of software were running off the same hardware, and we narrowed it down to a faulty data cable connecting that piece of hardware to our network.  We replaced the cable and Forms immediately sped back up.  If any software configs aren't working for you, and you are running a local data center maybe looking into hardware issues would be the next step.

Just would like to add that I had a RIO customer with 4 different Win2012R2 servers configured.  Full SQL on it's own server with 16Gb of RAM.  Slowness overall but mostly noticed in Forms.  45 or 50sec to open a form.

This turned out to be the virtual environment and the physical server it all resided on.  Too many VM's for resources available using Hyper-V.  One of the major issues was a memory leak due to the virtual environment.  Client has since upgraded to a new VM host and migrated all to the new virtual environment and it is lightning fast now.

Thanks for the suggestion Johnathan.  We are also running into slow forms and especially forms field lookups.  All traces/logs/case suggestions have shown nothing.  We will try the NetBIOS.

Dhruv, just to check, have you commented out all your CSS code and tried the field lookups to check the speed?  As in create a lookup that is not dependent on CSS code but just something to tests?

Thanks for the suggestion Jonathan. We have disabled NETBIOS on the server and it seems to be working. Will continue testing for few days to monitor the speed performance and update.

 

Hi Chris, since there are multiple conditions on which lookup is performed the "Autofill" button comes up. We are running a script which hides the button and performs lookup action on Click.

Yes you are right, since it based on code it takes time, but as soon as I make it independent of the script it works quick. But then we have the "Autofill" button which appears and needs to clicked everytime.

Are you aware of any workaround, which can make the lookup quick with "Autofill" hidden?

Thank you so very much Jonathan. The suggestion has worked wonders!! The performance is now very good.

Thanks again!

Is this happening all the time or only running on a laptop disconnected from its usual domain? What operating systems have you seen it on?
