Tap Forms incredibly slow on Retina iMac. Anybody?

[Mario Biondi]

I was using Tap Forms 5.2.4 on a Retina iMac and an iPad (High Sierra 13.2 and IOS 11.2.1). On IOS it literally flies, on iMac it is incredibly (disgustingly) slow. So now I have installed it also on my old MacBook Pro (same OSX), just to see what happens, and there too it behaves very well. No slowness whatsoever. Is anybody experiencing the same issue? Can anybody suggest a solution? I need to use the software on my iMac. MTIA

Hi Mario,

Hmm… I have a MacBook Pro Retina, but not an iMac Retina, so I can’t specifically test it on that hardware.

Might I suggest going to the Maintenance screen in the Preferences window and click the Compact Database button?

That will run some optimizations on the database file and hopefully speed it up a bit.

THanks,

Brendan

Many thanks to you, Brendan, but it’s not a problem of compacting. I did it I do not know how many times. And I have exactly the same documents on the 2 computers and on the iPad. So why on iPad the software works like a lightning, on MacBook Pro goes very well and on the Retina iMac it behaves like an old, rotten carcass? On the iMac I have most probably something which conflicts with Tap Forms. I must discover what… but how… mmmm…

Did the iMac had a repair? I find that after a repair the macbook and iPhones I had repaired did show significant loss of speed.

Hi Mario,

Which view are you using? The multi-column list view does render faster than the single-column list view. The single-column list view must calculate the height of each row, but the multi-column list view is a fixed row height, so it’s quicker to render.

[Mario Biondi]

Many thanks to both. No, Leo, my iMac 21 should be exactly as it was when I bought it 2 years ago (late 2015), nobody touched it.
And (Brendan) I have too many data in my fields, I can not see anything in multi-column list. An opera or a jazz performance can have up to 20 performers or more, and I need to see them paired with their roles or instruments (see the image as a very simple example). Otherwise which would be the use of a DB?
And anyway, I repeat, I am testing EXACTLY the same things on iMac and MacBook Pro. Terrible performance on the fist, good on the second.
I am afraid my iMac 21 (being late 2015) has some issue. Touch wood…

Hi Mario,

If you can’t see anything in the multi-column list view, it could be that it’s just collapsed. Try dragging the horizontal line that goes across just above “Default Layout”. If you drag that downwards, it should snap open the multi-column list view.

How many records do you have in this form? Is it just this form that performs poorly or is it all forms?

[Mario Biondi]

Sorry, Brendan, but evidently I can not make myself clear.
The problem is not what I can or can not see in Multi-column view. What can you see in those columns when you have 75 fields for 6600 records (or similar)?
The problem is (I use capitals in the hope of being clearer): WHY TAP FORMS IS SO INCREDIBLY SLOW on my iMac and not on my iPad?
IN ITSELF, in ALL its forms, not in this form or that.

If you would like to email me a backup of your document, I can do some profiling to find out where Tap Forms is spending all its time trying to display it. but I don’t have a Retina iMac, only a Retina MacBook Pro. So it might not be an accurate test. But there might be some clues that will help me figure it out. Email to support@tapforms.com

Many thanks for your offer, Brendan, but this is not possibile. My documents all in all set up a sort of encyclopedia of recorded music (Opera, Classical, Jazz). Thousands of records with all the relevant data. 30 years of work. Too precious for me.
I take note that probably they are composed of too many records and fields, so it takes a lot of time to display them.
Strage thing is how slow they are on Mac (both Retina iMac and non-Retina MacBook Pro) and fast on iPad.
I can simply hope that your updates (together with new versions of OSX) will address successfully the issue.

[Brendan]

One thing you could do to try and speed it up is to reduce the number of fields that are displaying in the multi-column list view. If you click the little tool button at the top-right corner of the multi-column list view you can control which fields are displayed there (and in which order). There may be fields you don’t need to see at all times there. If you select a record you will of course see all the fields for the selected record down below in the record details view.
