Suddenly, KMM has become extremely slow. For example, just to "accept" a downloaded transaction, it takes 5 to 7 seconds! I have a quad core + 6G machine running Kubuntu and KDE 4.5.1. I believe the last time KMM was running normally, I had KDE 4.4 and KMM 3.98. Turning off desktop effect didn't help either. Everything else is running quite normally as far as I can tell, so this doesn't seem like KDE problem. Consistency check initially complained about clear text passwords that needed to be saved to KDE wallet and missing security prices. After I took care of those, data file is consistent.

I noticed there is a performance test under tools menu. I don't know what exactly it does, but selecting that menu item, the CPU usage on one of my core goes to 100% with KMM taking up almost 98% of total CPU utilization. I let it continue and KMM response came back after 30 minutes.

I started KMM from console and didn't really notice any logs after "endDocument". The last two messages when I exited KMM were,

QFile::remove: Empty or null file name
kmymoney(4274)/kdecore (KConfigSkeleton) KCoreConfigSkeleton::writeConfig:

Any suggestion what might be going on?

Thanks

The log looks normal. Can you tell us a bit more about your configuration?
Your Qt and KDE version, your distro?

You were using 3.98.1 previously, right?

I have kubuntu 10.04 with KDE 4.5.1 and QT 4.7 RC1. I normally keep my KMM version up-to-date using http://ppa.launchpad.net/claydoh/kmymoney2-kde4/ubuntu so I must have had 3.98.1, prior to upgrading 4.5

Also, here are the performance numbers from console.

I can't tell if these are normal, but the performance test does run for half an hour.

Thanks for the quick response.

Any idea on what might be going on? Do the performance numbers look normal? Has anyone using kubuntu 10.04+kde 4.5.1+KMM 4.5 noticed any such slowness?

Thanks

Those numbers are a little high, but yes, we are aware there are performance issues and we are working on that.

Could it be that as it is built against 10.04's stock KDE/Qt versions (4.4.2 and Qt 4.6 vs KDE 4.5.1 and Qt 4.7 rc-something), that this could be a factor?

I have not bult any Maverick packages for KMM as 4.5 is natively available there, and I am not seeing any slowness on my 7 year old laptop (10.10 is may main OS at the moment)

Running my ppa packaged KMM on my Lucid Boxee system with a relatively recent Athlon dual core setup doesn't seem slow, but that is in comparison to my ancient laptop Definitely no slowness anywhere near to what you are seeing - I only keep current year checking account info, however.

KDE 4.5.1 does not run on Qt 4.7. Or at least it shouldn't. Is Kubuntu messing up dependencies again?

I'm on 4.6 and I see some problems but nowhere near that. It's likely related to video drivers.

in kubuntu the kde 4.5.1 ppa is backported from maverick's setup, which includes qt 4.7 (rc1 at the moment)

And iirc Fedora also seem to be using 4.7.

My P4-M 2.0 laptop w/1 gb ram running 10.10 is slow on the performance test, but that is due to my vintage hardware and having quite a few open/running apps

This is my 10.04/KDE4.5.1/Qt4.7 machine

KDE 4.5.x depends on Qt 4.6. The distros are messing up. I know, because the discussion to up the dependency to Qt 4.7 for KDE 4.6 is still going on.

Back to the point, it's interesting how different the numbers are for the same distro. There seem to be a couple of similar cases of performance problems, and they are all Kubuntu-related.

is there any way this could be dbus related? it sounds very similar to the Dolphin hang/freeze in KDE 4.5.

No, dbus is only very loosely used.
We have fixed an issue with icon caching. Can you update the snapshot PPA and have users test from there?

After I recreate the snapshot ppa - haven't done those in a while. Will do soon -Sunday PM or Monday.

Just an update. Even after upgrading to the latest Kubuntu 10.10 and KDE 4.5.2, KMM still feels slow. A simple transaction entry takes 3 to 5 seconds. I noticed that the KMM is still at 4.5.0 in the latest Kubuntu, so wasn't really expecting it to get fixed; but I am hoping the fixed packages are available pretty soon.

Cheers

The manual says that a performance check "runs a test on your file". Does that mean measurements will depend on what's in your file? For what it's worth, I am running KMM 1.0.5 under KDE3.5.0 on a dual core 3.06 GHz Xeon (4GB). My kmm file is 470 KB an contains tons of data. Here are my times:

It seems that your response for "totalBalance(Asset) is the only test that's really slow compared to mine. But my test didn't take half an hour to run; it took just 10 seconds.

I have the exact same problem described in OP. Kmymoney is extremely sluggish - even accepting a transaction takes 4-5 seconds. I am converting from Microsoft money and have a large number of accounts and transactions (kmymoney file size is 380kb). I can't believe that this is the cause for slow performance of kmymoney. MS Money runs very smooth with those accounts and transactions. My search for a fix to this problem landed me here. Is there any update/solution to this problem? Any help would be greatly appreciated.

I am using opensuse 11.3 and KDE 4.5.

Thanks.
