Log4OM very slow

[F4BPO]

Hi Lele,

Definitely when there is a heavy load of spots on the cluster it slows down Log4OM heavily.
So i have to turn off skimmer and ft8 for sure.

But also the CW interface is very very slow, many times when I click on a macro it takes 5 seconds to start sending the code.
I use Winkeyer either with a Micro Keyer III or Nano Keyer but it is the same for both.

I see a lot of checks are done on the cluster spots maybe this slows down a lot things, is there a way to stop all this ? I am not really interested to have all sort of checks on all the spots but only the ones I click on ?!?

Everything is turned off currently, VOACAP, QRZ.com upload, HRD upload, Program Settings/Performance all off.
I only keep clublog upload to keep the live clublog.

I do not really know what to do to speed up Log4OM. Of course maybe a large majority of users do a QSO here and there and do not see what I am seeing.
Running around 100 to 150 QSOs per hour rate it becomes a real problem.

Anything else I could try ? As I am considering to change logbook but I love Log4OM as it has everything I want.

Thanks for your time

Have the same issue. Running 2.29. I just cant get the logger to keep up. Cluster is slow to scroll, editing a QSO is very, very slow. The Inet line is a 1G fiber both ways. So, I am kind of getting ready to bail, and try something different.

Hi all,
cluster contains a really large amount of checks, and sometime those checks are "heavy" as relies on your database for queries (even if most of the activities is made in memory).
I'll try to analyze specific info, can you in the meanwhile run a performance test in Log4OM and send me your results?
It's in the settings menu, one of the top items in the left column

So after much trying back and forth: Disabling VOACAP Prop. helps quite a lot as far as speed and snappiness. However, I rely heavily on VOACAP data, so I guess I'll be using Hamclock a little more. I also see a moment as the cluster is fed a new spot, the cluster screen hesitates a few seconds before you can scroll again.

The test below was performed with the following applications running: LOG4OM, WSJT, JTAlert, TightVNC, Chrome browser, Firefox Thunderbird Email client.

I have currently switched to another logbook for the time being until this can be resolved. Log4OM is not usable for me in its current state.
And as I said VOACAP is never ever activated on my side or this becomes a nightmare.

Hi Daniele and all,

Wondering if others still have the issue.
Unfortunately I still have, it is impossible to run a contest, when I need to be fast and Log4OM is freezing 10 seconds on each call it is not workable.

Also the CW window makes Log4OM very very slow it does not matter whether I am connected to Winkeyer or through TCI, for both it is awfully slow.

Between 8 to 15 seconds to edit a contact until the window opens up.

If anyone has been able to make Log4OM faster could you please give me some hints ?

Thanks

Hello
Even though it has provisions for it, L4OM is not a contest logging program
There are several out there, which will export to adif, and you can then import easily into L4OM.

It is so noted in the U.G. as well.

N1MM+ does an excellent job for the high-rate-flow contests and can immediately feed the Q's into Log4OM via a UDP port.

Or, as noted, a manual export of an ADIF from N1MM+ and import into Log4OM works as well.

Hello,

I am not using it for contest !
But from Vietnam you get a LOT of calls and you reach easily 150 QSOs per hour and Log4OM does not keep up...
But it is not a contest though

Sometimes I do as I have no choice but after importing into Log4OM it requires a lot of manual work:

- Update some specific information (maybe my N1MM was not properly setup but did not have the grid as well as Owner callsign coming empty)
- Also have to update all awards afterwards (like DDFM for French department one by one and it takes 5/7 seconds to have the edit windows to open) so it can take a very long time.

Finally I am not a huge fan using multiple logbook programs and I have never seen such behavior with HRD or N1MM or Win-Test or Cloudlog.

But I like everything Log4OM does so it is just a matter of trying to optimize it, definitely when I see a slowdown I qrx, reset map cache, close, re-open and I am good to go for another 20/30 minutes until it slows down again.
