#953 Synch orders of magnitude slower than before

[Mike Cowlishaw]

Hi, I have used GCSM for many years without problems. However for the last couple of releases it has suddenly become exceedingly slow. For example, after 5 minutes it is Matching contact 76 of 971 .. so it looks as though it will take hours to complete -- whereas before it took around two minutes.

Any ideas what the problem might be/what has changed?

Thanks!

Same problem to me. More than a day for 3700 contacts. It dow not reach the end....

Same problem...exceedingly slow... only 425 contacts in 1 hour!

Now it's back to full speed.
Have just updated Windows to latest versions which maybe is the answer?
2022-12 Cumulative Update for Windows 11 Version 22H2 for x64-based Systems (KB5021255)
2022-12 Cumulative Update for .NET Framework 3.5 and 4.8.1 for Windows 11, version 22H2 for x64 (KB5020880)
2022-12 .NET Core 3.1.32 Security Update for x64 Client (KB5021953)

W10 last update .NET last update does not help.
Anyone a clue what is the cause of slow process. 3700 contacts lasts for more than 12 hours.
Formerly it ran within 1/2 hour. Why why why?
In this manner this SW is not usefull any longer.
Removing sync of photo's makes a big difference! That is the solution.
