High frequently reading profile ini´s causing high I/O and CPU Usage in SyncBackSE while in idle background

Post by keun3nucun3 » Mon Jun 10, 2019 1:40 pm

Hi !
I recently upgraded from Version 7 to 9.0.4.1.

SyncBacup is one of the Top5 CPU consuming prozesses in Windows Task manager (continious 0,75 - 1%) in Windows while in SyncbackSE is in backgroud.
All my profiles are driven by time (each hour etc.)

I traced the process and found that syncbackse.exe reads/write all of the profile inis more then once a SECOND !

I have 10 Profiles, so all inis will be read multiple times a second.
It reads also the inis of profiles which has been deactivated since month.
Tracefile shows me over 60 MB of IO for 1 Minute just for reading inits in backgroud. (no copy job running)

Can you confirm this as a bug ?

regads,
keun

@mickyj
Sorry for this, but i traced the wrong PID.
The bug seems NOT to be fixed in Version 9.0.5.0.

SyncBack is still reading RHistory.ini Files once per Second. Also in Background.
C:\Users\<User>\AppData\Local\2BrightSparks\SyncBack\[PROFILE]_RHistory.ini

Hi, this isn't a bug. It needs to know when the profile was last run to see if it needs to run again, and that information is in the INI file. Keep in mind that the value can change due to it being run in a schedule (so in another process), for example, so caching it is not so simple. We'll take a look to see if it can be optimized for the next release, but I cannot guarantee it's possible. Thanks

The good news is that we have managed to optimize this and it will be in the next release. Thanks
