Question Slowness Probkup.

#1
Good Morning,

We upgraded our rogress to version 11 in Linux CentOS 7 environment.
Previously we had it installed on HP / UX (Unix) server.
We use Probkup to do Online Backup from our banks. Our backup script on UNIX took about 1.5 hours. Today in the Linux environment it doubled the time, being realized in 3 hours, doubling the time.
Is there any specific parameterization for this command within the CentOS 7 Linux environment so that the backup performance is the same as HP / UX (Unix)?
Below is the script that we run in the HP / UX (Unix) environment. We are using this same Script in Linux.

Best Regards,
Paulo César

You should add -Bp 100

That isn’t a magic “go faster” parameter but it will prevent the backup from flushing-B which is beneficial

In my opinion the most likely reason that your backup is slower is that you made a counter-productive change to your disk subsystem as part of your migration.

Thanks.
