FTP from shell = high CPU usage
 

Hello,

I registered on the forum to report a couple of problems I've been having with Powerarchiver 2012 Professional.

I am glad to see that the first problem has already been taken care of, namely, the hanging of PASTARTER.EXE introduced with 13.01.03 - fixed in 13.01.04.

The second problem is high CPU usage when using "FTP It..." shell extension. I made a few PA backup scripts which make encrypted 7z archives, copy these archives to two other locations (nice feature), and then FTP these archives to a remote FTP server (another nice feature). All is well, with regard to CPU usage, when PABackup.exe is doing the FTP file transfer, but when I right-click a file and click an FTP profile the CPU usage of POWERARC.EXE doing the file transfer goes way up - maxing out a core if I set process affinity to just one core. I cannot tell you when this problem started since I have not been using this feature for long, and I only noticed this summer due to high revving CPU fan.

Hopefuly this is something that can be fixed in a future release.

Best regards,

iDunk

thanks a lot, we will try to reproduce it and let you know if we have any questions.

Does the actual FTP upload finish?

Yes, the upload always finishes ok. Process Explorer shows a high cycles delta at offset 0x875470, if that is of any help.

System info: Windows 7 Pro, Core i5 750, 8GB RAM, latest NIC driver
Antivirus is Kaspersky Internet Security 2013 (happened also with 2012). I think I can exclude the antivirus/firewall as the culprit since all Conexware programs are in the trusted group and yet pabackup.exe and powerarc.exe behave differenty doing FTP.

ok, sounds good... we will let you know when our testing goes though it... if we can reproduce it, it will probably be fixed in next release (few weeks).

I was able to reproduce this and have logged it in.
thanks for the detailed report!

Hi,

I'm a new user of PowerArchiver and I'm experiencing this too however I'm not activating any extensions - I performed a clean install on two computers, and both frequently go to 50 - 51% CPU usage. Windows 8 on both machines.

Any suggestions?

Thanks.

disable pa starter from starting, it is issue that was solved in last release. Ctrl-alt-del and kill pastarter.exe process.

pastarter was not compatible with win8 so we had to rewrite it completely. You can disable its startup in Options> Configuration> PA Queue.

Thanks, I'll give that a shot!

High CPU usage with FTPit still present in 13.03.01 and 13.03.02 :(

thank you, we got stuck on 2013 for a while, but now we are good to go.
