Support and Feedback / Re: high CPU usage

« on: April 23, 2014, 13:08:59 »

Sorry, I mixed them up a little bit.

The cpu usage is solved with NOOP checked.

What I wanted to say, is that when NOOP is NOT checked, and I connect then disconnect from the server, the cpu usage will remain until I restart MC. I expected that when I hit disconnect, the ftp module to shut down.

As you said, the problem is caused most likely by a timing issue.

Thank you for your help!

Bingo!
With NOOP enabled, there is no high cpu usage.
But IMHO, there is something fishy with the ftp module (why does the cpu usage remain  - checked with processexplorer - even if I disconnect from the server - with noop disabled? ).

Thank you!

Sorry for the delay.
I'm not using the NOOP. I have just the "Use Passive Mode" checked, and not doing anything, just connecting to the server. After connecting, the cpu usage spikes, and will stay there even after disconnecting from the server. The only way to recover, is to close MC and start it again. The server software is - from its banner - Pure-FTPd [privsep] [TLS]

The ftp server is a public one, its address is ftp.astral.ro. Anonymous user and default port.
It could be, that the server configuration is weird in some way (I have tried another ftp server, which is not anonymous, and is behaving the same way. From its banner, it is FileZilla Server version 0.9.27 beta).

I have updated to MC v4.2 build 1672 but there is no change in this behaviour.

Thank you.

Hi!

I have tested the FTP module cpu usage in a clean vm installation, and I was able to reproduce it every time I tried to connect to a remote ftp site - quick connect/saved session, anonymous user, passive mode. I have tested with 2 different sites, with same results.

Thanks!

Hi, I'm back with good news.
I have tracked down the culprit.

I have TortoiseSVN installed, and the TSVNCache process was scanning the folder and causing the spike in cpu usage in MC.
When I excluded the folder from caching in TortoiseSVN, the cpu usage in MC stopped. Interesting, indeed.

But, as the original poster stated, there is - it seems - another issue with the FTP module.
Every time I open a FTP connection, MC will eat up 1 core, and even if I close the connection, the cpu usage will remain until I restart MC. This seems not to be related to TortoiseSVN or the AV(Comodo) as both of them were disabled.

I will try to reproduce the issue on a clean VM installation.

Processexplorer will show FSFTP.dll+0x27732 as the cpu hog, inside MC.

Sorry about hijacking this thread. I thought  that the two issues were related.

Thank you!

Thank you.
I will give it a try tomorrow, and come back hopefully with some results.

I don't say that is slow, it (MC) just eats up a full core from the cpu. It may be because of the av, but the cpu is eaten up by MC. Nor Windows Explorer, nor TotalCommander does experience this behavior.

Thanks for the "dbg fslog" hint, I'll try it - and not post back the log.

Btw, I'm using MC in commander style and displaying the standard columns.

Hi!
I have observed also high cpu usage when a MC pane is displaying a folder where another process is modifying a file - ex. Firefox is downloading a file; in this folder there are some 1500 files and about 100 subfolders. The high cpu usage continues until i change the displayed folder, or the download is finished.
I'm not sure that I can reproduce this every time, but I have observed this behavior many times.

Thanks.

Feature Requests and Suggestions / Re: What do YOU want to see in the next major version

« on: June 26, 2012, 16:14:32 »

Hi, and thank you for this great software.
For a while I'm trying to familiarize myself with it, but sometimes I miss a feature or two of my favorite file manager. Like:

- the possibility to easily create an empty text file with a specific name - like SHIFT+F4
- maybe I was too lazy, but with "File Search" I was not able to find a specific text within multiple binary files, or maybe this a problem with File Search and not MultiCommander

Most likely I will find more things that I wish where there, but I will come back and update the list.

Thank you very much.
