SFTP Over SSH 100% CPU

poil · 10-31-2010, 05:28 PM

Hi

When downloading a file on sftp over ssh, a core is used at 100%.
Working fine when downloading from a FTP (1% of acore)

*Edit*
Another Bug : When changing speed limit when transfering a file on sftp, flashfxp stop downloading (0kb/s). Need to stop DL, start it again. The speed limit is not taken.

Using
Flashfxp 4.0 Build 1492 RC2. - French
Windows 7 PRO x86_64 - French
CPU : Core 2 Duo T9500
Memory : 4 GB

Best Regards

Do you encounter 100% cpu usage just when speed limiting is active?

There was a bug reported a couple build ago where if the speed limiting was enabled during a SFTP transfer you would see 100% cpu usage. Could this be the same issue?

SFTP transfers will use as much cpu as needed to transfer the file at maximum speed, high speed local network transfers could theoretically require this much cpu.

When you enable speed limiting during a file transfer FlashFXP will slow down the transfer to reach the desired speed limit, if the change is quite dramatic FlashFXP may stop receiving data for up to 20 seconds to reach the set speed limit.
