Flash FXP Slows Down To Almost a Halt on Large File Transfers. Also Hogs CPU

[DeMiNe0]

When i use the latest version of flashfxp to upload a 600mg file on a very fast FTP, after about 30 seconds flash fxp starts to take around 95% cpu and also starts to slow down ALOT. At one point it was lagging sop bad that it took 5 minutes just to draw the flashfxp gui.

I am on a fresh install of Windows XP sp2 and i also tryed uploading to a few different FTP's.

It does this on 2 of my computers.

It works fine if i upload using cuteftp.

* FlashFXP v3.0.2 build 1045, registered
* OS: WinXP SP2.
* Running behind NAT/router: Yes Netgear WGT624
* Running firewall: Yes, ZoneAlarm Security Suit v5.5.062.004
* Running Antivirus: Yes, Kaspersky
* Network: CABLE

* FTP server(s) : ProFTPD, PureFTPd, Any others i have tryed.
FTP Log:
I cannot get an ftp log since it freeze me to the point where i have to ctrl alt del and kill the process.

Basicly, it will upload. It will start at like 80kb/s and stay they way for a little while. Then all of a sudden it will rocket up to 300kb/s. I don't think my connection can even go that high. I also tryed putting a limit on it from the flashFXP options, and it still seemed to go higher then the flash fxp limit. Went to about 300kb/s again and froze. It does this on all 3 of my computers running Windows XP SP2.

do those other computers use ZoneAlarm too?
if so, try to temporary uninstall(disabling is not enough) it and see if that makes any difference.

[DeMiNe0]

I just tryed that, and it did not seem to work.

[MxxCon]

it's obvious, but have you tried redownloading flashfxp from http://www.flashfxp.com/download.php and installing it to a new dir?
just to eliminate the possibility that your copy is somehow got corrupted.

[DeMiNe0]

Yes, i tryed this a few times on 2 computers. No luck. It also did this with older version of flash fxp.

[DeMiNe0]

so is there any other ideas?

[MxxCon]

is it only when you upload large files?
or small files too?
what about download?
when you say ffxp starts to take up 95% of cpu, did you confirm it with task manager that flashfxp.exe process is doing this, or just assumed becuase system was slow?
have you tried disabling your antivirus?
what other software you have running when that happen?

[DeMiNe0]

Only happens with large files.
I confirmed CPU useage with Task Manager.
My download is fine.
I tryed disableing and uninstalling.
No other software running.

ZoneAlarm has been known to slow down and makes internet applications work harder. ZoneAlarm may be causing your unusually high cpu usage with FlashFXP during upload.

Disabling ZoneAlarm isn't a good test, Either test FlashFXP on a machine without ZoneAlarm or uninstall ZoneAlarm.

[DeMiNe0]

I have tested it on a machine that has no zone alarm on it at all. I think it may be a problem with my ISP and flashfxp somehow. I tryed it on a regular windows 2000 machine and it did the same. I have no clue how it can be related to my ISP, but that seems to be the only explainable way.

[MxxCon]

don't see any way for an ISP to affect cpu usage on your local machine

[Shark]

I am not going to ask what or where you are downloading/from...

But, have you tried from a stable public server ? To at least test if you are getting constant speeds their?

Also is it possible to try without the router ? or is that how the net goes...

Do you have any specific settings in FFXP for your router?

I have the same exact problem when i ftp files from xbox to pc, the small files are fine along with sending them from pc to xbox, but the large files start out fast and become very slow taking up 100 percent of my cpu (1.7ghz p4 with 785ram). Ocassionally there it disconnects when switching to transfer the next file after sending a large file (by large i mean 100meg plus)

Also i cant seem to figure out how to make the flashfxp open with the local browser on automatically, is this possible?

edit: also flashfxp randomly restarts my computer and when this happens the operating system gets corrupted (i know it isnt a virus because i have scanned numerous times and have had it happen to a fresh install of everything)

[chuck_li_2]

I also met this problem when I download larger file. However, upload is no such problem.

I didn't install firewall and Antivirus software on my interernal computer. And I try to download 300MB file from my another computer which is in same network area, but CPU usage still reachs 100% and flashfxp looks like hang up. However, transfer still go on.

[MxxCon]

chuck_li and zaogm, your questions will not be answered here.
your problems are completly different from the original poster.
please do not hijack this thread.
if you need support, feel free to make new thread with all the details.

[DeMiNe0]

OK,
I got a new laptop with windows xp sp2 on it. I brought it to my girlfriends house, put flashfxp on it and tryed to upload a 38 meg file. Te same exact thing happens. No router, different isp, and a totaly different computer.

If this is not fixed. I would like the money i payed for my licence back, since flashfxp won't serve a purpose to me.

[MxxCon]

REDOWNLOAD and reinstall flashfxp.
do not use your existing copy.
either you are doing something wrong or lieing.
this is the 1st time in 7years of using flashfxp that i hear of anybody who has such problem on totally different computers with different configurations.

guys, I am having the same problem, slow transfers on large files, and GUI freezes after about 10 seconds and ther is high cpu usage, I have also tried cuteftp and it's the same thing.I am using the demo version of fxp, I am using XP SP2 with
zone alarm.

I am have a connection between my P.C and Xbox
I am trying to look for a common problem, and fingures are pointing to zone alarm or XP SP2, however in my previous installation of WinXp (without sp2) I had no problems at all.
I have also found uninstalling Zone Alarm is only half the
problem, there is also an internet monitor with zone alarm and
at times it tends to stay put.:confused: :confused: :confused:

A quick thought, how sensative is fxp to time stamps on files,
could it cause the gui to freeze if they don't match. Xbox does loose it's clock after about 24 hours.:)

If i fix it, I'll put up another post and I'll also be watching.

[******thecat]

I fixed it, just uninstall Zone Alarm and make sure the "True Vector monitor" is also uninstalled and then
restart your machine, I'm now getting up to 15meg a second
to the Xbox:D :D :D :D

[Chrysalis]

I get 100% cpu on lan transfers but that isnt flashfxp fault its down to me using a cheap LAN card, the speeds are around 80mbit over LAN but it maxes my cpu, but will do this over all protocols.

[DeMiNe0]

That seemed to of fix it. Thanks Cat.

When i took zonealarm off the last time, the True Vector monitor was never removed.

I switched to sygate personal firewall and that works just fine.

If a file is greater than around 90Kbps, the downloading just decreases to zero and halts. If I re-attempt this several times, I eventually download the file but have to repeat the process again. This occured on another XP machine of mine which didn't have ZoneAlarm or Karspersky. The only choice was to reboot. I don't see why I have to reboot to get the software to work.

Is this a known issue, does anyone from the fxp staff reply here. This is very irritating as I have to resort to other FTP programs for "larger" files.

Many thanks.

P.S. Tried uninstalling firewall and anti-virus but no luck and the CPU isn't a problem, just the fact I can't download.

This is not a problem we are aware of.

Do you encounter this problem with all ftp servers or just some?

[janusz]

I find this problem with all servers but if the file is large (100Mb+) then it's ok, just seems to happen to files between the size of 100Kb and 100Mb roughly. I can sometimes get to around 180Kb and then it just freezes again.

The majority of the problems though come when I use the servers of www.fasthosts.co.uk but as far as I can see from their support forums, no one else is having the problem.

I deleted (clean) zonealarm and avg, took off IIS and abpout 75% of the programs on the system but still having the problemo! I think a re-format is in order but not sure why I should go to these lengths... can't really complain as fxp is by far the best ftp utility I've used :D
