does anyone have any idea why my FTP speeds are HORRIBLY slow?!
like, 50 to 120k/sec TOPS... ps3 is wireless, but they shouldn't be THAT bad?!?

Wireless is crap on the PS3 because it has a bluetooth transmitter sat right next to it, or you have a wireless or something next to it running at 2.5 ghz, so before you look to deep into your setting remove phones, chargers, bluetooth head sets away from your router and PS3.
Mine is crap as well, wireless wise bud,like many others and it could be lots of things, like router issues, and the way windows works with QOS, stinks.
Unless you change your network settings on your wireless card to work at full speed all the time, having priority over all your network, to one connection like your PS3, then your wasting your time trying to make it run fast as it says on the tin, because windows and your router is trying to spread the LAN load across all your computers.
Use a cross over cable bud, so much faster than any other way. In some rear cases you can get 800 MBit /sec maybe the full 1000 MBit /sec using cat6 crossover cable. and of course having a 1000 MBit Ethernet card in your PC/laptop like most do now days.

Even with a 30cm cat6 crossover cable direct from the ps3 to the pc you'll never get close to 800Mbit/s (100MB/s) you'll tap out in around the 25MB/s (200Mbit/s) mark, maybe a little higher maybe a little lower, normal hard drives just dont work that fast, and the ps3's is particularly slow no matter what type of drive you have inside it.
As dave says though it's probably a wireless signal issue why your ftp speeds are so slow, i'd change the wireless channel if there are a few other wireless networks detected by the computer always by at least 5 though (the different channels overlap) so try 1 or 11+ instead of the default 6. other than that it's really either move the two closer together or switch to cable sadly
Here is OpenPS3FTP v1.2 for the first post.
Version 1.2 Changelog:
- Added XMB exit event handling (thanks facanferff)
- Cleaned up and shortened some code
- Fixed up the last modified date in directory listings
- Added an option to disable the login checking (at compile time)
- Fixed a small bug in passive mode which made the transfer fail
i hope that new release is more stable.
it locks on me every 30 mins.
does this application allow the use of more than one channel in the pc ftp applications? that would be awsome...

Barry you're absolutely wrong, going on my last post, with the formula I used when I said 1000 MBit /sec,and 800Mbit/s. Sorry that was misleading and would be seen as incorrect, seeing people read in Megabytes and Gigabytes.
I do agree with you Barry about the drive maybe not being as fast as we would like it. but it is in no way slow running 3 Gb/s, so unlikely the drive could hinder the speed of the network transfer in anyway, unless it was seriously fragmented, or the drive needs replacing.
I’ll try to explain my reason for saying this Barry, so forgive me if I am being a complete ass and totally getting this all wrong, but I have to disagree with your logic on your post. I have a Western Digital Caviar Blue WD5000AAKS 500GB 7200 RPM 16MB Cache SATA 3.0Gb/s in my ps3.
So I have a drive with 16MB of cache capable of transferring 3 Gb/s across my 64bit powerpc bus, on a system thats only running a small simple Linux Kernel,a small ftp app,using its built in 1000 BASE-T full duplex network card, then connecting to my 3.6 quad core PC with like wise speed of drives, a 1000 BASE-T full duplex network card, but changing some of the PC card settings, and finally a extremely well made cat6 none crossed over cable, because you don't need it on a 1000 BASE-T cat6 link. And then tested with a penta scanner I own myself.
Anyway I was having to move a 30 gig movie back to my pc because I was formating the drive, before beta testing some homebrew, and knowing how long it could take, so I knew I'd have to change and set the connection settings to give me the full use of the 1000 BASE-T transfer speeds.
I set i,t to only have one ftp connection tho, because the way I thought was if you have more than one connection reading and writing at the same time, it slows things down with buffering, waiting. Regardless of how ever short the wait maybe, its still a bottle neck, I thought.
After letting it settle down and level out, with transferring that 30 gig file for about 90 seconds it settled at 63 MB/s
The formula I used. With both the network cards at both ends being Gigabit Ethernet set to frames at a rate of a gigabit per second,.
So 1 gigabit (Gbit/s, Gb/s, or Gbps ) = 1,000,000,000 bits per second.
Or a 1,000 megabits per second or
Or if you like bytes , it = 125,000,000 bytes per second.
So I said “In some rear cases you can get 800 megabits per second , that = 100 megabytes per second, and I have been getting 63 megabytes per second across my link.

ok first off your hard drive is nowhere near capable of reading 3Gb/s thats the theoretical max of sata, your hard drive doesn't actually read anywhere near that speed, try and remember the hard disk is the slowest part of a pc as it's the only real component containing moving parts (with the exception of SSD's btw).
second of all it doesn't matter what kind of drive you have in your PS3 you'll see no increase in speed as it's limited by the firmware (even with an SSD you'll see no speed increase).
As for your 63MB/s speed not only is it not "In some rear cases you can get 800 MBit /sec maybe the full 1000 MBit /sec" but you'll find its probably due to a mistake in the ftp apps calculation try transfer 1 640MB file (a dvdrip of a movie would do) and I guarantee it takes longer than 10-11 secs.
And stop calling me absolutely wrong all the time lol, I put both in my answer in Mb/s and MB/s (I included both hoping you'd see that even suggesting a 100MB/s transfer speed is ridiculous, what with most conventional hard disks being unable to write at that speed!)

I'm sorry Barry but I still don't understand your logic, you say "the hard drive is nowhere near capable of reading 3Gb/s". The spec of the drive, says it can. So the native transfer rate of 3.0 Gbit/s, with 8b/10b encoding buffered in 16megs of on board ram, will give the maximum uncoded transfer rate of 2.4 Gbit/s = 300 MB/s. The theoretical burst throughput of SATA 3.0 Gbit/s is roughly triple that of the ps3's 1 Gbit/s = 100 MB/s network card.
Don't forget Barry, the new 3.0 Gbit/s SATA devices we upgraded, in our PS3's are effectively the top end of the SATA drives now, or the bottom end of the new 6 Gbit/s drives = 600 MB/s Barry, wow thats fast. SATA also has NCQ that improves the performance.
So I really don't think the hard drive would ever come into the equation of FTP speeds, because it's 3 times as fast as the network card. I forgot one more thing,because I did this ages ago, was I created my own drives partition's and changed the starting sector, before installing win7, because it gives me 70MB/s , all day long. So my 63MB/s is true, because thats what I get.

no the sata connector on the end of your drive is capable of 3Gb/s thats not the actual throughput of the read write heads!, that's irrelevant when you look at the read write speeds of a mechanical drive. you're really not getting this are you, that hard drive will never fill a 3Gb/s pipe.
"Average read and write results of 74.5MB/sec and 48.1MB/sec place the 500GB Caviar Blue near the bottom of our benchmark table" -- Taken from pcpro.co.uk/reviews/hard-disks/252141/western-digital-caviar-blue-500gb
And those results aren't bad for a mechanical hard disc, the things were designed in the 80's and haven't really changed since. Your 63MB/s transfer speed might be right i'm not argueing i'm just saying it's nowhere near 100MB/s or the equivelent 800Mbit speeds you originally stated
