sFTPDrive is very slow

I also get a performance hit. It takes 6-9 to display directory content, drilling down and backing out. And get this, it does not matter if it is an SFTPdrive connection, or another windows mapped drive. As long as SFTPdrive connection is up, performance takes a hit. Local drives, e,g, C:\ have normal performance. Many users have abandoned it and stayed with Samba which we are trying to decommission. Still waiting, after a few months, on a solution.
Opening "My Computer" takes anywhere from 9 sec to several minutes for some users, but *only* when there is an SFTPdrive mounted.

You need to do SOMETHING about the speed!

I get it browsing, and even when not browsing an SFTPdrive mapped drive. Just opening My Computer takes 10 seconds. Each non-local drive has the same delay whenever navigating down/up another directory, AND only when there is an SFTPdrive connection open.
If I disconnect, then speed is back to normal on those other directories.

I just now came to this forum hoping for a quick fix for the poor performance. I would absolutely love to purchase sFTPDrive, but right now WebDrive outperforms it by a huge margin. My intended usage is very simple and modest...basically just open/save text files and spreadsheets off my linux "share". However, with sFTPDrive, these operations on even the smallest files cause "Not Responding" delays.

Even basic browsing is slow. For grins, I tried to use Windows Photo Gallery to open up a series of directories with images in them and it was totally unusable under sFTPDrive. With the other product it works just fine. On a linux machine using sshfs, browsing performance is so good that I am nearly unaware it's a remote share!

I just downloaded the trial version of WebDrive. It did not have the performance hit of SFTPdrive.
I don't like it as much for our purposes, but my hand may be forced by the user community. It is also on par price-wise for a 50 pack. The only difference being the limited free version upgrade timeframes.

When will the next version be ready for testing? Next month? or next year?

Hi

Not sure about your specific speed issues but I discovered that Winzip was causing my slowdowns when using sFTPDrive. I found that when the Explorer Enhancements portion of Winzip is enabled (the extra menus you get when you right click) then I had major delays and pauses when copying, pasting, etc. I turned off the Explorer Enhancements and voila. No more delays. sFTPDrive is much faster.

I think that Winzip must be requesting file header information so a portion of the file is being downloaded before the menu even shows up. I am using Winzip 11.1. Maybe this is different for other versions.

Hope that helps you.

Jeff, I'm not sure all those "speedups" from ExpanDrive are going to help.
Frankly, I get the same poor performance on ExpanDrive that these guys are reporting here. And that hasn't changed since version 1.0.

1.7.9 sftpdrive
~1.7mb/s max speed
~1.6mb/s ftp
~1.4mb/s webdav over ssl
~800kb/s WinSCP
~500kb/s sftpdrive

all transfers right after each other same server/client
no significant cpu or memory load on either

whats the problem?!

sftpdrives first impression is great ilove to manage my remote files like local ones but i need more performance

What should performance typically be like? Between two dual-processor machines and a gigabit network, when I use rsync over ssh I get 9-15 megabytes per second transfer rate. With ExpanDrive I only see 1-3 megabytes per second. I'm typically transferring big files, 10MB-10GB.

I've taken to transferring bigger files via scp or rsync over ssh like I was before.

For small files, ExpanDrive rocks!

I just installed the latest, 1.7.9, and the performance for listing a directory is either 100 times slower than the year-old version I was using, or there's an endless loop bug. After 5 minutes it still hasn't come back yet. This used to be great software. What's going on? I'm a licensed user.

I have the same problems (osx leopard - expandrive 1.3.3b1). it turns out that the software is unusable for me. everything went slow. opening dirs, uploading, downloading, deleting, saving from textmate. everything taking ages :( and runs much much faster over a ftp client (transmit). I tried everything, sftp/ftp, different servers, computers, big dirs/files / small dirs/files but all the same -> very slow :(

i think its more a problem of the response time, maybe. one big file uploads faster than 1000 small files with the same overall size. but dont know really..

I just tried MacFUSE 2.0 + sshfs and it works very nice on a Gigabit LAN. Still not anything above 10MB/s, but CPU usage is very reasonable (only 10-20% on a 2.8GHz Core 2). I doubt its caching is better than ExpanDrive's, but on a LAN where latency is low this shouldn't be a problem.

I'm a user which does pretty heavy word processing and spreadsheet-work on an sFTPDrive, over a 8Mbit cable modem connection. I'm quite positive about this product.

Full disclosure: not related to the company in any way, just a satisfied customer.

i'm a licensed user on windows xp....sometimes sftp works great, then for seemingly no reason it slows to a crawl and takes basically my whole computer with it(because i can't operate windows explorer).

what's wrong? it seems like requesting the contents of a directory via ssh shouldnt take 5 minutes.

this product would be 10x better if this didnt happen.
