AFP/SMB Directory Listings very slow in Finder

Same issue.

ML Server to Mountain Lion client. (latest updates)

VPN connects.

My Open Directory binds great!!

Webdav through an FTP Transfer program works great (Transmit app).

The FInder. No connections. No authentication. afp and smb does not work. They just don't load in the finder.

It's sad that these little FTP programs work....but using the Finder to access server files?? Kind of takes the fun out of Drag n Drop!

plus now I have to cater and teach people how to use an FTP program.

There is one flavor I like on computers...and that's VANILLA (now blue folders)!

I've tried all the fixes. The only thing that did it for me was to bypass the finder entirely and use MuCommander:

File browsing over the VPN Smb connection is lightning quick now. Downloads and uploads are still relatively slow, but at least I can navigate the remote directories with speed.

I installed Yosemite beta here and it they fixed it! I have a Windows 2008R2 (SMB2) hosted in a remote datacenter (40ms latency) that no previous fix mentioned here before gave me Windows like performance (including DAVE). Now it works just like my windows machines going to this Windows share.

This is the real fix for slow SMB1 or SMB2 connections under OSX 10.9 Mavericks:

Go to terminal and enter:

sudo sysctl -w net.inet.tcp.delayed_ack=0

Now test smb samba file access, browse directories. Really fast, right? 🙂

Now you have to make this command permanent, so it will be loaded after boot. For this, create a startup item in /Library/StartupItems.

You do not need a StartupItem to set net.inet.tcp.delayed_ack=0

Simply create/edit the file /etc/sysctl.conf and write

net.inet.tcp.delayed_ack=0

into it. After the next reboot you cat check with

sysctl net.inet.tcp.delayed_ack

if it is set to zero.

Thanks keithrondinelli, mucommander fastened my vpn server browsing remarkably.

Next problem I have is that the word documents I access on the server via mucommander open as read-only.

Any help on this?

Fantastic!

The slow browsing from my Windows Server Essentials 2012 is gone!

This does not work when using a fileshare from a NAS. Still very slow speeds. Tested Mavericks vs ML, ML is blazing fast compared. Hopefully Yosemite fixes this, I have still yet to update to Mavericks because of this one issue.

I struggled with a similar problem for hours. Opening a Samba network share in Finder took minutes before the files and directories were listed. Replacing the server name with it's IP address solved the issue for me.

This worked for me

I tried to delete the cache from the user library.. didn't solve (i wasn't in safe mode)
I then went to the settings -> Sharing... and it was taking time to load too...
So i disabled everything for sharing one by one for all user and then turned it off (unchecked the sharing service)

Afterwards everything was back to normal speed, folders would load rapidly..
So, then i went and reenabled sharing for smb and afp and for windows for multiple users.. and it's still fast.

Hope it helps
Good luck

All:

I've got this same issue on my MacBook Air running Snow Leopard (OS 10.6.8).

I tried almost all the fixes in this rather lengthy thread, including:

- The various smb.conf file edits, Samba config, etc. (whatever the heck that does...I did it...lol)

- Told Spotlight not to search in the VPN folders

- Installed both PathFinder and muCommander as alternatives to Finder

In the end, the native OS X Finder is STILL slower than snake snot, and none of the fixes really did anything.

However, I do find that both PathFinder and muCommander are about 10x faster than Finder. Both of them took about 8 seconds to list everything in one of my VPN directories that the native Finder took almost 80 seconds for.

So....anyway...that's what I'm finding. No idea what my browsing my particular VPN folders would do under Mavericks or Yosemite.

By the way, if one has a physical machine on your company's network and Remote Desktop is enabled on that machine, an alternative is to just connect to your VPN, then use the REALLY GOOD new version of Microsoft's Remote Desktop Connection (RDC) for OS X to connect to your company-issued workstation, and use it's native file browser. For years, I despised how impossible it was to ever get Remote Desktop in Windows to work well, but the new versions really seem to work....I even connect to my workstation on my Android tablet after VPN'ing in using Cisco Anyconnect...works great.

sudo sysctl -w net.inet.tcp.delayed_ack=0

The command above worked wonderfully. Too bad I have no clue as to what exactly it does.

Will I face any drawbacks by using this command?

None of the described workarounds worked for me 😟

Server: RHEL 6.6 (x86_64) using Samba4

Windows PCs (Win7, Win8, Win8.1) on the same network list folders with 10-30k files instantly

Macs (Maverics/Yosemite) do that in 3-30 minutes

These tweaks for Mac OSX did not help at all:

defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool true

sudo sysctl -w net.inet.tcp.delayed_ack=0

I have tested on another server, with newly created share:

Created a new folder in that share, and ran the script to create 10,000 files, when I connected from yosemite to that share, and browsed that folder with a bunch of files, it took 5 mintues to display a list of files.

Here is the script which I have used to create a bunch of files:

#! /bin/bash

for i in {00000..10000}

do

echo hello > "/Data/Share/File-${i}.txt"

done

Any other solutions available?

I had severe performance problems using Samba under Ubuntu 10. After upgrading to Samba 3.6.x which supports SMB2...

sudo add-apt-repository ppa:automation/ppa
sudo apt-get update
sudo apt-get upgrade samba

and making sure SMB2 is put to use ....

max protocol = SMB2

(in [global] section of /etc/samba/smb.conf)

everything works fine.

I was reluctant to upgrade to Mavericks for a while but I had to because on one application that would install only on it. I struggled with this issue for a while and was thinking in rolling back. But after adding those values to the registry it is working much better. I am using Server 2012. I would definitely your post as the answer for those who are comfortable with working with registry. Thanks.
