Very Slow VPN

I have a pretty basic server setup. The same setup I've done many times before (although all the others have been on 10.5). Basically the server is also the router. VPN uses the high end of the IP range, DHCP uses the middle. The firewall is set up to give full access to the LAN including VPN connection. And public access is limited. I did map all the important ports, 1701, 4500, 500, GRE... (i forget the full list for L2TP but they're all checked). Oh yeah, I'm talking about L2TP. So I can connect to my VPN fine, but the speed is horribly slow. The most dramatic way to illustrate this is connecting to my server's external IP (i'm in another town currently) in Safari to load the default OS X page. It loads basically instantly. Then load the same page using my server's internal IP address, while connected to the VPN. It loads, but it takes about a full minute to full load. This is kind of an issue because I was planning on running the iCal servers over the VPN from user's iPhones and iPads. I can't think of anything else that could possibly be slowing this down. It's like my VPN pipe has been top-killed. Yippee for topical humor. Any suggestions?

AFP Directory Listings via VPN very slow in Finder

Hello all!
I recently exchanged my existing Apple iMac Core2Duo (with Mac OS X 10.6.8) to a brand new iMac 27" i7 (10.9.4). Besinde to this new iMac I´m using a MacBook Pro 15" (with 10.6.8). WLAN/Airport is turned off; only Ethernet / LAN is used.
My problem right now is: since the upgrade to OS X Mavericks we are experiencing server problems, browsing AFP shares on remote servers (VPN). The Directory Listing is very slow an can take up to 30 minutes for large listings. I can't browse network folders with Finder because it's too slow. It takes forever just list all the subfolders. If I try to transfer or open a file, everything is fine and I can do it at the right speed.
Here's the setup
2 networks are connected thanks to a VPN connection.
All clients, in all connected networks can communicate to a common fileserver (MacPro with OS X 10.6.8 SnowLeopard Server) in Network A
Firewall is not an issue between those networks
The clients authenticate via OpenDirectory and Kerberos to the fileserver
So the problems occur if i want to connect a client on network B to the server on network A. Connection, authentication, ... all good. Even the performance over the VPN, to tranfer files is OK. But browsing subfolders is catastrophic. I used AFP , results are the same. I also made tests on older clients, to see if the fileserver is the problem. 10.6 and 10.8 clients can browse normally, speed is OK.
So my question: What can I do to accelerate the browsing of my AFP/SMB shares for all my Mavericks clients? What can I do to speed up the Directory Listing? And yes: i know about solutions like PathFinder, TotalFinder, .... but i'm more interested in a native solution to this problem.
Thx!!
OS X Mavericks (10.9.4), 10.6.8 Server

This has been a major issue in Mavericks all along. SMB has been a total disaster for anyone who works with MACs on a corporate network, causing admins night terrors, anxiety disorders, and general sadness. 10.9.4 + some server side fixes (smbcreditsmax and smbcreditsmin) fixed many of the issues, but the slow finder listings over VPN connections is still unusable. the only workarounds i know of are:
- switch to windows
- downgrade to mountian lion
- use FTP or webDav protocols
- use a 3rd party finder replacement: mucommander (clunky additional app but works!)
I will be testing Yosemite beta this weekend, i have heard reports that some of this nonsense is fixed.

File transfer very slow with a SSTP VPN

I have a serer in the office and I connect from my house through a SSTP VPN. In my home computer (client) I add a new network folder, this networkf folder is in the server, that has a shared folder. I can transfer files, but is very slow.
For example, to transfer a folder that contain about 20 files, and in total are 11MB, it takes about 3 minutes. The server has a upload bandwidth of 890kbps. With teamviewer VPN takes about 1minute with 55 seconds.
The problema with the SSTP is that the transfer speed is not stable, bteween 0-200kbps. The problema is that when has to transfer a file, always the same, the speed drop to 0bytes/s and in this state is about 1-15 seconds and continue the transfer. Why?
So the total time at the end it's much more than the time that I need if the connection was stable and used all the bandwith. How I say, teamviewer VPN takes about 1:55 inteado of the 3:00 of SSTP.
Thank so much.

Hi ComptonAlvaro,
Please check if we have other program is connecting the Internet when we use the SSTP.
Additionally, we could contact the ISP to check the stability of network.
Regarding the slow SSTP performance issue, we could refer to the following thread similar to this issue.
http://social.technet.microsoft.com/Forums/en-US/8e8e4220-af25-4627-bed2-47db8c04d318/sstp-and-slow-transfer?forum=winserverNIS
Please take the following steps to fix this issue:
1. Add new registry key and value “ TcpAckFrequency=1 ” for all NICs on VPN server, so that we can reduce ACK delay.
2. Disable Windows 2008 SNP feature, and restart VPN server
3. Disable TCP Checksum offloading on VPN server
Hope it will be helpful.

Mac with vpn tracker software running very slow

Hello,
I leave in Seattle and I use a Mac G5 running vpn tracker software tunneling into a Microsoft corporate network in San Jose, CA. My mac is plugged into a router and it is very very slow. I also have a PC with vpn tracker software which is running wireless and it is fast. Any ideas on what I need to do to make the Mac run faster. Could this be issues with my clients network? Should my Mac G5 be running wireless in order to get it running faster? Any advice would be appreciated.
Stephen

I have the same problem. It is really, really slow. Does Windows work better than the Mac in this respect?

Very slow Windows domain login over IPSec VPN

Hi
I'm experiencing very slow Windows domain logins over an IPSec VPN connection. The AD is in Site 1, some users are in Site 2. Two Cisco ASA firewalls connect both sites by an IPSec VPN over the Internet.
I made some registery changes on the Windows XP client on site2 to let Kerberos communicate over TCP instead of UDP. Still the logins take extremely long (45 minutes). Profiles are very small, so there had to be a problem with Kerberos, MTU sizes or somethin like that. I already changed the clients MTU settings to 1000 byes, but login is still very slow. I made some sniffer logs...
Does anybody know what the problem can be ?
Regards
Remco

Hi Remco,
The most common issue with slowness over VPN is going to be fragementation. In general below are the recommendations to avoid fragmentation
1. For TCP traffic, use "ip tcp adjust-mss 1360" on the Internal LAN Interface on the Router. If you are using GRE then configure "ip mtu 1400" under the Tunnel Interface.
If you are not using GRE then the value of "ip tcp adjust-mss" depends on the type of transform-set being used E.g. AES\3DES etc, so you can increase the value of TCP adjust command from 1360 to a higher value. Though I will start from 1360 first for testing.
Also take a look at the below article for MTU Issues

Data Services Designer - Very Slow on VPN

Hello,
Any idea why Data Services Designer is very slow and many a times goes into Not Responding state. I'm using this client tool to connect to the Data Services Repository + Servers via VPN.
It takes few minutes to load the jobs or to save the changes. Some times hangs.
Wanted to know if anyone is facing similar issues, and any workaround/setup changes to eliminate these delays...
Regards,
Madan
Edited by: Madan Mohan Reddy Zollu on Mar 12, 2010 9:24 AM

Data Services Designer is communicating with the repo (to store/retrieve objects) and the jobserver (to execute jobs and get status/log files) so if there is a slow network connection, response time in the Designer could become problematic.
One way to solve this is use CITRIX or terminal services to have your Designer close to the database and only screens are send over the slow connection. In the Windows installation guide there is a chapter that documents how to setupDesigner in a (multi-user) Citrix environment.

WatchGuard S2S VPN very slow

Hi guys,
I have created a site to site VPN between my WatchGuard XTM firewall and MS Azure static gateway. The VPN connects without any issues, but I noticed the file transfer speeds to my servers (via SMB) are very slow. Most of the time it peaks at 350KB/s, sometimes
it hovers around 70KB/s. I have 200Mbps fibre link that is not saturated at all.
sometimes it reaches 3-5MB/s, but it is rare and random.
I'm located in Sydney Australia, the Virtual network is in the UK. I tried to test the Netherlands and Sydney data centres, same exact problem, very poor performance.
Anyone having similar issues with S2S VPNs?
Thanks,
Ib

Hello Code_Jax,
1. Have you created the Azure resources in the same data center region?
2. Is the region that you have chosen close to your On-premise network?
I suggest that you change the region where you have deployed your Azure Resources and check if you get the same Performance.
I also suggest that you use Netmon to and analyze network traffic. You can follow the link below to download Netmon:

Firewall/VPN Model-SG300 Cyberguard after configuration internet working very slow....please help me...

HI FRIENDS,
i have one firewall model number sg300 i configured each and everything
but after configuration internet working very slow.if i want to open any website it is taking 5 min .i connected
my lease ling directly in this device.
please help me....
Thanks,
Madhukar

Hi Madhukar,
It seems that it is not a hyper-v issue .
For troubleshooting this please use your computer to access internet directly (without firewall ).
If it works well , you may go over the configuration of the firewall .
Also you can contact the hardware vendor .

New T530 very slow

I just bought a new T530 and it is running very slow. A little background. I am not too tech savvy and use a T520, T420 (both of which I bought used) and this new T530. All are i5, 4 GB RAM and because they are work machines I have whole disc encryption, VPN software and some other required software. All have regular HDD as spped hasn't been an issue for me. Of the 3 my T420 is by far the fastest. The T520 is slower but acceptable but the brand new T530 is very slow. I use Chrome for my personal browser on all machines but for work stuff it is Internet Explorer 8 and Microsoft Outlook for e-mail. I have searched posts here and deleted some of the Lenovo and Thinkpad preloaded software, performed updates, stiopped some start-up programs in msconfig and made sure it is set to maximum performance. Even when I have no programs running the processor is running in the background constantly. It is slow to boot up and slow to open any programs. Any advice would be greatly appreciated. I am going to try and use the 530 and 420 side by side to compare what processes and services are running to see what is different. Any other suggestions would be very helpful.

Slow VPN Connection

I have had Windows Server 2012 Essentials setup and running now for over 12 months and have been using the Remote Web Access to share certain files with our employees. When using the RWA you can download files in seconds without issue.
I recently wanted to setup a VPN connection to the server so that I could remote manage the server if needed rather than have to go to the office all the time. I added the role on the server, forwarded port 1723 as needed whilst at the office. Then at home
created a VPN connection on my Windows 7 PC. The VPN connects very quickly without issue but when trying to do anything the lag is very slow. On the laptop I used the cmd prompt so I could ping the server to see what was going on, i get a lot of time outs
when doing anything, even when trying to just open a folder that is also shared by RWA and opens without issue.
If i use Remote Desktop it just constantly times out and closes, so cant do anything.
It appears this is just a VPN issue as RWA works perfectly. Any ideas as to what would cause this?

Sqlsrv very slow over network

I'm using sqlsrv (php_pdo_sqlsrv_55_ts.dll and php_sqlsrv_55_ts.dll) in PHP (5.5.12, CLI version on Windows 8.1) to connect to a SQL Server 2012 over a VPN tunnel. But the transfer rate for large result sets is very slow.
Testing SSMS on the same PC over the same VPN tunnel for this query (query is just for testing purposes, I also tried other queries with large data sets and all showed the same performance issues):
    SELECT *
    FROM [Data].[dbo].[Logins]
    WHERE date >= '2014-01-27 00:00:00.000' AND date < '2014-01-29 00:00:00.000'
returns about 100,000 rows in 4 seconds. Checking the transfer rate on my firewall/VPN shows 2,500 KB/s (on a 100mbit network) while the query is running.
Using PHP:
    sqlsrv_configure('ClientBufferMaxKBSize', 1024*1024);
    $dbconnect = "SERVER\\HERE";
    $dbconinfo = array("UID" => "user", "PWD" => "pass", "Database" => "Data")
    $conn = sqlsrv_connect( $dbconnect, $dbconinfo);
    $sql = "
    SELECT *
    FROM [dbo].[Logins]
    WHERE date >= '2014-01-27 00:00:00.000' AND date < '2014-01-29 00:00:00.000'
    $options = array();
    $options["Scrollable"] = SQLSRV_CURSOR_CLIENT_BUFFERED;
    $options["QueryTimeout"] = 30000;
    $stmt = sqlsrv_query( $conn, $sql, array(), $options);
runs 40 seconds and the firewall/VPN shows less than 150 KB/s while the query is running. Task-Manager shows around 5% CPU load for the script.
I used SQLSRV_CURSOR_CLIENT_BUFFERED just for testing, because it reads the result in its own buffer without any further PHP code. Fetching each set of data without buffering is just a little bit slower (around 45 seconds).
I also tried a PDO version which lead to the same result.
ConnectionPooling 0 or 1 didn't make any difference either.
Changing server name to DNS vs. IP adress also made no difference.
LogSubsystems -1 and LogSeverity -1 did not show any issues or anything helpful at all.
I even used Wireshark to watch the network traffic but couldn't find any big differences between PHP and SSMS versions. But I don't know too much about networking layers.
So the CPU load is low, there is no HDD use at all, the network transfer rate is extremely slow and the SQL server would be capable to deliver the results very much faster. And it actually is a lot faster with SSMS on the same PC and network connection.
Why is sqlsrv so very slow?
Any ideas what might be the issue or what I could try to speed up PHP/sqlsrv would be greatly appreciated.

Please tell us what are waits assigned to query, you can use below tsql code to get the information.
select session_id, t.text, start_time, status, command, db_name(database_id) As DBname, USER_NAME(user_id) As UserName, blocking_session_id, wait_type, wait_time, wait_resource, percent_complete from sys.dm_exec_requests
CROSS APPLY sys.dm_exec_sql_text(sql_handle) as t
This information can help us to understand the problem.
Thanks,
Shashikant
Sadly I don't have the rights on the SQL Server for this query. But from what I gathered from similar issues on the web, SQL Server is most likely waiting for the client.
I also tried the same testing query now with Power Query in Excel. It's as fast as with SSMS. Just with sqlsrv on PHP it's extremly slow.
Testing the query on a local SQL Server, it's pretty much instantaneous with SSMS, Excel and sqlsrv on PHP as well.

Software updates download is very slow

Today I downloaded 2 software updates; OSX 10.9.5 and Safari 7.1. The download speed was very slow and erratic. The activity monitor showed that the process "softwareipdated" was receiving data at anywhere from 1 to 25 kbs. My DSL connection is never very fast but typically receives 130 to 150 kbs. Other downloading such as streaming music or video has been normal. Any ideas why this happened and could this be a symptom of some more fundamental problem?

It may not be exclusive to Verizon but considering that Apple updates are severely affected on my system, yet my next door neighbor with Comcast has no problems whatsoever, I am 100% confident that Verizon is playing a role in my woes. In fact, I updated my wife's iPad to iOS 8 OTA on a relative's Xfinity wifi just to get it completed. Took me about an hour to complete. I came back home, less than a quarter mile away to my lovely FiOS and boom, 15-20 hour download estimate on my rMBP to update my iPad Mini (which I'm saving for last or at least until this issue is resolved). Changing my DNS seemed to work briefly on my rMBP but less than a day later my speeds were back to being slow as molasses. At least I had the opportunity to update both my rMBP and iPad Air before the speed took a nosedive again. Just wish I had updated the Mini too. I figured the problem was resolved and I'd get a chance to update it later.
Judging by several posts I found online (links to two examples posted below), I see I'm not alone in thinking something funny is going on between Apple and Verizon. I won't refute your claim that it is also affecting other providers, because your experience sounds pretty close to mine, but everyone I've encountered with problems in this area has FiOS. Folks around me who subscribe to other ISP's seem fine. The link below to the discussion on dslreports (2nd link) is particularly telling because I read it after trying various troubleshooting steps and was surprised by the number of people who posted in that thread that had identical issues and troubleshooting experiences as me. Several people also mentioned that the problem disappeared after they connected to Apple update through a VPN.
I assumed it was primarily on the East Coast because I have relatives in the West and Midwest with FiOS who have not had any issues.
I called Verizon but that was about as useful as your experience. They didn't even bother pointing fingers. They simply said "if everything else works then I'm getting what I pay for". I promptly replied that as an almost exclusively Apple household, I am most certainly not getting what I pay for if I can't upgrade my software, apply security patches or use my Apple streaming devices. Unfortunately, no one seems interested in fixing the issue, so we're left to find our own solutions.
And that's exactly what I did roughly an hour ago. Comcast will be out to swap my equipment and service in 14 days. Problem solved... At least I hope.
