Azure VM speed

i have hosted a web application in VM, but i am not getting enough speed when i access that website.
I must have missed something while configuring the server. But i am not getting what?

Hello parish mhatre,
I understand that you are not getting the required performance after hosting your application on the Virtual machine.
There are several factors that contribute to the performance(speed) of your applications hosted on the Virtual Machines.
Please answer these questions to help me understand the performance issue better.
1. What type of the application are you hosting?
2. Do you have any Database hosted for this application?
3. What is the size of the VM on which you have hosted your application?
I suggest that you start by looking at this application that talks about 'Best Practices for Performance in Azure Applications':
http://azure.microsoft.com/en-us/documentation/articles/best-practices-performance/
You can try to profile your application. I suggest that you follow the link below that will give you information on 'Testing the Performance of a Cloud Service':
https://msdn.microsoft.com/library/azure/hh369930.aspx?f=255&MSPPError=-2147217396
Also refer to this link. It gives you complete information testing performance of your application Using the Visual Studio Profiler:
http://azure.microsoft.com/en-us/documentation/articles/cloud-services-performance-testing-visual-studio-profiler/
If this does not fix your issue, help me with the answers to my questions so that we can look into this further.
Thanks,

How do I increase video streaming speed on mobile?

I have a new Azure acct where I have uploaded many videos/blobs into one container. So far my Azure Media service/storage has 10560 MB of video content. I'm working on a phone app so its not live yet, no one is watching/no traffic. But when I play to test
the video directly in the url generated by the "source video" (Mp4) my videos are stopping to buffer when I watch them on my phone using my data connection. It's not a problem with my mobile device or service provider because when I watch youtube
or facebook etc their videos work fine, they don't ever pause.
The Azure videos streams better only when I watch the videos with the phone's LTE feature on or perfectly when I'm connected directly to my office internet service/wifi. I don't want my future viewers to have any delays when watching my videos on the road
when they're using their cellular data connection. Therefore:
1) Where do I go in my Azure to fix this issue, what feature ?
2)And when I do get traffic what else do i need to increase if different? I read this under but I don't know if this applies to my case and what each unit will do because I increased the streaming units from 1 unit 200mbps to 3 units 600mbps but that made
no difference.

Hi Manu,
I saw your links thanks but you did not answer my questions.
We have no problems in streaming the videos blob type, storage type, storage version, cache etc and we're not looking to use smooth streaming or much less Silverlight etc.
I was talking about VIDEO SPEEDS in IN A MOBILE DATA CONNECTION. See Azure's "video test" page under and see how they also buffer/constantly stop in a mobile data connection. So it's not me it's AZURE!
The issue we're having I believe is between the video's speed play between "Azure servers" and an ISP company, example "Verizon Wireless". So being that a "mobile phone data" connections is slower than a "direct" (non-open
public) "wifi" connection, Azure should compensate their connection speeds for these connections. Some time ago it was known that ISP Verizon etc were slowing down video speeds from Netflix etc. mashable
article. I don't think we're at that level, but I think Azure speeds are not compatible to play on mobile "data" connections.
so question is ...What are the Azure delivered speeds ? and who can so something about it?
**Test these 2 links on your cell's "data connection" and then compare with your home/office connection and see the difference.
Also then just play a youtube or facebook, vimeo and see how they perform well on your data connection but Azure test page video does not.

SQL Azure - Intermittent The wait operation timed out

I have a website engine which runs a few hundred "white label" sites. It's hosted on Azure with a SQL Azure Business database. Generally everything is fine - it all works and runs at a good speed.
However, throughout the day I get maybe 40 or 50 of the error:
System.ComponentModel.Win32Exception: The wait operation timed out
Please don't refer me to the connectivity blog at http://blogs.msdn.com/b/sqlazure/archive/2010/03/22/9982979.aspx as this seems to refer to problems where you just can't connect. My problem is that it's fine most of the time, but I still get these
intermittently.
This is sometimes on the main database, but we're also using a database for sessions and this gets the errors too. Both databases are on the same server.
I also get errors like:
An existing connection was forcibly closed by the remote host
and:
System.Data.SqlClient.SqlException: The service has encountered an error processing your request. Please try again. Error code 40143. A severe error occurred on the current command. The results, if any, should be discarded.
and, when evil bots are hammering the site:
System.Data.SqlClient.SqlException: Resource ID : 1. The request limit for the database is 180 and has been reached. See 'http://go.microsoft.com/fwlink/?LinkId=267637' for assistance.
Each website can potentially have a Google footprint of around 10,000 pages. The result it that bots are hitting the sites regularly, indexing lots of pages for hundreds of sites. I also have some worker roles doing data work. The database is clearly busy!
I am hoping to add 2 or 3 times the number of sites that I currently have to the "engine".
I am looking at efficiency where possible, but the sites are clearly under a fair load from bots and visitors.
My question is, will one of the upgrades from Business to S2, P1, P2 or P3 resolve these problems? The financial cost of these database instances stagger greatly so I wouldn't want to update and find I'm left with the same problems but am paying many times
more each month.
Thank you in advance.

Hello,
For Web/Business edition database, the maximum limit of concurrent requests is 180. Beyond this limit, you will receive error.
The Max woker threads for Standard(S2) is 100, you should upgrade your database to Permium tier.
The concurrent requests limit of premium database varies depending on the reservation size of a premium database. For example, for P1, the max worker threads is 200.

How do I improve performance while doing pull, push and delete from Azure Storage Queue

Hi,
I am working on a distributed application with Azure Storage Queue for message queuing. queue will be used by multiple clients across the clock and thus it is expected that it would be heavily loaded most on the time in usage. business case is typical as in
it pulls message from queue, process the message then deletes the message from queue. this module also sends back a notification to user indicating process is complete. functions/modules work fine as in they meet the logical requirement. pretty typical queue
scenario.
Now, coming to the problem statement. since it is envisaged that the queue would be heavily loaded most of the time, I am pushing towards to speed up processing of the overall message lifetime. the faster I can clear messages, the better overall experience
it would be for everyone, system and users.
To improve on performance I did multiple cycles for performance profiling and then improving on the identified "HOT" path/function.
It all came down to a point where only the Azure Queue pull and delete are the only two most time consuming calls outside. I can further improve on pull, which i did by batch pulling 32 message at a time (which is the max message count i can pull from Azure
queue at once at the time of writing this question.), this returned me a favor as in by reducing processing time to a big margin. all good till this as well.
i am processing these messages in parallel so as to improve on overall performance.
pseudo code:
//AzureQueue Class is encapsulating calls to Azure Storage Queue.
//assume nothing fancy inside, vanila calls to queue for pull/push/delete
var batchMessages = AzureQueue.Pull(32); Parallel.ForEach(batchMessages, bMessage =>
//DoSomething does some background processing;
try{DoSomething(bMessage);}
catch()
//Log exception
AzureQueue.Delete(bMessage);
With this change now, profiling results show that up-to 90% of time is only taken by the Azure Message delete calls. As it is good to delete message as soon as processing is done, i remove it just after "DoSomething" is finished.
what i need now is suggestions on how to further improve performance of this function when 90% of the time is being eaten up by the Azure Queue Delete call itself? is there a better faster way to perform delete/bulk delete etc?
with the implementation mentioned here, i get speed of close to 25 messages/sec. Right now Azure queue delete calls are choking application performance. so is there any hope to push it further.
Does it also makes difference in performance which queue delete call am making? as of now queue has overloaded method for deleting message, one which except message object and another which accepts message identifier and pop receipt. i am using the later
one here with message identifier nad pop receipt to delete message from queue.
Let me know if you need any additional information or any clarification in question.
Inputs/suggestions are welcome.
Many thanks.

The first thing that came to mind was to use a parallel delete at the same time you run the work in DoSomething. If DoSomething fails, add the message back into the queue. This won't work for every application, and work that was in the queue
near the head could be pushed back to the tail, so you'd have to think about how that may effect your workload.
Or, make a threadpool queued delete after the work was successful. Fire and forget. However, if you're loading the processing at 25/sec, and 90% of time sits on the delete, you'd quickly accumulate delete calls for the threadpool until you'd
never catch up. At 70-80% duty cycle this may work, but the closer you get to always being busy could make this dangerous.
I wonder if calling the delete REST API yourself may offer any improvements. If you find the delete sets up a TCP connection each time, this may be all you need. Try to keep the connection open, or see if the REST API can delete more at a time
than the SDK API can.
Or, if you have the funds, just have more VM instances doing the work in parallel, so the first machine handles 25/sec, the second at 25/sec also - and you just live with the slow delete. If that's still not good enough, add more instances.

Azure Data Sync Log Take Too Much Time to Load

Hi,
I've found that the Azure Sync Log inside the Portal take too much time to load if my sync group was created long time ago. i.e. for those new sync group with only a few logs, it will take around 5 seconds for loading. However, I've many sync group created
more than 1 year, and it will take me up to 10 minutes for viewing the first page of the logs.
It seems the Portal will download ALL the logs to my browser even I just want to view the most recent logs (maybe I just want to view the last 10 records, but it will download the whole 5000 pages?)
It will be great if the Portal only fetch the data of the page I am currently viewing, instead of fetching all the logs.
Is there any ways to speed up the log loading time?

How to check upload progress when using Azure Node.js SDK createBlockBlobFromLocalFile

We are building our cloud application using node.js.
The "createBlockBlobFromLocalFile" API can be used to upload a local file to a container. However, is there any feedback event being fired so that I know how many bytes have been uploaded so far? (For example, if I am uploading a 4GB
file, I would need to know the upload speed and upload progress.)
Thanks.

Hi,
As of now, we do not have any API for Node.js to track the progress of Upload or download of block blob.
You may check the upload speed using different tool or through Azurespeed.com. Please refer below link:

Trouble with port forwarding, DHCP, VUZE, and downloading speed.

I am using Vuze to download things. I have a slow download speed and yellow smiley face, indicating a NAT problem. I think I need to implement a port forwarding, but that requires a static IP address. My router and security is set up such that I CANNOT connect to the internet using a manual configuration--DHCP only. However, I always have the same IP address. This is because the wireless router--a Motorola SB900--will only recognize approved computers designated by the IP address.
Can anyone advise on what to do next?

you are dealing with two networks. There is a network between your computer and your router. There is a second network between your router and your ISP.
Port-forwarding is from your router to your computer.

You need to set Port-forwarding between your computer and your router. You will need a fixed IP address on a your Computer. There is to ways of doing this. You can set up a static IP address on your computer. A hack would be to add 10 or 20 to your IP address that your router gives out. For example if your router gives out 192.168.1.10 you of would add 10 to the ten giving 192.168.1.20. you need to make the addition to the right most number of which in the example is ten.
The section way is . . . You can have your router a signed a fixed address based on your MAC address. ( Each Internet device has a fixed address that is called the MAC address. This is a different address than your IP address. the MAC address is assigned in the factory. )
Another hack would be to Port-forward to the number your router assigned at random. If your Computer is the only computer on the router, the number should always be the same. It is a hack because this is not guaranteed.

Creating an Azure VM from an existing snapshot, does not automalically create a certificate for remoting

Hi,
As the title says, I have problems with an Azure VM created from an image I captured of an Azure VM.
For easier deployment of my server I created one, running everything on localhost, such that I could take an image of it and re-deploy this image, by which I will speed up the process of creating a server substantially. However, this process requires me to
be able to remotely control the azure VM, such that I can reconfigure the server to use the new name.
My problem is that the certificate which is usually created automatically for me (under the cloud service on which the VM is created), is not created when I deploy a server on a new cloud service from this snapshot I have made.
Can anybody help me?
Thanks in advance!
Regards
Magnus

Hi Susie,
Sorry for the late answer, I've had a busy last week. Thank you for answering.
You're quite right. The scenario you describe is exactly what I've done. The reason for doing this is because I am creating a script for installing my company's product on an Azure VM. I am using powershel for this purpose and therefore I need to be able
to remote control it from powershell.
So far I manually transfered everything, but as it is ~70GB of files it takes alot of time. So I tried installing everything on localhost (which works perfect) and taking a snapshot of the machine, but when I spin a new Azure VM up from this image I need
to change a few database references and IIS settings in order to make it work. To do this I was hoping to be able to remotely control the machine with powershell, but since it does not create a certfificate I cannot do this.
Furthermore creating and uploading a certificate will, from my understanding, require me to install it on the server, which in turn will need me to manually do some work anyways, where as the whole idea of automating the process is lost.

RTL 8188CE poor speed with fluctuations on Wind box DC111

Hi everyone,
I have a problem with speed with my WIFI adapter ( RTL 8188CE in AzureWare AW-NE139H ). I think that the problems may be in the drivers.
The "Local Area Connection Status" report speed between 90 and 120 Mbps but when I start copy files from another pc connected to router via LAN the transfer speed is less than 300Kb. When I place the router to 1 meter from my Wind Box the transfer speed is less than 4Mbps and have a lot of fluctuations. My router is TP-Link WR843ND and I haven't any problems with it when I use my laptop or mobile devices. I try the drivers from MSi site, from Realtek's site and from azure ware. I use Windows 7 64bit. When I test it on Windows 8.1 64bit the problem was worst - the speed was less than 100Kb.
Does someone have any idea how to solve the problem. I Googled a lot but without luck.
My system is: Wind Box DC111( RTL 8188CE in AzureWare AW-NE139H ), Windows 7 64 bit, router TP-Link WR843ND

You can try the Realtek driver if you think it's driver related: http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true

How to improve performance for Azure Table Storage bulk loads

Hello all,
Would appreciate your help as we are facing a challenge.
We are tried to bulk load Azure table storage. We have a file that contains nearly 2 million rows.
We would need to reach a point where we could bulk load 100000-150000 entries per minute. Currently, it takes more than 10 hours to process the file..
We have tried Parallel.Foreach but it doesn't help. Today I discovered Partitioning in PLINQ. Would that be the way to go??
Any ideas? I have spent nearly two days in trying to optimize it using PLINQ, but still I am not sure what is the best thing to do.
Kindly, note that we shouldn't be using SQL/Azure SQL for this.
I would really appreciate your help.
Thanks

I'd think you're just pooling the parallel connections to Azure, if you do it on one system. You'd also have a bottleneck of round trip time from you, through the internet to Azure and back again.
You could speed it up by moving the data file to the cloud and process it with a Cloud worker role. That way you'd be in the datacenter (which is a much faster, more optimized network.)
Or, if that's not fast enough - if you can split the data so multiple WorkerRoles could each process part of the file, you can use the VM's scale to put enough machines to it that it gets done quickly.

Use SQL Azure with local web app?

Hello all-
I have a web app running on a local-ish (our Data Center) server which runs ColdFusion and SQL Server on the same physical hardware. The load for the app is not too great, so running both services on the same box is not problem.
I need to upgrade SQL Server, and I would prefer not to put more resources onto our local servers if possible. Essentially, I would like to move to the cloud. BUT at this point I don't want to move my code to the cloud due to file storage and
a few other issues.
Is it feasible to use SQL Azure as my datasource for my local web app? I am at a top-tier University on the west coast, and our connection speeds are about as good as you can possibly get.
I don't mind a minor slowdown. For instance, if the round-trip takes 30 milliseconds, I won't be sweating that. But I'd rather not have a relatively snappy app turn into something agonizing for users.
Also, we have a perimeter firewall on campus which normally blocks all SQL Server traffic. Is it possible to change the port that SQL Azure uses?
Any guidance would be appreciated.
Thanks-
Karl

Exceptional slow batch operation for Azure Table

I have a VM Medium with an Azure Storage.
West Europe
Same Affinity Group
Different storage account for VM and for my application
I noted that today, during the afternoon, my storage became very very slow all of a sudden.
I was happily uploading my batches with the rate of 2 MB/S, and now, suddenly this afternoon, I started to get better than 300KB/S.
I noticed that my network and CPU activity were very low.
I started Fiddler, and seen that my batches of 100 KB approximately took 14 second to upload !
I tested the same program on a VM in a different subscription with different affinity group, the same exact same batch took 200ms approximately.
What can do enjoy my full speed again ? Seems like a mouse is eating the cable of my rack.

Update :
I eventually it the threshold with a new table, my insert on the other table are starting to take more than 2 seconds to process, and it goes up with time.
So, insert is not constant, but depend on partition's size. Is it normal ?
Niranjan Nilakantan of Microsoft said
If the key for your logical data model has more than 1 property, you should default to (multiple partitions, multiple rows for each partition).
If the key for your logical data model has only one property, you would default to (multiple partitions, one row per partition).
We have two columns in the key to separate what defines uniqueness(PartitionKey and RowKey) from what defines scalability(just PartitionKey).
In general, write and query times are less affected by how the table is partitioned. It is affected more by whether you specify the PartitionKey and/or RowKey in the query.
If this is true, there is a real problem with my storage node.

Can I use Azure Backup and Windows Server Backup in a Windows Server ?

Can I use Azure Backup and Windows Server Backup in a Windows Server ?
I want to use both Azure Backup and Windows Server Backup for two senarios.
For Disaster Recovery = Azure Backup to Azure Storage.
For non-Disacter Recovery = Windows Server Backup to a on-premises disk.
The non-Disaster Recovery mean a file or folder recovery, disk crash recovery, migrate to another servers.
The non-Disaster Recovery need the speed of recovery just like 10 TB recovery as soon as possible.
If I can use both Azure Backup and Windows Server Backup in a Windows Server,
Are there any notes for using both ?

Hi Yoshihiro Kawabata,
Thanks for posting here!
Azure Backup to Azure Storage and Windows Server Backup to a on-premises disk. These are two different question and can be answered individually.
Azure Backup to Azure Storage - Possible.
Windows Server Backup to a on-premises disk - Possible.
Can I use Azure Backup and Windows Server Backup in a Windows Server? Is a question.
I will check on this and get back to you at the earliest.

Slow Networking Speed

Hey,
I am getting some problem with the Internet on my virtual machine. I tested the speed with speedtest-cli tool, its showing me
Download: 26.03 Mbit/s
Upload: 13.28 Mbit/s
but the actual speed i am getting is :
100 - 200 kbps as downloading
and upload speed is also very slow.
how can i get the fast internet speed???
kindly resolve this issue.
Thanks in advance.

Hello Hemant Thakur,
1. What is the size of the Virtual machine that you have deployed on Azure?
There could be several reasons that the VM has a network performance issues. To check if there are any issues on the platform end, I suggest that you try the steps below:
I suggest that you restart your Virtual Machine to see if it makes the difference. You can do this by logging into your Virtual Machine or from the Azure Management portal.
If this does not work, I suggest that you resize your Virtual Machine. You can refer to the link below that will give you information on how to accomplish this:
https://msdn.microsoft.com/en-us/library/dn168976(v=nav.70).aspx
If these steps do not work, we might have to further invertigate this issue. I suggest that you create a Support ticket with us. You can follow the link below to create a Support ticket:

Bandwith issue in azure virtual machine

Hi,
Suddenly from last two three days we are not getting proper bandwith on one of our azure virtual machine ,uplaoding and dowloading speed which we are getting is below 30mpbs ,so please look in to this issue.

Hello siddheshr,
1. What is the size of the Virtual Machine that you have deployed?
2. When you say that there is a latency, are you referring to Azure VM to VM latency or from external traffic?
If you have a latency in your bandwidth, as a first step, I suggest that you restart your Virtual Machine and check if it makes a difference.
If restarting the Virtual Machine does not fix the issue, I suggest that you resize the Virtual Machine.
Also, please let me know how exactly are you determining that the bandwidth is low.
Thanks,
