Files upload speed in sharepoint2013

What should be the optimum speed while uploading files from file system to sharepoint, we are getting aroung 600KB/sec
But users want it more they compare it with normal trasfer speed rate which is around 50MB/sec.

It depends.
You have various 'bottlenecks' in file transfers, the main three are below:
Source disk speed
Intermediate network connection
Destination speed
Assuming that you're doing a like for like comparison (ie. all variables are the same except the user is accecssing a FileShare instead of a SharePoint server) then the most likely bottleneck is SharePoint and SQL, which will combine to limit your performance.
Out of those two the most likely and most adjustable is SQL so i'd cast your eyes there.
With the exception of the performance improvements possible with Shredded storage/cobalt SharePoint will always be slower than a File Share. It has far more to do than a FileShare does.

Ichat file upload speeds really slow

i am having issues with ichat file upload speeds.
I'm sending a 1.5MB file and it's took 6+ minutes - one time it took 12 minutes!
The same file sent back to me only took 40 seconds.
The strange thing is it took 15 seconds to email the file, and 7 seconds to send the same file through Skype.
There seems to be some issue with ichat. I've cost moved offices and when I was working from home it was not an issue.
Any ideas?
Thanks.

Hi,
Welcome to the  Discussions
Are you dropping the file on the Buddy in the Buddy List ? (Peer-to-Peer)
If you are sending in a Text Chat the Chat has to Change to a Direct IM first which is Peer-to-Peer.
If you don't have the port open for the Direct IM iChat may try to route it through the AIM servers which will be longer. (normally it fails)

Possible to show file upload progress for web form submission?

I just made a simple form as a test. There are 3 files being submitted here via a "web form".
Files being uploaded in this case are of these sizes:
110MB
9MB
24MB
I'm testing functionality that will let a print shop's clients upload their files. For larger files they'll use FTP but this "order form" does a lot of business for them so we're trying to replicate in BC.
My problem is that I am wondering if there is a way to show the "upload progress" as a total %. Such as a visual status bar, etc.
As of now the only way it's showing is in the default browser status bar (chrome in this case):
http://cl.ly/image/1d3U0S1h2521
I read somewhere that the limit is 150MB for an upload. Wondering if that means 150MB TOTAL as in 3 files combined in my case. Or If I chose to allow 3 files to be attached would it allow for 450MB?
Also, if you do a user submitted web app instead and allow people to attach files that way, does the same file limit apply?
My second issue is that the upload speed seems to be SLOW. I know it's not my connection because on my non BC site as well as another with the same form, the files upload fairly fast. But on BC it just crawls and on a few tests I get this:
http://cl.ly/image/2T2q160M1R1n
Any help or suggestions with the file upload progress as well as file upload speed would be appreciated.
Thanks!

So if i have 3 files to be uploaded, the max allowed is 750MB correct? (just wondering if when uploading its 250mb total or per file).
Guess i'll do something fake to make it appear its working with a loading graphic or something.
My web browser (chrome in this case) shows the % uploaded. I wonder if all web browsers do the same. I havent tested yet.
If only there were a way to have javascript or something grab that same #% from the web browser itself and just format it to appear where I want on the form along with the % uploading.
Anyone know if that's possible?
Here's where Chrome for mac shows it:
http://cl.ly/image/1c3i3x25262j
If I could grab that (uploading 19%) from the browser and format it into css/html i'd be gold.
Then find if similar browsers do the same and write some js for each browser specifically to grab it.
In a perfect world at least....

How to speed up ProgressEvent.PROGRESS to catch small file uploads?

Hi there,
I'm uploading some files to a server. On Mac OSX the Event.COMPLETE listener does not work. It works fine on Windows, but not on OSX.
So, to test if a file is complete I'm monitoring the ProgressEvent.PROGRESS listener. This works pretty well most of the time on OSX and 100% of the time on Windows.
My problem is that when I try to upload files that are about 100kb or smaller on OSX, the file apparently uploads so fast that a ProgressEvent is never fired or it's missed and so my script doesn't know the file is complete. I'm testing if bytesUploaded == bytesTotal and small files never seem to register anything in the ProgressEvent. However, files larger than 100kb and up seem to work file and the progress bar moves and I can register when the file is done. This is only OSX.
Is there way that I can somehow speed up how fast the ProgressEvent is called to listen so it can catch small files' progress?
Any ideas on how to overcome this? I wish Event.COMPLETE would work on OSX with my host but it simply won't after weeks of testing we can't get it to work so monitoring the ProgressEvent is the only other alternative method of trying to tell whether a file is complete or not. If anyone has any "Plan C" ideas I'm open to that too.
Thanks!

Hi there,
If my memory is not cheating on me then this is a Mac issue. The solution would be to send some additional data, like an empty echo that would force the COMPLETE event to trigger. Try googling for this issue because I'm sure that you'll run over a few articles that can help you out if you insist a bit.
With best regards

Upload Speed with file hosting sites

My upload speeds have gone down from ~1mb/s to 1-30kb/s. It has been consistent like this for a couple weeks now. I've tried mediafire, megaupload, uploaded.to, and zshare and they all upload this slow. Torrents still upload fine,
I've tried figuring out what port they use for uploading so I could see if it needed to be open, but no luck.
I'm running ubuntu 9.1. My router is Westell A90 9100EM15.

Have you tried resetting the router?

Rename file extension during a file upload ??

I need to rename the extension of a file at some point during the file upload. I am not sure where to do this at.
The file needs to be renamed before it is written to the directory.
Basically, the file will come in with a .txt or .doc type. Based on a users profile, I will change the type to a non-relavent number such as 1111.
Here is my upload servlet. Can you tell me where to change the type so it will write the file with the new extension?
Thanks.

Excel file upload in background

Hi
any one inform me how to Excel file will be Executed as a background job.
The Excel file will be executed as a background job.
This will eliminate issues related to network speed,
time-outs,user logging off,ect;
and the need for the user to remain logged in to the transaction till it finishes
execution. After the background job completes the output report will be sent to the
user via email as an attachment.
Regards
Gopal
Duplicate thread.

hi,
function module for email attachment -
function module SO_DOCUMENT_SEND_API1
function module for background schedule - u2018ALSM_EXCEL_TO_INTERNAL_TABLEu2019
When scheduling a job in the background the appropriate statement to read in your file is OPEN DATASET, and the file must be on the file system that the SAP server can see.
At anytime, a user can switch of the Personal Computers even though the job is still running in the background. Therefore GUI_* and WS_* function modules are not designed to work in that way, as they need to access your personal computer file.
To choose the correct download method to used, you can check the value of SY-BATCH in your code,
if it is 'X' use OPEN DATASET and if it is ' ' use WS_UPLOAD.

Why is the upload speed for "downloadable product" so slow?

Upload speeds are normal with other adobe services, but when it comes to uploading my product, the speed continually decreases to a crawl, making it impossible to get my product online. It starts slow: at about 20kB/s and then drops to 3kB/s!
Any suggestions?
Thanks.

hi Sanjit,
Using safari, only one one file was being uploaded, no other browsers or windows open. On a whim, decided to add " https:// " before the address after logging into BC... it made an improvement in the upload speed. Am now getting about 50-54kB/s. It's useable, but still slower than it should be.

IPad (and iPhone 4) upload speed on wi-fi very slow - any thoughts?

Both my "i devices" - an iPad and iPhone 4 are very slow for upload speeds on wi-fi. For example, here are the results of using speedtest.net on my iMac 21.5", iPhone 4 and iPad just now:
iMac: download 38.39 Mbps, upload 19.22 Mbps (so the wi-fi network itself has good upload speeds)
iPhone 4: download 21.17 Mbps, upload 0.39 Mbps (why so slow?!)
iPad: download 23.66 Mbps, upload 0.71 Mbps (why so slow?!)
The wireless router is an Airport Extreme updated to the latest firmware.
I've seen screenshots of other people's iPad and iPhone speedtest.net tests where the upload speed over wi-fi doesn't suffer compare to download like mine does, by a factor of 54!
I've seen postings here and there by people with similar problems. Are there any solutions? Are my iPad and iPhone 4 bad? Are they incompatible with my Airport Extreme? Are there "settings" somewhere that can help with the problem?
Any advice would be appreciated.
Thanks.

Hi, Carolyn.
Perhaps so. Maybe there are certain kinds of connections which are better suited for iPads and iPhones than others. But the download speed on neither device seem to have problems. It's just the upload speed.
I did try several channels yesterday - 6 through 13 - but it didn't seem to make a difference.
Why would trashing my Mac preference files and restarting my Mac help anything? My Mac isn't having any problems.
Oh, by the by, on my iPhone at least I already tried resetting Network preferences. I even did a Reset > Erase All Content and Settings and re-installed my iPhone 4 from scratch. While still in a "vanilla state" before restoring from my backup, I tried testmyiphone.com via Safari and got similar results - very poor upload.
The 3G connection also fluctuates between "so so" (1-2 Mbps down, 0.8 Mbps up) and really horrible (0.2 Mbps down and 0.05 Mbps up).
I did just try your suggested "reset networks" on my iPad. This time I got a download of 13.26 Mbps and upload of 2.2 Mbps on the first test. On the 2nd test I got about the same download, but an upload speed of just 0.63 Mbps.
So something's still wrong.

Silly Questions - Upload Speed & Hardware

Hi tere network people,
Networking ignorant here in need of your help.
I'm using a PowerMac G4 as a server and I have a PHP website going to share some pics with friends.
Some lamented it can be slow to download the pictures on their side (Most, if not all, have Broadband). The picture files are not huge, but my connection is only a residential Broadband one.
The ISP states that: "The upload speed is 256 Kilobits/Sec. Average upload rates are circa 20 Kilobytes/Sec."
Coming to my silly questions:
1) How much my Upload speed should be to confortably support 5-10 users at a time?
2) Since I got a new PM G4 with a 7200 rpm HD and a Gigabit Ethernet port and a slightly faster processor, should I look at the modem/router specs? Can they affect/limit upload speed?
If anyone can give me some basic tips, I'd be grateful.
Cheers!
PM G4 (PCI Graphics) - 350Mhz, 128-bit, 100 MHz, L1 Cache: 64K, L2 Cache: 512/1M, CD-Rom, 10GB Mac OS X (10.3.5)
PM G4 (PCI Graphics) - 350Mhz, 128-bit, 100 MHz, L1 Cache: 64K, L2 Cache: 512/1M, CD-Rom, 10GB Mac OS X (10.3.5)

1) How much my Upload speed should be to confortably support 5-10 users at a time?
That's easy to calculate.
Assume that your 10 users are on broadband connections with a 1mbps download speed. In order to fulfill everyone's demands at top speed you need a 1mpbs x 10, or 10mpbs upload speed.
Of course, it's unlikely that everyone will download files at the same time, and it's also unlikely that they'll sustain 100% of their rated download speed, so you can probably halve that figure without any noticeable degradation, but even 5mpbs is way higher than your current 256kbps upload link.
It's also clear that your internet connection is your bottleneck. Upgrading the server isn't going to make any difference.

Macbook upload speed suddenly slow see history

Hey there,
So my wife has the white Macbook from september 2008 and I have the Macbook Pro 15in from March 2009. We both share the same internet connection but after the upgrade to SL her upload speed has become painfully slow (see history) while mine is still the same speed.
Date Download Speed Upload Speed
Tuesday 00:55 984 kbps (123kB/s) 27 kbps (3.38kB/s) Share
Tuesday 00:06 989 kbps (124kB/s) 19 kbps (2.38kB/s) Share
Sep 4, 22:01 1059 kbps (132kB/s) 120 kbps (15kB/s) Share
The september 4th speedtest was BEFORE the SL upgrade and the tuesday is AFTER the SL upgrade, but then again I upgraded my Macbook Pro to SL and there has been no drop in my upload speed.
What to do? My wife is now using my Mac which is no good for any of us.
Thanks
Thomas

Select each of the items shown in RED in Activity Monitor. Click on the Quit icon in AM's toolbar then click on the Force Quit button. You only need to do this if you are unable to quit the programs in the normal way - Make the program the frontmost application, then press COMMAND-Q.
You also have two items in the /Library/StartupItems/ folder. They should not be there. You can remove them. HP should have updated software that replaces the older driver. I'm not sure about the TiVo item, but it should not be installed in that location.
You should check the Classroom Enrichment application for compatibility with Yosemite: See App Compatibility Table - RoaringApps.
As for your backup needs I would suggest this:
Repartition the Seagate backup drive. This removes all the Seagate software. If you want more control over your backups than provided by Time Machine see the following options:
Suggested Backup Software
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Others may be found at MacUpdate.
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. You can download free trial versions of all six so you can try them out and decide on the one you prefer before paying for it. I am a big fan of Carbon Copy Cloner, but that does not mean it's your best choice.
Now given all the above consider that you can always use Time Machine. But until you get your computer straightened out I would refrain from making a backup. There's no point in restoring a malfunctioning backup made of a malfunctioning computer.

How do I increase the file download speed?

When downloading outside of firefox, I manage anywhere from 5mb/s to 16mb/s, depending what I am downloading and where from. Yet, when a file has to download from within the browser, it downloads at 1/30th to 1/10th of that if I am lucky. Is there some kind of restriction built in to firefox that I might be able to change or am I just S.O.L?

Download / upload speeds depend on 3 things.
* The speed of the ISP
* The speed of the sender
* The speed of the receiver
Since you seem to have decided Firefox is the issue, lets work on that.
Go to the '''[https://addons.mozilla.org/en-US/firefox/ Mozilla Add-ons Web Page]''' {web link}
(There’s a lot of good stuff here) and search for a download manager.
There are also external programs that can be used.

File Transfer speed...Huge Topic

Hi guys,
I've read lots of stu regarding file upload/download speed, but none of the tips I've read has fixed my problem.
I have 2 LANs, interconnected with 52Mbps line, no router between , only switches /___sbsstatic___/migration-images/migration-img-not-avail.png
On each sites, I have Windows servers.
With a windows client on site A, I can upload a 500 MB file to site B in 2 minutes.
My macbook (and in fact ALL Mac os X clients) needs 10 minutes /___sbsstatic___/migration-images/migration-img-not-avail.png
Downloading the same file from the windows Server takes only 2 min for both clients.
IF I start the upload from the windows server (I start a copy from win to Mac), then it takes only 2 min
So the same transfert, initiated from windows goes 5 times faster /___sbsstatic___/migration-images/migration-img-not-avail.png
More crazy, no problem with another windows server. If I go on site B, same issue with all servers located on site A. BUT again no problem with a windows client.
It doesn't have anything to do with the line.
I tried everything with nscmb.conf, tcpack, ... Nothing has changed...
Does anybody knows what's going on ?
I'm open to any tips
Thanks in advance

I wonder if the problem is that the disks are formatted NTFS which is native to Windows but not to the Mac. Hence there needs to be a conversion for the Mac. Could that conversion be taking the additional time?

File transfer speed when on battery power

Hey there - I've noticed that my file transfer speed is ridiculously slow when i'm not plugged in to a power source. Even when my battery is fully charged it's super slow. This happens not only when I'm uploading files from a memory card to my computer but when I'm attaching files to an email, or even sending an email. I've asked other mac users and they say this is not the norm for their machines....any ideas?
thanks!
Sunny

additionally, you can disable power menagement for your wireless card completely through iwconfig's power option. I suggest you read the manpage for iwconfig, I have quotes the 2 related options for you.
txpower
For cards supporting multiple transmit powers, sets the transmit power in dBm. If W is the power in Watt, the power in dBm is P = 30 + 10.log(W). If the value is postfixed by mW, it will be automatically converted to dBm.
In addition, on and off enable and disable the radio, and auto and fixed enable and disable power control (if those features are available).
Examples :
iwconfig eth0 txpower 15
iwconfig eth0 txpower 30mW
iwconfig eth0 txpower auto
iwconfig eth0 txpower off
power
Used to manipulate power management scheme parameters and mode.
To set the period between wake ups, enter period 'value'. To set the timeout before going back to sleep, enter timeout 'value'. You can also add the min and max modifiers. By default, those values are in seconds, append the suffix m or u to specify values in milliseconds or microseconds. Sometimes, those values are without units (number of beacon periods, dwell or similar).
off and on disable and reenable power management. Finally, you may set the power management mode to all (receive all packets), unicast (receive unicast packets only, discard multicast and broadcast) and multicast (receive multicast and broadcast only, discard unicast packets).
Examples :
iwconfig eth0 power period 2
iwconfig eth0 power 500m unicast
iwconfig eth0 power timeout 300u all
iwconfig eth0 power off
iwconfig eth0 power min period 2 power max period 4
website with the current manpage:
http://linux.die.net/man/8/iwconfig
or simply:
$ man iwconfig

Extreme slow upload speed in Dallas area

Hello
Something happened to my upload speed last Thursday, it has dropped considerably connecting to most servers making many sites very sluggish. I have the hardest time just attaching a file in Gmail and the gmail chat keeps saying 'unable to connect'. Using FTP for my work is almost impossible. It's takes me 5-10 tries to upload a file that's not even 50KB.
I've called Verizon tech support and went through different diagnostics and then they sent a new router, which still didn't help. Here's what I concluded so far:
It's not the router
It's not the computer since it happens on every machine
It's not the wiring since I can get good speed test connecting to some servers.
It's not the servers that i'm connecting to; everything works when i'm at work or on the phone.
I have 15/5, I've attached some speed test results.
Verizon's own speed test page even timed our during upload, which was stuck under 0.5 when it was about to finish.
Anyone else experiencing this? Verizon say my issue is currently with the engineers, but I have no idea how long that wait to be.
Thank you

Is there any Verizon representative that can escalate my issue?
Basically a tech came last Saturday and wasn't able to figure out what was wrong and left and closed my ticket. Whenever I call back now they're just telling me it's my computer, which is completely FALSE. All my 5-6 computer just doesn't happen to have slow upload speed of the sudden and require modification to RWin buffer as the suggested by the on-site tech. Verizon phone support bluntly told me they can't do anything further and would charge me for coming out again to replicate my issue.
Things the tech have already tried:
-Run Fios Optimizer multiple times on multiple computers.
-Replaced router
-Replaced ONT
-Rebooted PON card
Upload speed still sporadic, works perfect on some speedtests, but it's less than 0.5MB on many servers including Verizon's very own local speedtest. Gmail and any google site request is constantly slow. This site is slow and often times out. FTP to my own site is almost impossible if I want to upload a file that's bigger than 100kb.
I'm extremely frustrated.... There are reports of same exact issues in other thread, one seems to be fixed. Is there any way Verizon can look at that and apply it here?

Is it because I'm using a community account on this forum so I'm being ignored?
I've tried to sign up using my residential account, but got this yellow error page.
