Increase stream buffer size

Hello everyone,
my internet radio streams often stop or have to buffer although I have a bandwidth > 14.000 kBit/s. I read on forums that I should increase the stream buffer through the iTunes preferences. But I learned that the newer versions of iTunes don't have these preferences. Is there an alternative way? Maybe via terminal?
Thank you in advance for your help!
Greetings

Hi all, iTunes streaming victims.
I struggled long with the streaming buffer problem of iTunes and indeed could solve it with increasing the buffer size, which features has been removed in iTunes 10. And this without updating the instructions by Apple!
Here is my solutions:

perfect for all wireless audio streaming not only for itunes, but any source on the Mac.
solved the problem completely for my 3 MacBooks, 2 airports, iphones etc.
it is not for free but a very good value for money.

How do you increase the Streaming buffer size in iTunes 10

When I try to listen to the radio in ITunes it plays for 30 seconds then says rebuffering stream.
I just upgraded to an iMac and my old dinasaur G4 does not have this problem.
I've read things saying to increase the Streaming buffer size but I don't see how to do this anywhere.

I don't think that is possible with newer iTunes versions.

"Streaming Buffer Size" pop-up menu does not exist under Advanced when I use iTunes - Preferences - Advanced. How can I increase buffer size?

Will increasing the buffer size make flash streaming video stop stalling?

I have surmised all this on my own so it could be just a fantasy, but:
I am often the victim of slow internet connections. This means that when I try and watch streaming video it constantly pauses. It's my understanding that increasing the buffer size of flash would help prevent this but I can't figure out how to do that.
Thanks

You can pause the video just long enough for the player to load enough content. Most Flash player show a loading bar if you hover the player. For short pieces you can load the entire content before starting the play.

Indeed, we are using Bex Web 7.0
The query uses a big structure and when I execute it on the web, it takes a long time (> 5 min) and I receive folowing message on top of the result page : " could not buffer query structures. Buffer too small "
When I execute the query in Bex analyzer, it takes a long time too but we dont get the message

How to increase the buffer size for Oracle?

After I installed the patch 9.2.0.4, I kept getting 'ORA-03113: end-of-file on communication channel' error. According to the metalink, increasing the buffer size may solve this problem. I found when I set the trace on, this problem was gone, and after I set the trace off, it came back again. I am not sure if setting the trace on increases buffer size automatically or not, but I want to start from here.
No matter how easy it is, I really didn't change buffer size before, can anyone show me how to do that?
Thanks a lot.

Hi,
I think they asked to increase the db buffer cache size. You may try this
alter system set db_cache_size=<new size in bytes> scope=both;

Effect of Changing Stream Buffer Size

What is the downside (if any) of changing the Stream Buffer Size from Medium to Large when playing music files?

Streaming Buffer Size
Change how much audio or video is downloaded before it starts to play. Choosing a larger buffer can help video play more smoothly. If you have a fast Internet connection, a smaller buffer can help the movie start playing more quickly.

Increasing usb buffer size on HP Pavilion g6 / Windows 8

I have recently loaded Traktor Audio 2 DJ software and have run diagnostics on the system because of sound drag and distortion. The error message suggested increasing the USB buffer size to solve the problem. How do I do that - and do any forum members who use Traktor reckon that will solve the problem?

Best buffer size for BufferedInput/Output Streams?

I'm developing a client-server application where one server serves an undetermined number of clients. The server spins off threads to service each client individually. The clients send data (serialized objects) to each other via BufferedInput/OutputStreams wrapped in ObjectInput/OutputStreams. The streams are created like this:
toServer = new ObjectOutputStream(new BufferedOutputStream(theSocket.getOutputStream()));
fromServer = new ObjectInputStream(new BufferedInputStream(theSocket.getInputStream()));I've never had more than a handful (5-6) users on the system at one time, and it works fine. However, I haven't the resources to test the system with a large number of clients, and I'm wondering if the default buffer size is enough to handle a potentially large amount of traffic to a client. Should I increase the buffer size just in case, or should I not worry? Does the buffer size even matter when using an ObjectInput/OutputStream?
I'd appreciate any good advice.

There is an underlying buffer size of 1024 in ObjectIn/OutputStream anyway so the buffer should be at least this large. Generally 4k is adequate unless you are doing very high data volumes in which case 16k, 32k, 63k may help. If you are on Windows you should also up the socket send/receive buffers which by default are 8k: change this to at least 28k. The precise value depends on the network link & in theory should be >= the bandwidth-delay product.

I need to increase my FMS buffer size for display video smoothly

I need to increase my buffer size in FMS.
Please let me know form where i would be increase my FMS buffer size.
My video is running from RTMP and i faces the problem to load. video stalled between the running. so i need to increase buffer size for running video smoothly.
Please reply me as soon as possible so i can resoled my problem.
Thanks in advance.....

Hi,
You can increase the buffer size by using the property bufferTime of NetStream Object you are using. For eg: if ns is your NetStream Object then it can be done by ns.bufferTime=<desired value>.
Also you can go through this

Regd: Screen Buffer size increase

Dear Sir/madam,
We check in ST02. the screen Buffer -   SWAPS are More.
we want to increase the "SCREEN" Buffer size so the Screen Swaps comes down.
Screen buffer
zcsa/presentation_buffer_area    4400000          Byte   Size of screen buffer
sap/bufdir_entries               2000                    Max. number of buffered screens
Which parameter size i have to Increase here 2 Parameters are available. How much we can increase it.
here RAM size is 4GB. Any Formula is available to Increase the Buffer size of the Screen. or other like Program Buffer etc.
Regards
SNB.

Thanks for your Reply.
   Buffer            Hitratio   Allocated         Free space        Dir. size      Free directory         Swaps       Database
                        [%]       [kB]               [kB]         [%]      Entries         Entries       [%]                      accesses

if we want to increase we have to increase for both the parameters.
zcsa/presentation_buffer_area       4400000 + 440000 =          4840000 (10%)
sap/bufdir_entries                          2000 + 200 =                   2200   (10%)
What is the difference between thest 2 parameters.
1)                   zcsa/presentation_buffer_area
2)                   sap/bufdir_entries
Do you have any Formula to Handle ST02 Buffer Size Parameter Maintanence.

Why no "Streaming Buffer" option??

I am using iTunes 10.4 (80) on a MacBook Pro 2.16 GHz Intel Core 2 Duo running Mac OS 10.6.8.
iTunes help tells me that I can do the following: "You can also choose iTunes > Preferences, click Advanced, and choose Large from the Streaming Buffer Size pop-up menu."
However, in my iTunes, no such option exists at all. There is nothing anywhere in the Preferences relating to "Streaming Buffer Size."
The issue is iTunes radio, and very frequent drop-outs due to, I imagine, rebuffering.
Any tips??
Thanks!

Apple may remove the option from the iTunes but we still have the mighty terminal
To increase the buffer for stream type:
defaults write com.apple.iTunes stream-buffer-size xxxxxx
and for the file
defaults write com.apple.iTunes file-buffer-size xxxxxx
REPLACE XXXX with the number.
1024 = one kb
I use this:
defaults write com.apple.iTunes stream-buffer-size 128000
You can adjust how much buffer you want. But if you put too much it will buffer for ever so do not do 512000, it is too much.
I hope this helps someone.
Cheers

DBMS_LOB.WRITEAPPEND Max buffer size exceeded

Hello,
I'm following this guide to create an index using Oracle Text:
http://download.oracle.com/docs/cd/B19306_01/text.102/b14218/cdatadic.htm#i1006810
So I wrote something like this:
CREATE OR REPLACE PROCEDURE CREATE_INDEX(rid IN ROWID, tlob IN OUT NOCOPY CLOB)
IS
BEGIN
     DBMS_LOB.CREATETEMPORARY(tlob, TRUE);
     FOR c1 IN (SELECT ID_DOCUMENT FROM DOCUMENT WHERE rowid = rid)
     LOOP
          DBMS_LOB.WRITEAPPEND(tlob, LENGTH('<DOCUMENT>'), '<DOCUMENT>');
          DBMS_LOB.WRITEAPPEND(tlob, LENGTH('<DOCUMENT_TITLE>'), '<DOCUMENT_TITLE>');
          DBMS_LOB.WRITEAPPEND(tlob, LENGTH(NVL(c1.TITLE, ' ')), NVL(c1.TITLE, ' '));
          DBMS_LOB.WRITEAPPEND(tlob, LENGTH('</DOCUMENT_TITLE>'), '</DOCUMENT_TITLE>');
          DBMS_LOB.WRITEAPPEND(tlob, LENGTH('</DOCUMENT>'), '</DOCUMENT>');
          FOR c2 IN (SELECT TITRE,TEXTE FROM PAGE WHERE ID_DOCUMENT = c1.ID_DOCUMENT)
          LOOP
               DBMS_LOB.WRITEAPPEND(tlob, LENGTH('<PAGE>'), '<PAGE>');
               DBMS_LOB.WRITEAPPEND(tlob, LENGTH('<PAGE_TEXT>'), '<PAGE_TEXT>');
               DBMS_LOB.WRITEAPPEND(tlob, LENGTH(NVL(c2.TEXTE, ' ')), NVL(c2.TEXTE, ' '));
               DBMS_LOB.WRITEAPPEND(tlob, LENGTH('</PAGE_TEXT>'), '</PAGE_TEXT>');
               DBMS_LOB.WRITEAPPEND(tlob, LENGTH('</PAGE>'), '</PAGE>');
          END LOOP;
     END LOOP;
END;
Issue is that some page text are bigger than 32767 bytes ! So I've got an INVALID_ARGVAL...
I can't figure out how can I increase this buffer size and how to manage this issue ??
Can you please help me :)
Thank you,
Ben

Hi ben,
I'm afraid, that doesn't help much, since you have obviously rewritten your procedure based on the advise given here.
Coluld you please post your new procedure, as formatted SQL*Plus, embedded in {noformat}{noformat} tags, like this:SQL> CREATE OR REPLACE PROCEDURE create_index(rid IN ROWID,

10 dbms_lob.writeappend(tlob, LENGTH('<DOCUMENT>'), '<DOCUMENT>');
11 dbms_lob.writeappend(tlob, LENGTH('<DOCUMENT_TITLE>')
12 ,'<DOCUMENT_TITLE>');
13 dbms_lob.writeappend(tlob, LENGTH(nvl(c1.title, ' '))
14 ,nvl(c1.title, ' '));
15 dbms_lob.writeappend(tlob
16 ,LENGTH('</DOCUMENT_TITLE>')
17 ,'</DOCUMENT_TITLE>');

25 dbms_lob.writeappend(tlob, LENGTH('<PAGE_TEXT>'), '<PAGE_TEXT>');
26 dbms_lob.writeappend(tlob
27 ,LENGTH(nvl(c2.texte, ' '))
28 ,nvl(c2.texte, ' '));
29 dbms_lob.writeappend(tlob, LENGTH('</PAGE_TEXT>'), '</PAGE_TEXT>')

Changing input buffer size slows down simulated device?!?

hi,
my basic problem is having a 200279 buffer overflow.
for a quick fix I increased the buffer size using DAQmxSetBufInputBufSize, but now the signal coming from the simulated device is much slower.
how can it be?
thanx!

Hi,
Buffer overflow errors occur when data is written to the buffer faster than it is being read off of it. Buffer underflow errors occur when data is being read off the buffer faster than new data is being added. In order to avoid either of these, a general rule of thumb for NI devices is to acquire around 1/10th of a second of data. For example, for a sample rate of 100 Hz, set samples to read at 10 samples.
Is it possible for you to decrease the sample rate?

Will I increase my Buffer Cache ?

Oracle 9i
Shared Pool 2112 Mb
Buffer Cache 1728 Mb
Large Pool 32Mb
Java Pool 32 Mb
Total 3907.358 Mb
SGA Max Size 17011.494 Mb
PGA
Aggregate PGA Target 2450 Mb
Current PGA Allocated 3286059 KB
Maximum PGA Allocated (since Startup) 3462747 KB
Cache Hit Percentage 98.71%
The Buffer Cache Size advise is telling me that if I increase the Buffer Cache to 1930Mb i will get a 8.83 decrease in phyiscal reads (And its get better the more I increase it)
The question is .. can I safely increase it (In light of my current memory allocations) ? Is it worth it .. ?

Two things stand out:
Your sga max size is 17Gb, but you are only using about 4Gb of it - so you seem to have 13Gb that you are not making best use of.
Your pga aggregate target is 2.4Gb, but you've already hit a peak of 3.4Gb - which means your target may be too small - so it's lucky you had all that spare memory which hadn't gone into the SGA. Despite the availability of memory, some of your queries may have been rationed at run-time to try to minimise the excess demand.
Is this OLTP or DSS - where do you really need the memory ? (Have a look in v$process to see the pga usage on a process by process level).
How many processes are allowed to connect to the database ? (You ought to allow about 2Mb - 4Mb per process to the pga_aggregate_target for OLTP) and at least 1Mb per process for the buffer cache.
Where do you see time lost ? time on disk I/O, or time on CPU ? What type of disk I/O, what's the nature of the CPU usage. These figures alone do not tell us what you should do with the spare memory you seem to have.
A simple response to your original question would be that you probably need to increase the pga_aggregate_target, and you might as well increase the buffer size since you seem to have the memory for both.
On the downside, changing the pga_aggregate_target could cause some execution plans to change; and changing the buffer size does change the limit size on a 'short' table, which can cause an increase in I/O as an unlucky side effect if you're a little heavy on "long" tablescans.
