Expression in SSRS Slowing down Report Rendering

An expression in my report is making the report to run very slowly. The
expression, set in a Row Column Visibility Property is like so:
=IIF(Parameters!View.Value = 1 AND (Fields!PastVal.Value = 0)AND(Fields!DatePay.Value = 0) AND
(Fields!Line.Value = 0),True, IIF(Parameters!View.Value = 2 AND Fields!TaxPaid.Value = "N",True, False))
Now this expression returns the right result. The problem is that it makes the report run very slow. To test it, I took off the expression and reports are displayed in less than 3 seconds but with the expression on, report takes over 50 seconds to run.
Any help on this? Thanks.

Hi Zionlite,
After creation of that column just go to the row visibility property and use newly created calculated column directly as shown in below screen.
I kept both tablix one is normal having expression in visibilty condition and another with calculated columnto verify the result. when I run the report result is like below:-
I also attached the code for reference.

Calling a multi value parameter seems to slow down report

Hi
Nearly all of my datasets use a multi value parameter at present which from testing seems to be causing a long delay.
If I change the dataset to not call the parameter and manually enter the values in this works quicker, the only issue being if I need to add an additional value I need to then do it on multiple datasets rather than one parameter.
A way around this I thought was to do the below which doesn't seem as slow as my original method.
To try better explain I have done this
SELECT
Practice.ibvSalesByJob.JobType
FROM
Practice.ibvSalesByJob
WHERE
Practice.ibvSalesByJob.JobType IN (N'1', N'4', N'5', N'8', N'12', N'17', N'40', N'45', N'60')
I then have a parameter which has default values > dataset > JobType
The actual dataset shown in the report then shows
WHERE
Practice.ibvSalesByJob.JobType IN (@ABSJobs)
Does this make sense or is there a better way of doing what I am trying to do?
Is there a known issue with Report Builder 3.0 and multiple parameters?
Any help/advice appreciated.
Cheers
Cheers Chris

Hi Chris,
According to your description, when you create a multivalued parameter, then specify its values from a dataset, the report is running slower.
In Reporting Services, all datasets within a report will be retrieved when running the report. In your scenario, if you specify the parameter values from a dataset, it’s possible to cause performance issue. If parameter doesn’t have too many values, you
could specify the values for the parameter with specified values in Report Parameter Properties.
Besides, in Reporting Service, the total time to generate a report include TimeDataRetreval, TimeProcessing and TimeRendering. In your scenario, you could run the report in report server, check the table
Executionlog3 in the ReportServer database to analyze which section take much time. Then you can refer to this article to optimize your report:
Troubleshooting Reports: Report Performance.
If you have any question, please feel free to ask.

Does Adobe Dynamic Links slow down the rendering process ?

Hello everybody,
I have a question concerning Adobe Dynamic Links.
This is my problem :
I work on After Effects. I have a composition that is rendered quite fast. (almost in real time...)
But when I open the linked comp in Premiere Pro, it lags as hell. Maybe 2x, 3x slower.
So I'd like to know why Adobe Premiere Pro is slow, while After Effects is fast ?
Is this normal ?
What can I do about it ?
Thanks,
Regards.
Josef Retsnbergïk

Todd_Kopriva wrote:
Because you wouldn't want After Effects to take over all resources from Premiere Pro when you are working primarily in Premiere Pro and just using After Effects as a helper application through Dynamic Link.
But I primarly see this when I'm exporting via AME. This pulls in not only PPro, but also AE, etc., all through DL. And everything comes to a halt whenever a lower third shows up to be rendered, because AE serializes the process. So my eight core processor becomes a one core processor until that seven seconds or so of footage goes by. And that, is silly. Sorry to have to call it what it is. And it's a serious performance problems that Adobe should address and fix. Truly.
I guess my "real" question is, why is this an Abobe problem in the first place? This is, or at least should be, an OS resource allocation and scheduling problem. Same as memory allocation should be handled by the OS's Virtual Memory system and not by Adobe. I was taught that problems like this were the whole point behind the a multi-tasking scheduler. Yeah, I know -- back then we had Unix and VMS, and today we have Windows and OSX. This is... progress?

Internet speed slows down when connected via airport express

Internet speed slows down when connecting via airport express. When connecting directly via the timecapsulethe internet speed is ok, when connecting via the airport express the speed slows down.What can I do to change that? Any suggestions?

Turn off the AirPort Express completely as a test, and move your computer very close to the location of the Express.
As I said before, the Express can only extend the bandwidth (speed) that it receives from the Time Capsule, so the speed that you see there with the Express powered off will be the fastest speed of which the Express is capable.
The Express will make the signal go further when it extends....but it will not make the signal go faster.
A good location for a device that extends wirelessly is a point that is about half the distance from the Time Capsule and the general area that needs more wireless coverage.
If you locate the AirPort Express too far from the Time Capsule or there are more than a couple of walls in the signal path, the signal will be very slow by the time that it reaches the Express....and the Express simply extends a signal that has already slowed down significantly.
If you already have the Express located about half the distance between the Time Capsule and general area that needs more wireless coverage, how many walls, ceilings or other obstructions are there in the signal path between the Time Capsule, the AirPort Express and the area that needs more coverage?
Often, due to obstructions, it is just not possible to achieve good performance when you try to extend a network wirelessly. The solution is connect the AirPort Express to the Time Capsule using a wired Ethernet connection.
There is virtually no signal loss with this type of connection, so the Express can be located exactly where it is needed and it will produce a much faster wireless signal in this type of setup.

Report Rendering Very Slow With RDLC

I am running into some horrible performance with running reports as .rdlc's
The reports themselves are fairly straightforward, save for some column and row groupings in matrices. If I have one simple column group, things run pretty quickly. If I add one or two more groupings, things slow down incredibly!
I've been doing some research and have found that several people have experienced the same problem as I.
http://prologika.com/CS/forums/p/1272/4541.aspx#4541
Unfortunately, I don't have the option to test out performance of the reports against a "real" SSRS installation. And the data source I'm working with is actually a C# dataset versus an actual SQL Server database.
We're currently running on Windows Server 2003 and are using .Net 4.0
Has anyone else experienced the same issue, and if so, how did you ultimately resolve/work around the issue? Amazing that the performance between rdlc and rdl's could be that drastic!
The developers have mentioned creating a field for each possible value for a field. For example, there is a top level group called "Plan" and a sub-group called "Unit". These are just two of the fields we are grouping on for column groups.
There are possibly 30 different plans, with possibly up to 6 units. So essentially, there would be up to 180 columns in a table. We would then need to write expressions to hide any columns/groups that have no value. Not a smart option...

Hi Robinson,
Thank you for your question.
I am trying to involve someone more familiar with this topic for a further look at this issue. Sometime delay might be expected from the job transferring. Your patience is greatly appreciated.
Thank you for your understanding and support.

Report makes slow down

I have some problem of performance due to the report generation.
If I do not use "on the fly reporting", performance are ok, each item of my loop takes the same time. But I have nothing in the report.
If I use "on the fly reporting", performance are bad, ecah item of my loop take more and more time which becomes inacceptable. On the contrary, my report is ok.
Is possible to have a report without disturbing and slow down the execution of the sequence ?
Thanks a lot for your support.

Hey sfl,
The short answer is NO.
Basically on the fly reporting is being updated everytime a step that records results gets executed. So you have to store that in memory. How many steps do you have? If you have a bunch of steps and your report is really long then you will see performance drop dramatically.
So you have to choose one or the other unfortunately.

Report Slow Down

We have a report that used to produce a 1000+ page pdf in
about 2 minutes. It has gone to producing a 200+ page report in
about the same amount of time. No change to the data, database,
report or environment, it just suddenly slowed down and nothing
seems to be able to make it go back to decent performance on large
record sets.
Server reboots don't help, any ideas or thoughts would be
appreciated.

Hello
I followed some Donald's suggestion and went through some explanations he's given on its web site to try to figure out how could I speed up the database 10g since we migrated from 8i to 10g.
Here are default values in our 10g influencing the COST BASE OPTIMIZER
OPTIMIZER_FEATURES_ENABLE=10.2.0.1
OPTIMIZER_MODE=ALL_ROWS
OPTIMIZER_INDEX_COST_ADJ=100
I launched his script below provided to see time waited between full scan table
('db file scattered read representing by the c3 row and the
sequential read representing by the c4 row)
select
sum(a.time_waited_micro)/sum(a.total_waits)/1000000 c1,
sum(b.time_waited_micro)/sum(b.total_waits)/1000000 c2,
sum(a.total_waits) /
sum(a.total_waits + b.total_waits)
) * 100 c3,
sum(b.total_waits) /
sum(a.total_waits + b.total_waits)
) * 100 c4,
sum(b.time_waited_micro)/sum(b.total_waits))/
(sum(a.time_waited_micro)/sum(a.total_waits)
) * 100 c5
from
dba_hist_system_event a,
dba_hist_system_event b
where
a.snap_id = b.snap_id
and
a.event_name = 'db file scattered read'
and
b.event_name = 'db file sequential read';
there is the output of the script
C1 C2 C3 C4 C5
.002438964 .002888595 24.6526611 75.3473389 118.435332
So the time waited for full scan(c3) table is most faster than index sequential read(c4:index probe)
I changed the parameter OPTIMIZER_INDEX_COST_ADJ and OPTIMIZER_MODE
alter system set OPTIMIZER_INDEX_COST_ADJ=20 scope=both;
alter system set OPTIMIZER_MODE=FIRST_ROWS_1000 scope=both;
I lauched aigain the script above, but the output shows the result below
C1 C2 C3 C4 C5
.002438964 .002888595 24.6526611 75.3473389 118.435332
this output isn't different than the first one, so does this mean that INDEXES are not well designed or WHAT ELSE?.
Wich parameter could I enable or change to decrease the C4(index sequential read wait time?
Thank you for your help

How to use string as an expression in SSRS reports

Hello all,
I have created a SSRS report in which I have used a tablix and a single dataset (ds_test)
Now the dataset use t-sql and is calling a table in which has data as shown below:
What I am trying to do is to use this as an expression inside the cell of the tablix. But when I run the report It give me:
But It should show the result as "True", I know it is taking this as a string but is there any way so that we can use this as an expression in the report
NOTE: We cannot use this directly in report , because this is generated dynamically and should always present in DB tables only
Thanks in advance
Pankaj Kumar Yadav-

So your table has a varchar column with 'iif(1=1,True,False)' in one of the records ?
yes
Pankaj Kumar Yadav-
You wont be able to pass a value from db like this and use this as an expression inside SSRS.
If you're using SQL 2012 you can exec this expression using dynamic sql and then show return value as is in a SSRS report.
SSRS is a presentation tool with limited scripts and it cant do any query processing against database. that part have to be implemented using t-sql query on backend (dataset)

Rendering speed is slowing down during process, almost up to freeze

Hello there!
First of all, I'm a new person to After Effects. I bet I just doing something wrong, but anyway I would like to ask an advice how to fix my issue because googling such subject won't solve it.
The point is following:
I rendering 120-minutes long video for YouTube. It almost static with no effects, just with a few simple fade-in/out transitions on couple of layers. You can find an example of such video on YouTube by this link: Daniel Lesden - Rave Podcast 056: guest mix NitroDrop (Israel) - YouTube (for some reason, specifically this video was rendered successfully previously).
Process is going very well at first, 1 minute of playback rendering for about 30 seconds, so first hour of the video rendering for 30 minutes.
The problem starts at about 70% of overall progress: it start to slowing down, and then goes to 1 frame rendering for 1 second. As you can imagine, it's a pain for such long videos, it will take a days to finish last 20-30%.
Composition and render settings are following:
Size: 1280 x 720 px
FPS: 30
Format: Quicktime
Codec: ProRes 422. I've also tried: Animation, Photo JPEG, another ProRes and even H.264, but outcome was the same.
Output module settings screenshot:
Multi-processing settings:
On this point I have to say that I've tried many different options with amount of CPU, RAM or with Multi-processing option turned off completely, but in the end it all was the same.
After Effects version: CC 2014 (still on trial version, but it shouldn't be a problem since Adobe don't have any limitations for trial versions as far as I know).
Computer and OS information:
Any advices please? I'll very appreciate every possible solutions.

"open AE preferences>General then move to the bottom tab and set AE to purge every 10 frames or so"
— I've set this parameter to 10 as suggested, and here are the last render queue results:
First 60-minutes video rendered superb good for 1 hour 17 minutes.
Second 120-minutes video goes really badly: it took 8 hours to render about quarter due to error. Here is what I found in the error log: "There is an error in background rendering so switching to foreground rendering after 246 frames completed out of total 216000 frames. (26 :: 142)".
Later I've tried to render second video again, and it was great almost till finish: 1 hour 45 minutes has been rendered for less than an hour. But then it suddenly slowed down (as described in the original post), so I had to stop it. I installed Memory Dig and "optimized" memory before rendering and once during process, but it didn't help. In the end I just rendered last 15 minutes of the video (with no issues) and just merged it into 120-minutes long file using Video Joiner. Pretty sad method, although.
On a third attempt everything was fine until rendering stops by a new error in popup window: "After Effects error: internal verification failure, sorry! {could not find itemframe we just now checked in}".
So the original problem still wasn't solved yet unfortunately.

Can logic express slow down or change the key from playbacks like the program "Amazing slowdowner"?r

Hello,
I'm a new member and I'm actually trying to work with garage band to record voice and playback. Can "logic express" Vs. 8.0 slow down or change the key from playbacks like the program "Amazing slowdowner"? This is a programm wich costs 50 US Dollar and I want to decide if i buy it or not.
What is the hgreatest different between "garage band" and logic express 8.0? Who can hepl me, which is the right thing for me. I find it difficult to find out which effects are the best only to record my voice with playback.
Thanks for your advices.

If you want to slow down the audio why not download a program from ABRSM called Speedshifter- its free and is very good. you could export the audio from Logic and open the MP3 file with speed shifter. I think speedshifter may also have the ability to alter the pitch as well. I use it for Flute practice- its very useful !

Will using the old express slow down my network?

I want to setup a network without being connected to the internet, with an Extreme N connected to an external drive, AppleTV, and Airport Express for music.
1. If I use the old Express that is not running at N speed, will this significantly slow down my network?
2. If I setup my network with the old one and later upgrade to the new one, is it a big deal to delete the old one off the network and add the new one?
Thanks.

You can have an N network with a G subnetwork. You connect the WAN connector of the G router to a LAN port of the N router. You set the N router to work only at N, that is without support for G networks. Let the G router handle those.

Does new Airport Extreme slow down when used with Airport Express?

Maybe this is self-evident.
If get the new Airport extreme and use an old airport express to extend it, will signal slow down to the old speed?
Does the AE have a greater range? Perhaps I don't need the Express to extend.
I live in NYC and there are so many signals in the air. It seems like having the additional airport helps keep me connected.
Thanks.

The airport express is g technology not n technology, so it will be at least as slow as your old network. Also, I'm not sure but I think the the range will be a bit longer than with the old g system, but does not have the full potential of an n system.
I've set up my new system but none of my machines are n capable. I extended the system using my old expresses. The speed of the system is no greater than what it was before the n.
I bought the system to upgrade my technology because everytime my Applecare runs out, I get a new computer which isn't too far down the road. I've purchased an Apple TV which will also work better with the n technology when I upgrade. It's either buy it now or buy it later. I'm also hoping that some third party like Belkin will develop a PCIX card to provide n technology to those of my computers that aren't currently n capable. I'm sure there is many like me out there.

Slowing down the music in Logic Express

Is it possible to slow down music without bringing down the pitch, like amazing slow downer does?
Thanks, Frans

Slowing down the music on the same pitch is easy...when you know it. I found that when you check the box "follow tempo" the tempo of the song can be adjusted in the transport window. And then the music will be slowed down on the same pitch to the preferred speed. Very useful when you have to study on a Charlie Parker solo. Now I can make a start to actually understand what the man was really doing.

Application Express slow down

I launched my first APEX application a week ago - before I went on my vacation. At that time, the response time was extremely fast - no matter if the user was trying to navigate between pages and tabs and to log in or log out. When I came back this morning, I found that the application was slowed. Then, I tried to see if the slow performance was related to the shared memory by clicking the same record several times for several records. What I saw was that the first time I called the record it was slow. When I called the same record after the first time, it became fast - because the record was cached. This showed me that the problem might relate to the shared memory. However, since the database is very small and the total SGA is already 300MB (Shared Pool: 148MB,
Buffer Cache: 136MB, Large Pool: 4MB, Java Pool: 4MB, Other: 8MB), it doesn't make sense to keep adding memory to it - especially the database server is now shared by 5 individual databases. I wonder if, after a while, some logs or sessions in APEX need to be "manually" purged in order to increase the performance.
Thanks.

The performance issue of APEX is strange because, at the very beginning, the performance of the application increased extremely right after I changed the total SGA from 198MB to 300MB (with about 160MB for buffer cache) - every page or tab was immediately loaded when clicked. It lasted for about 2 weeks. Then, since last couple of days, it slowed down significantly. It was no use even after I again increased the total SGA from 300MB to 400MB and re-started the database. This doesn't make sense because the performance should be consistent. Also, it is a very small database with only 5 users.
Has anyone encountered the same issue?
Thanks.
