Heat affects performance of my server

hello
I have a windows server 2012 with 4 gigs of ram in a place that is not datacenter
ie no refrigeration, this affects the performance of my server ..

Are you asking if a warmer temperature will affect the speed at which the processor runs?
In general, the answer is no. However, you should talk to your hardware vendor to see if they have implemented any thermal controls. Modern server processors have the capability to run at different speeds, and this can be changed via software.
The fast they perform, the warmer the CPUs get. Your vendor may implement logic that says if a system reaches x temperature it will force the CPU to run at a lower speed. You need to ask your server vendor if they have implemented anything like this.

BULK COLLECT LIMIT affects performance in any way?

Hi,
I want to know whether BULK COLLECT LIMIT affects performance in any way?
How does one decide what limit to keep?
is there a oracle recommendation on the same?

I agree with Bonist that you should read Tom's article but I am going to disagree, to a minor extent, with Tom's comment about 100 rows.
When developing with BULK COLLECT I always add a parameter to stored procedures that is used to tune the limit clause Then when the code goes to unit testing, and at the beginning of integrated unit testing, the value is varied and the results graphed. For final testing the parameter is dropped. The number I hard code for production is the value at the left side of the top of the bell curve.
What I find is that 100 is sometimes the right number butI have one app I developed recently where 50,000 was the right number (11gR1). As with almost everything Oracle the best answer is always that "it depends." In the case where 50K is the best solution the server has 32G of RAM, and everything processed is an SMS message averaging only 79 bytes.

Is there a way to achieve ST05 does not be affected by Work-load Server ?

Hi
When we run Trace Analysis (ST05) the time of program execution is affected by work-load server. We can run the same program with same selection screen data severel times, and the trace results different for each one.
If i'm trying to optimize Selects, i can not see if really the time was reduced because the trace depends when i run it, how much work has the server.
Is there a way to make the ST05 give me the real seconds dedicated to program without be affected by work-load server ?
Does this event can be managed by some Basis ST05 configuration ?
Regards
Frank

Hi Frank!
In short: no!
If you have a multiprocessor-system, then the trace might get time information from different threads - so the base for the time measurement is not reliable. This is also indicated by the red-lights in tips&tricks.
Also of course general workload is <i>really</i> influencing your (identical) select - so the correct runtime can differ every time it's executed.
If you make performance adjustments, concentrate on using indices - this you can see by the explain function and look for the slowest parts first - not important how much time this needed exactly.
Also different where-clauses based on different user inputs will influence selects - but much more than the workload. Maybe defining more mandatory fields and an optimization of the select-path will bring better results than tuning one statement.

Christian

Does daisy-chaining a Belkin Mac-compatible hub affect performance?

I've had a 7-port Belkin hub plugged into my 13" Macbook and before that a 15" Powerbook for several years and have been pretty satisfied with it. I'd like to get a new one and connect it to the original (or vice-versa). Does anyone know if doing that would affect performance of any kind? (Upload times, wireless mouse interference, etc.?) Belkin doesn't seem to have anyone who knows much--the rep I talked to didn't even know Belkin made a hub that works with Mac.
Thanks for any information anyone has.

That makes sense. My old hub is 2.0, so it should work with the new one I want, which is also 2.0.
I don't know how much power I might ever be using at one time. have a wired keyboard and wireless or USB mice, and at times I probably download something into my printer buffer while at the same time backing up to an external hard drive or flash stick. But I don't think I'd ever be doing more than that, and the present 7-port hub seems to have no problem handling jobs requiring 4 ports at once.
I really just wanted the second hub because the present one is at the back of the desk behind the dictionary (cord is too short to reach the front!), and I'm tired of trying to insert devices into the USB ports without knocking the dictionary off its stand. I figured that plugging a second 7-port hub into the first one would allow me to have a hub at the front of the desk and give me a few extra ports as a bonus. If you have a better idea, I'd be happy to hear it! Meanwhile, thanks so much for the information, and the fast response.

Convergence - AlphaImageLoader affects performance

According to the YSlow FireFox extension, Convergence's extensive use of AlphaImageLoader is a detriment to performance.
Grade F on Avoid AlphaImageLoader filterThere are a total of 73 filters
* https://.../iwc_static/layout/css/main.css?...
* https://.../iwc_static/layout/themes/default/default.css?...
The IE-proprietary AlphaImageLoader filter attempts to fix a problem with semi-transparent true color PNG files in IE versions less than Version 7. However, this filter blocks rendering and freezes the browser while the image is being downloaded. Additionally, it increases memory consumption. The problem is further multiplied because it is applied per element, not per image.>
Do they really affect performance? If so, what would happen if I stripped them out of the css files?

According to the YSlow FireFox extension, Convergence's extensive use of AlphaImageLoader is a detriment to performance. The AlphaImageLoader filter is only applied when the client is using IE6 i.e. all of the AlphaImageLoader CSS rules have a class name of ".dj_ie6".
So removing these rules is not going to improve the speed of non-IE6 browsers and will cause IE6 images to have non-transparent backgrounds.

How low can mac mini storage capacity go before it affects performance?

I have 15 GB left on my hard drive, how low can it go before it affects performance and I welcome any recommendations on how I can best expand storage space.
Usage: I use my mac for word and excel docs, but I store a number of images and graphic files, but I don't use any designer software.
Thanks,
Sq1mac

Welcome to Apple Discussions!
There's no one answer to the question of how much free space you really need to keep on your drive before performance and system stability begins to suffer, but with 15Gb left at the present, you will only be reaching that point if you are doing things like burning disk images (because macOS grabs drive space to store the image) or syncing with MobileMe.
In your situation I'd be careful not to go below 10Gb free.
Expanding storage space is very easy. Buy an external drive with either USB2.0 or Firewire interface (firewire is better but more expensive) and connect it to your system. If the drive isn't set up for a MAc, it can easily be partitioned and formatted using Disk Utility on the Mac, and you are then ready to use whatever capacity the external has - including moving any or all your files, music, photos etc to the external if you wish or need to. Just about any external, even models which appear to be for PC/Windows use only, will work perfectly well on a Mac - you don't need a 'Mac compatible' drive.

Does frequent garbage collection affect performance

Hi,
I have written code in a filter for all the servlets in the application.
Depending on the servlet requested I set the objects to null after
it has finished its work.
My question is that since the filter will be executed each time a
servlet is requested,could it result in affecting performance ?

I'm writing off my own experience so take my advice with a grain of salt.
The battery is known to 'degrade' when reaching excessive temperatures. Apple recommends keeping the temperature between to 32 degrees Fahrenheit and 95 degrees Fahrenheit.
I used to game heavily on my phone which would get hot. After a year, I noticed that I had to fully charge my phone 3 times a day in order to make it through a day with light usage. Also, I noticed that the phone would die when the battery percentage display would be at all sorts of numbers, 37%, 43%, 7%, and sometimes stay on 1% for 5 minutes while running a processor-intensive game.
After taking my phone to the Apple store for a diagnostic, Apple confirmed issues with the battery. There's no way to know if having my phone stay hot for long periods of time damaged the battery or if I just had a defective battery.
My recommendation is if you know you will be gaming heavily to take the case (if you have one) off your phone and to be in a cool environment to try to keep the phone from getting too hot.
Your battery failed not because of temperature, but you used it up. The battery is spec'd for 400 full charge/discharge cycles. If you fully drain the battery every day that's about 14 months. If you drain it more than once a day that's less time. The phone has a thermal protection circuit that will shut it down if it gets hot enough to damage anything. And actually Lithium batteries do not degrade at higher temperatures. Electric cars and plugin hybrids use the same battery technology (like the Tesla, Chevy Volt, Prius Plugin, Nissan Leaf) and they run much hotter than iPhones. And last 10 years.

Duplication of movieclip will affect performance?

hi
i have doubt on duplicating movieclip.
i have a movieclip, it has a huge codes inside in it. when i duplicate this movieclip into 5 means, all the duplicated movieclip will work based on its repective code inside. this will affect the performance or not.
any suggestion pls.

In terms of filesize it should not affect performance. In terms of processing, anytime you increase the amount of simultaneous processing that is occuring you can affect performance. It probably wouldn't matter too much if you had your code once in the main timeline for all five or each has its own set of code. If the amount of processing is the same, the performance should be the same. You should try it with different numbers of them and see if performance is grossly affected.

Will Servlet Filters affect performance

Hi,
is it true that Servlet Filters will have impact on Web application performance by slowing things? any suggestion plz..
Regards,
A.

The question "Will X affect performance" is almost always bogus.
It only makes sense to compare the performance of two code bases that perform a certain predetermined task. In your case, you could make your question not be bogus by comparing an application that uses servlet filters with another application that performs the same functions in a different way. You don't seem to be prepared to do that.

Does DBMS.JOB affect Performance

Dear experts
Please tell me Does DBMS.JOB affect Performance.

Can you detail what performance you are talking about.
DBMS_JOB is simply a scheduler, whcih you can use for your repeated uattended job initiation.which is nt going to impact the performance.
Probably the actual Job if intensive can hit your performance.

Cool'n'Quiet affecting performance?

Hello,
I noted something in my K9A2 Platinum and AMD Phenom 9950.
First of all I had it oced to 2.7 (x13.5) and Cool'n'Quiet enabled.
Well, due to a bug in Everest 5.02 sensor driver, I can't read correctly the CPU clock because this program show even speed like 700 MHz when I'm doing heavy task. As I thought it was impossible, I ran CPU-Z and this showed the correct values (1300 MHz when idle and 2700 when doing heavy tasks).
The issue is the following: Today I was converting an .avi video to DVD using a program that is optimized to use only two cores. The strange thing I noted is that processor was at 1300 MHz and only few times it changed to 2700 MHz. However voltage was at 1.3 all the time until conversion finished. Of course that if I disable CnQ or I choose another energy plan, speed is 2700 even when idle.
This program (ConvertxtoDVD) used about 50% of my processor.
Does CnQ affect performance? I thought that a conversion like that is a heavy task and it can benefit from 2700 MHz instead 1300 MHz, or CnQ is smart enough to know when an app. benefit or not from a higher speed?
Thanks!
I want to say than one of the better thing of MSI is its forum

Thanks for the suggestion.
Based on the results I can confirm that CnQ affect performance, quite disappointing. I don't know the difference between the CnQ of Athlon 64 X2 vs. Phenom, but in Athlon the processor change speed to its maximum immediately when I started doing heavy tasks instead of Phenom changing its speed to max only when 4 cores are being used and only some times when using less than 4 cores.
Here're results:
With CnQ ENABLED:
CPU Score   3347
CPU1 - Red Valley   1,160 FPS      CPU Tests
CPU2 - Red Valley   1,545 FPS      CPU Tests
With CnQ DISABLED:
CPU Score   3622
CPU1 - Red Valley   1,209 FPS      CPU Tests
CPU2 - Red Valley   1,737 FPS      CPU Tests
What do you think? Is a mobo, CPU problem or a performance hit like this is normal?
Quote from: Aramus8 on 14-July-09, 05:55:06
On some programs you will get a performance hit with Cool & Quiet enabled. Run 3DMark06 with it on and then with it off and you will see the performance hit. Most programs you will never notice.

How to Improve the Performance of SQL Server and/or the hardware it resides on?

There's a particular stored procedure I call from my ASP.NET 4.0 Web Forms app that generates the data for a report. Using SQL Server Management Studio, I did some benchmarking today and found some interesting results:
FYI SQL Server Express 2014 and the same DB reside on both computers involved with the test:
My laptop is a 3 year old i7 computer with 8GB of RAM. It's fine but one would no longer consider it a "speed demon" compared to what's available today. The query consistently took 30 - 33 seconds.
My client's server has an Intel Xeon 5670 Processor and 12GB of RAM. That seems like pretty good specs. However, the query consistently took between 120 - 135 seconds to complete ... about 4 times what my laptop did!
I was very surprised by how slow the server was. Considering that it's also set to host IIS to run my web app, this is a major concern for me.
If you were in my shoes, what would be the top 3 - 5 things you'd recommend looking at on the server and/or SQL Server to try to boost its performance?
Robert

What else runs on the server besides IIS and SQL ? Is it used for other things except the database and IIS ?
Is IIS causing a lot of I/O or CPU usage ?
Is there a max limit set for memory usage on SQL Server ? There SHOULD be and since you're using IIS too you need to keep more memory free for that too.
How is the memory pressure (check PLE counter) and post results.
SELECT [cntr_value] FROM sys.dm_os_performance_counters WHERE [object_name] LIKE '%Buffer Manager%' AND [counter_name] = 'Page life expectancy'
Check the error log and the event viewer maybe something bad there.
Check the indexes for fragmenation, see if the statistics are up to date (and enable trace flag 2371 if you have large tables > 1 million rows)
Is there an antivirus present on the server ? Do you have SQL processes/services/directories as exceptions ?
There are lot of unknowns, you should run at least profiler and post results to see what goes on while you're having slow responses.

Performance in the Server with the created report - Crystal Report 2008

Hi
      We have developed a complex report and deployed in the server. It takes more time to process and once if the report created and we are trying to expand a group/navigate different pages, the same time delay is happeneing. Sometimes it takes more than a minute which really kills the performance. My client has accepted the delay while the report is being genrated but they raise question like why it takes too much time just to display the created report.
I tried keeping the created report in Session and rebind on page_load as well stored a copy on the server and rebind whenver postback happens. Both methods working simliar and no improvement the in the performance. Is there any way to kill the time delay in this.( we have an idea like , if we store the created report at client machine and whenever postback happens just bind from client machine instead to hit the server back, Is this achievable)
Any Help would helpful to me
Thanks

Hi
What version of CR are you using?
     Crystal report 2008, I think its in subject of this thread itself. (Version 12.0.0.683)
What if any CR SP have you applied?
    No
What version of .NET are you using?
.Net 3.5 using C# technology (.Net framework 3.5)
What database are you using?
    SQL Server2008
What connection type are you using?
   We have created a Stored Procedure and connected the SP to the crystal report.
What are you comparing the performance to? E.g.; is it faster somewhere else? How much faster?
    No, we didnt compare anywhere. but my question is to avoid the delay in navigation of pages or selecting an item in the group tree. The report contains 100+ pages and client is accepting delay while creating the report but not during navigation or selection( why do the already created report takes more time(even in minutes) to render on navigation or selection and how to avoid the delay))
Define "complex report ".
Nothing complexity in the report even we have used oly less formulas(less than 5) but chats are included and used for each group( we have 6 groups in the report)
Thanks
