Performance increase from 4 to 8 gigs

I'm running a 27" iMac 3.06. It came with 4 gigs, but I'm considering going to 8. I'm not a gamer, but I do run a lot of simultaneous apps, and I occasionally need to run Windows 7 on Parallels. Anyone have any experience on performance increase? Also, anyone have experience with Crucial vs. Apple RAM?

No performance increase from doubling ram

I upgraded the RAM in my Mac Pro from 4 to 8 GB of 800 MHz DDR2 FB-DIMM RAM and although I see in About This Mac that the RAM is installed, I'm not noticing any perofrmance increase. The vendor who sold me it- MemoryAmerica- sent a replacement and it's the same. When doing tasks in the finder like scrolling through images using the preview window, it gets increasingly slower until I'm constantly getting the spinning beach ball and "Waiting for Finder"...shouldn't 8 GBs of RAM on a MacPro be sufficienct for these simple Finder tasks?
One possible issue- I booted off my installer CD and tried to run Apple Hardware Test and it keeps getting hung on that- it starts the process but then freezes....what is my problem? Thanks.

Also, it is sometimes a good idea to test and run AHT and your system with just the new RAM properly installed.
It may be your hard drives or something else or storage arrangement is the bottleneck.
Ideal for 2008: 8 DIMMs. And in some cases mixed sets of different RAM (size, vendor) don't work properly together - as in a pair of 2 x 4GB and mixed with 4 x 1GB.

Gaming Performance Increase from Late 2011 MBP to 11 or 13 MBA 2013?

I have a Late 2011 MBP 13,upgraded with 256 GB SSD and 6 GB RAM.
I play mostly CS:S, SC2, WoW, D3 and that's about it.
I would like to be able to move into SimCity (After Aug 29 Launch Obviously), and perhaps DCUO and The Old Republic (VIA BootCamp)
Would I see a nice jump with the haswell chips in the MBA 2013 model?
If so I might jump, if not I am ok here right now, running wow at low with 30+ FPS.
Just curious, thanks for the advice!

The Late 2011 13-inch MacBook Pro has got an Intel HD Graphics 3000 GPU, and the Mid 2013 13-inch MacBook Air has got an Intel HD Graphics 5000 GPU.
The MacBook Air will work better with graphic tasks, but both of them are not ready for heavy use.
If you want to play games like those ones, the best thing you can do is to get a 15-inch MacBook Pro, which includes a quad-core processor and a NVIDIA GPU which will work correctly. The difference will be very big compared to the Mid 2013 MacBook Air.
Also, the MacBook Air is not ready for games. It overheats quickly, and high temperatures damage it. If you get the MacBook Air, don't set high values in games, and make sure that the games you want to play support integrated graphic cards

Not able to extract performance data from .ETL file using xperf commands. getting error "Events were lost in this trace. Data may be unreliable ..."

Not able to extract performance data from .ETL file using xperf commands.
Xperf Commands:
xperf –i C:\TempFolder\Test.etl -o C:\TempFolder\BootData.csv –a process
Getting following error after executing above command:

I changed page size file but its does not work for me.
Any one have idea, how to solve this problem and extract ETL file data.

I want to mention one point here. I have total 4 machines out of these 3 machines above

Hi,
I consider that you can try to use xperf to collect the trace etl file and see if it can be extracted on this computer:
Refer to following articles:

SELECT call performance increase through archiving...

Hi all,
Short description : SELECT call performance increase through archiving records that satisfy a particular criteria like a cut off date. Is there any way i can intercept a select call on the real table and make it return records from the real or archive table based on the criteria (dates) issued in the call.
Long description:
I've been given the job of decreasing the execution time of a select statement on a particular database consisting of a few lakh records. the premise is that not all of these records need to be searched through for a normal query. only audit reports need access to the entire table. the additional premise is that the separation of tables should be transparent to the program (no changes can be made to the code). given these premises, i've been toying with some ideas that have not helped me out.
* Read about Fine Grained Auditing that kind of allow a trigger on select which would change the sql query to select from either the real or archive table( not sure if this will work either). But my production system uses oracle 8i. so no FGA :-(
* thought of create/replace a view that would restrict the rows based on a cut off date. but this would require code changes to make select calls on the actual table whenever an audit is required.
Is there any way i can intercept a select call and make it select from one/ both of the tables based on the criteria (dates) issued in the call.
any other suggestions on this kind off transperant archiving is welcomed.

Do your queries have a WHERE clause? If so, and the table is partitioned by date, Oracle can implicitly eliminate all the older partitions.
If your queries are not currently limiting themselves to a particular date range, you could also create a parameterized view with sys_context. Without changing your application, you would need to ensure that there were different users for different roles (i.e. an audit user would have a login trigger that set up a different context than a login trigger for a normal user). If you can make small changes to your application, you could add a call to set the context whenever you want to change roles.

Problem: slow connection. I have an iMac (2007) running on Mac OS X 10.6.8. I just had my internet speed increased from 1 to 3 Mbps but my connection slowed down considerably. Do I have to change any setting?

Problem: slow connection. I have an iMac (2007) running on Mac OS X 10.6.8. I just had my internet speed increased from 1 to 3 Mbps but my connection slowed down considerably. Do I have to change any setting on the computer, and how?

One possibility is that you may need to "Upgrade" your Cable /DSL Modem if you have an older unit. ISP's that provide your Internet service in recent years have been switching over from DOCSIS 2.1 version Modems to DOCSIS 3.0 version Modems, which handle the new higher data streaming speeds the ISP's are offering. I would suggest you call your ISP's Technical Support and inquire about this possibility.

Why has my Latency (Ping) increased from 20ms to 3...

Got BT Infinity installed (FINALLY, after over 12 months of them putting it off every 3 months) but this was due to a problem in our village I believe. Anyway, I am right at the end of my line and 5KM or so from my local exchange, I was only getting 2.3 meg max on ADSL and 0.8 meg upload, on BeThere (02) broadband. My pings averaged 18ms to BBC.co.uk (London/Local Servers).
Now, had infinity installed last Tuesday, and expected upload and download speeds according to Infinity of 42.1MB download and 6.5MB upload. Fastest speedtest yet was 48MB on speedtest.net and fastest upload was 6.7MB.
Now two questions:
1. A few days ago, I was receiving speeds on average of about 42-44MB in speedtests, now as of yesterday morning, this has dropped to around 38Meg. My Upload is about the same at 6.2meg.
2. THE MAIN QUESTION - Why has my Latency increased from about 20 (18-23ms on average) to 30?
Every speedtest I do now for the last 2 days, is coming back with a ping of 29-33ms which is a sudden increase of 10ms. I'd like to know what may have caused this, as I game and I know a better ping is crucial for gaming.
Can anyone shed some light here?
Thanks

Well as you can see, I've attached you a screenshot of my tracert command results, what do you think?
Well from that tracert you can see the increase isn't all down to interleaving, the first hop after the router is only 15ms, that's the interleaving, it's after this hop that the ping times increase to near 30, so in your case the ping increase is all down to how bt are routing your connection over their network.
Here's my tracert to the same website, routing is different for me and hence the better pings, also the lower interleaving depth on the second hop is also helping of course

Performance tuning from Basis point of View ?

Hi,
Can anybody help me in doing the performance tuning from Basis point of view.
What all parameters are involved in it and what are the values need to be initially assigned and what all factors need to be kept in mind.?

Accessing Performance Data from third party Application

I have a requirement where in I have to fetch the performance metrics from SAP through a Java application. I know there are some RFC's available in CCMS module. But the customer is not interested in CCMS module.
So, is there any way to achieve it?
If anyone had come across this situation, please let me know.
Thanks in Advance,

Performance increase on macbook pro 2012

I own a 2012 baseline Macbook Pro mid 2012 model.
I am planning on upgrading the existing 4GB RAM to 16GB Crucial memory.
Also, I am planning on upgrading the existing HDD to a Crucial M5 SSD.
My question is if I upgrade, will I see a signifigant performance increase? Beacuse As of now it has trouble opening iPhoto with 110GB pictures on it.
Please answer ASAP.
Thanks,
Sam

The SSD will increase your MBP performance on boot. shutoff and heavy weight applications. On web browsing and the like, there will be little change.
16 GB RAM will allow you to run your MBP more efficiently if you have a lot of applications open, Speed is always governed by the CPU.
To give you an idea what to expect when you use a CPU intensive application, look at the benchmark diagrams here illustrating the addition of RAM and a SSD:

Important performance metrics from Tivoli, MOM, etc. into Oracle database

Hi,
I'm brand new with all of this stuff. I'm trying to grab performance data from a bunch of performance tools (MOM, Tivoli, Load Runner, custom client tools, etc.) and import it into one big file in an Oracle database (the performance data would have to map). Then, ideally, I'd like to be able to link that data up to Excel somehow and make graphs from it. Is this feasible? Where can I go for information to help me out with this?
Thanks!

Everything you've written is wrong. Well not just wrong but horribly wrong.
Here are my thoughts in no particular order.
1. Since are brand new you should push yourself back from the keyboard and educate yourself before you proceed. Is there anyone in your organization you can ask for help?
2. Your entire concept around "import it into one big file" is not a complete non sequitur it is essentially impossible. A relational database such as Oracle stores information in logical segments called tables. You need to design a table with columns that correspond with your data and comply with normalziation rules.
http://www.psoug.org/reference/normalization.html
3. Unless you are not under any governmental restrictions with respect to auditing and compliance you've go not business ever taking data out of a database and putting it into a toy like Excel. Get a report writer such as one of the tools Oracle sells or Crystal Reports, or Cognos, etc.
Where can you go for information? I'd suggest you start with the Oracle DBA who is managing the database. Buy him or her lunch and ask for help. Then go to your manager and ask for training.
My apology if this sounds harsh but sitting here reading this was roughly equivalent to watching two cars at 100kph heading toward each other on a one-lane road.
