How to improve HDD reading speed?

Hi!
I have the 7200 rpm type of HDD as stated in my profile, chosen because of the extra speed compared to the 5400 rpm one. I haven't got space for a Mac Pro so I'm stuck with this laptop. I've examined disk utility and it seems as if I am able to use RAID 0 on this machine. I'd like to have striping on my system partition and read about FireWire 800 and the Expresscard slot. What are my options when it comes to improve the speed of harddrive reading?
Any suggestions welcome!

How to improve the response speed

Dear Consultants,
In BI 7.0 EP Environment, displaying 40000 detailed records wasted 3 minutes, this speed is slowly.
How to improve the response speed ?
Please give me some proposals and methods to solve this question.
Thanks a lot & Best Regards

Hello,
3min. is not so bad for 40000 rows of data. Firstly you can analyze where the time spent is it olap or DB. you can use RSRT for analysis.
Then,
1. Create aggregates
2. Use caching and precalculation
3. check 'Use Selection of Structure Elements' from properties of query in RSRT
4. Remove unnecessary calculations from query
5. remove unnecessary rows. try to make them free characteristics.
6. If there is unused data in infocube, you can archive this data.

How to improve this query speed ?....help me

How to improve the query speed. Any hints can u suggest in the query or any correction. Here i am using sample tables for checking purpose, When i am trying with my original values, this type of query taking longer time to run
select ename,sal,comm from emp where(comm is null and &status='ok') or (comm is not null and &status='failed');
Thanx in advance

How to improve custom protocol speed?

Hi
I used RMI to get an array of shorts from server.
Then I thought that using RMI for transferring arrays of primitives
is not a good idea, that is why I decided to create my own protocol for
transferring data.
The other goal to implement my own protocol was to show a data
transferring progress to user.
I thought it was not easy to do it with RMI If I am wrong let me know
how to do it with RMI please :)
Unfortunately my protocol implementation works slower than RMI.
Here goes code for simplified version of my protocol.
Can anyone suggest what I should do to make it work faster.
Protocol is designed to transfer data provided by FooData from
FooDTPServer to every connected FooDTPClient.
The protocol works as follows:
FooDTPClient connects to FooDTPServer and sends code that indicates
that it is a client(all codes are described at DTPCodes).
Server replies with code that indicate that it is FooDTPServer.
Client asks server for data.
Server sends a length of data it is going to send and then sends the
data.
If client wants more data it sends new request for data.
If it wants to close connection, it sends special code.
If client sends wrong code at any state of conversation with server
the server closes connection.
Here goes implementation of protocol.
// file DTPCodes.java
public class DTPCodes {
* client sends it to server to at the begin of conversation.
public static final byte HELLO_IM_DTP_CLIENT = 1;

A lot to quote up there, but as for moving away from RMI, since you have the code and in my personal estimation there's really not THAT much overhead for non-remote return types, is there a reason you wish NOT to stay with RMI for this if you have that ability?
I would however suggest also GZIPping the short[] array and other data as that will save on xfer time, either in RMI or your own personal protocol.

Macbook Pro 1.1 how to improve read/write speed

Hello,
I am looking to improve the read/write performance of a 2006 2.16 Intel Core Duo Macbook Pro with 2gb RAM (the max), that I use on a specific job in a specific workflow.
In the workflow there are three retouchers using three different MBPs and transferring files via Ethernet network to a fourth MBP (the one in question) which is used as a dropbox, if you like.
So the MBP in question has no applications running. Files are saved to it and opened from it and saved back to it.
How can I improve read/write speed on this MBP under these conditions?
Would installing an SSD be the answer? Or is it really a processor issue and there's nothing to be done? I figure RAM doesn't really come into it, but in any case 2GB is the max this model can accept.
Many thanks in advance.

An SSD would definitely improve read/write speed. However, depending on capacity needed, are you sure you want to sink the money into this machine? Start here:

How to improve speed of data acquisition? Help needed urgently.

I want to convert analog signals to digital signals and simultaneously perform some search on the data acquired and this whole process has to be done continuously for few hours.
So I tried writing two programs in Matlab, one acquires the analog data and converts it to digital and saves the data in small chunks on hard disk (like file1, file2, file3,...) continuously. The other program performs the search operation in those chunks of data continuously. I run both the programs at a time by opening two mat lab windows.
But the problem Iam facing is that the data acquisition is slow. As a result I get an error message in the second program saying that
"??? Error using ==> load
Unable to read file file4.mat: No such file or directory."
Iam unable to synchronize the two programs. I cannot use timers in search program because I cannot add any delays.
Iam using a NI PCI-6036E ,16 Bit Resolution ,200 KS/s Sampling Rate A/D board.
Should I switch to some other series such as M series having sampling rate of the order MS/s?
Can anyone please tell me how to improve the speed of data acquisition?
Thanks.

Need to spell this out a bit more..
But speed via 2.4ghz to the TC is restricted by Apple to max 130mbps link speed.. much slower actual transfer.. latest TC and laptops can do 450mbps on 5ghz but you need to be up close.. so place the TC near the device using it.. and force 5ghz connection by using a different name for 5ghz network.

How to improve spreadsheet speed when single-threaded VBA is the bottleneck.

My brother works with massive Excel spreadsheets and needs to speed them up. Gigabytes in size and often with a million rows and many sheets within the workbook. He's already refined the sheets to take advantage of Excel's multi-thread recalculation and
seen significant improvements, but he's hit a stumbling block. He uses extensive VBA code to aid clarity, but the VB engine is single-threaded, and these relatively simple functions can be called millions of times. Some functions are trivial (e.g. conversion
functions) and just for clarity and easily unwound (at the expense of clarity), some could be unwound but that would make the spreadsheets much more complex, and others could not be unwound.
He's aware of http://www.analystcave.com/excel-vba-multithreading-tool/ and similar tools but they don't help as the granularity is insufficiently fine.
So what can he do? A search shows requests for multi-threaded VBA going back over a decade.
qts

Hi,
>> The VB engine is single-threaded, and these relatively simple functions can be called millions of times.
The Office Object Model is
Single-Threaded Apartments, if the performance bottleneck is the Excel Object Model operation, the multiple-thread will not improve the performance significantly.
>> How to improve spreadsheet speed when single-threaded VBA is the bottleneck.
The performance optimization should be based on the business. Since I’m not familiar with your business, so I can only give you some general suggestions from the technical perspective. According to your description, the size of the spreadsheet had reached
Gigabytes and data volume is about 1 million rows. If so, I will suggest you storing the data to SQL Server and then use the analysis tools (e.g. Power Pivot).
Create a memory-efficient Data Model using Excel 2013
and the Power Pivot add-in
As
ryguy72 suggested, you can also leverage some other third party data processing tool
according to your business requirement.

How to improve my mac pro speed

how to improve my mac pro speed

You don't have a Mac Pro, you have a MacBook Pro. There is no way to make it faster because you cannot replace the CPU with a faster one. You can add more RAM to help improve performance when you have a lot of concurrent applications running or use memory hungry applications. You can add a faster disk drive to improve the speed of I/O. You can sell it and buy a faster model.

How to increase disk read and write speed after installing new SSD (2009 Macbook Pro)? Why not as fast as advertised?

Hi everyone,
I just installed a Crucial MX10512 GB SSD into my 2009 Macbook Pro. It's definitely much faster, but the read and write disk speed is around 200 Mb/s for both versus the 300-500 Mb/s that the SSD advertised. Any ideas as to why? And is there anything I can do to make it faster? Before I installed it, it was between 80-90 Mb/s.
Specs:
- currently have about 460 of 511 GB of storage available
- am using 2GB of memory
- running on 10.10.2 Yosemite
Thanks!

Sorry for all the questions - I'm not a Macbook wiz by any means!
You could make a clone of your internal OS onto an external disk. Hopefully you already have a backup of some form
A clone is a full copy, so you can boot from it. It makes a good backup as well as being useful to test things like this.
Carbon Copy Cloner will make one or you can use Disk Utility to 'restore' your OS from the internal disk to an external one.
Ideally the external disk is a fast disk with a fast 'interface' like Thunderbolt, Firewire 800 or USB3. USB2 can work, but it is slow & may effect the test.
You connect the clone, hold alt at startup & select the external disk in the 'boot manager'. When the Mac is finished booting run the speed tester.
Maybe this one…
https://itunes.apple.com/gb/app/blackmagic-disk-speed-test/id425264550
Test the internal & compare to the previous tests
A running OS will do the following on it's boot disk…
Write/ read cache files from running apps
Write/ read memory to disk if memory is running low
Index new files if content is changing or being updated
Copy files for backing up (Time Machine or any other scheduled tasks)
Networking can also trigger read/ write on the disk too.
You may not have much activity that effects a disk speed test, but you can't really be sure unless that disk is not being used for other tasks.
Disk testing is an art & science in itself, see this if you want to get an idea …

Simply knowing that it's about twice the speed would be enough to cheer me up

Gt70: after installing windows 8.1 read speed is slow :(

Hi guys,
I got my MSI GT70 with the 128*3 SSD + 1024 HDD configuration. It can only get a read speed around 740 MB/s in hdtune. but before i install windows 8.1 (i install it from scratch reformating the whole system) the read speed was around 1100 mb/s ! I searched in another forum and found some one said "MSI representative told us our test unit was actually underperforming on the SSD front.".
So does anyone know how to config the raid correctly to get back the 1100 MB/s speed?
Many many thanks!!!

Quote from: loki5100 on 19-December-13, 01:58:06
Many thanks !
yes it's show that dragon edition is a little more faster than the i7 4700mq
me only 1250 MB/s average rate ...
wait that you computer is running several hours and try again the test ... it's here that i saw the speed go down to 750 mb/s :(
I don't have the extreme, so I have the same cpu as you. The difference could be mainboard optimizations but mostly sure the hard disks. Mines are plextor.
But anyway 1250MB/s is not slow at all. Maybe slower as expected, but not slow for sure

How to improve ojspc jsp compile performance?

Does anyone have any advice on how to improve the performance of the JSP pre-compilation utility (ojspc)?
We are using Oracle 10g OC4J containers.
Our situation is that we're attempting to add support for Oracle AS (we're currently on Weblogic), so I'm just getting started learning about it. In our development process we aim for sub-5 minutes clean builds, including recompilation of JSP files. Currently our 838 JSP pages take about 27 minutes to translate and compile using ojspc and jikes, but only a few minutes with Weblogic 8.1's jsp compiler.
Here are my initial experiences with ojspc:
* ojspc by default always translates JSPs, regardless of whether they've changed (that is, regardless of whether the .java and .class are up-to-date)? Is this really true? Is there an option to ensure it performs up-to-date checks?
* Also, it only supports batch compilation when your JSPs are packaged in a WAR? And even when doing this it extracts the entire WAR (which is 20Mb in our case) before starting. I couldn't find an option to make it recursively descend a JSP directory hierarchy and compile each JSP. In development we don't package as a WAR.
Here is what we've done to begin to speed things up:
* We wrote a wrapper to descend our exploded JSP tree to decide which JSPs need recompiled based on timestamp of generated .java and .class files, then invoke the ojspc compiler with the names of all those JSPs.
* We use ojspc with -noCompile to translate to .java only
* We then use Jikes to compile all the .java files
But at this point, its still a 27 minute process for 838 JPs. Previous experiences with other JSP compilers (HP Bluestone, previous-generation Weblogic) is that they are often slow because they re-parse each TLD file for every defined taglib in every JSP page. Does anyone know if this is true of ojspc?
Unfortunately we use a technique whereby every taglib is defined in every JSP page by a static include page to ensure consistency of prefix. So there are over a dozen taglib directives in each page, possibly resulting in over 1000 TLD parses.
Has anyone shared this experience or have any advice on speeding things up?
Thanks in advance,
Tim

Hi,
We need more details. If you'll reply with the create table command and the query, we can give a better answer.
I would look for the following:
- Make sure you're doing a full scan of the table.
- Consider running the query in parallel (/*+ full (tab) parallel (tab 8) */) using a hint.
Since you are grouping the results, consider sorting in memory:
alter session set sort_area_size=XXX. Value depends on the table size and your hardware.
Let us know how it goes, and additional hardware details.

How to improve preformance on Control Center?

Hi all!
Does anyone know how to improve performance on Control Center? Its very slow when openning and refreshing
We are using OWB client 11.1.0.6.0 and OWB Repository 11.1.0.1.1
The performance was improved when we cleaned up the deployment and execution repository, buy it took almost 3 days to finish, the script used was purge_audit_template.sql
If anybody knows any other way to improve the performance will be great
Thanks Yuri

Hi
I also find that purge audit template script very slow. I'v found another one that is much faster and speeds up the control center.
Before running this script you must log in as repository owner and run stop_service.sql (found in owb_home\rtp\sql). After the script, run start_service.sql
