performance SqlDataAccess vs QtSql
In some discussions I read QtSql will be faster than SqlDataAccess
Here are my tests of reading data (SELECT) - INSERT will follow later
Initially I open the database:
mDatabase = QSqlDatabase::addDatabase("QSQLITE");
mDatabase.setDatabaseName(dataPath(dbName));
if (mDatabase.open() == false) {
const QSqlError error = mDatabase.lastError();
qWarning() << "Cannot open " << dbName << ":" << error.text();
return false;
}
qDebug() << "Database opened: " << dbName;
my table has 100 k with TEXT 9 lines and an INTEGER, the PRIMARY KEY is a column of TEXT
objective:
SqlDataAccess afer to start the database, I create the connection: then I read all the data, loop through the result and use QVariantMap to fill the QObject *. fillFromSql will do this way: Read data lines: 9 seconds ----------- QtSQL Same as above: read all the data and loop through result to create a list of the QObject fillFromSqlQuery (request, record) he's going to do it this way: Read and process the lines: 57.4 seconds so in this case QtSql seems to be 30% slower - but maybe I'm doing something wrong. made a few final tests, inserting data in bulk (100 382 records) and tried to use blocks of data first scenario: BEGIN TRANSACTION See INSERT INTO with blocks of 1 k, 5 k, 10 k, 20 k rows END OF TRANSACTION conversion and inserting pieces of 10 k a 1 second fast, pieces of 5 k, or 20 k almost same, slower 1 k blocks second scenario: make the FINAL as BEGIN TRANSACTION - INSERT INTO - TRANSACTION with pieces of 1 k, 5 k, 10 k, 20 k rows 5 k, 1 k more slow and 20 k even as first scenario pieces of 10 k now 1 second faster conversion and insert now 16.5 seconds compared to 24.9 dry SqlDataAccess is to use the QtSql 33% faster THX Simon Hain motivatiing me to spend SqlDataAccess to QtSql. Tags: BlackBerry Developers Function execute() SqlDataAccess resulting in the memory not freed calls When I do a lot of updates or written to my locally stored database, it seems that little memory is not released after calls to the execute() function. It is an example of a call that I do: I am currently adding a part without head to my request, and when I do on 500 + database updates, I got up above the limit memory 3 MB, which will stop the application. Of course, it is a major problem, but I wonder if it's just because of me something wrong or if it's actually a problem with the class SqlDataAccess itself. Does anyone have any suggestions? Use QtSql. Crashing apps and the slow performance since the installation of macOS Sierra Hello Im a user of long date Mac but displays the first time that I was pretty happy with everything that on my macbook pro for the past years... until I installed Sierra a day ago.

I'm not sure I'd worry about the plane crashes - it is listed as beta software I've just updated to the latest version of Sierra. I thought I had read somewhere that SMB was preferred over the AFP in Sierra and that performance would improve. I don't see any improvement. My results are so radically different, I thought that I post to see if anyone can tell me why my performance SMB is so catastrophic? I have a Mac Pro (non-cylindre) on a home network wired gigabit. Synology DS412 + NAS running 4 disks in RAID 5. I mounted it my my Mac using the basic option "Connect to Server" in the Finder and typing "afp://server:share" and "smb://server:share" for testing. Both were mounted and tested separately, which means I am disconnected from the AFP before Assembly and test SMB. I used rsync with some verbose options to copy a 1.5 GB file in order to see the speed and get a transfer of the statistics. Here are the stats to transfer the file to AFP: [josh@jeter /joshtmp]-> transfer diskimage. ISO/Volumes/FILES/tmp /. Building file list... 1 file to examine DiskImage.

It seems that Apple still did not set their "quick and dirty" dose for such Badlock described in this thread: El Capitan 10.11.5 update slow SMB (bug) If you believe that your network is protected from man-in-the-middle attacks and the bug Badlock, then you can disable the client for signature.

Geek of multicore benchmarks is too less to another macbook even type (me 294). It's my macbook: multi-core on 6000 landmarks https://browser.primatelabs.com/v4/CPU/337791 https://browser.primatelabs.com/v4/CPU/337570 This is another of the same type (me 294): multi-core on 12000 landmarks I reboot before benchmarks, I don't know why? GeekBench is a crude tool that is useful for computers compare configured identically. Means "Identically configured" quite the same hardware running identically configured systems with identical changes, as appropriate. As says Geekbench works best when it is the only application running. Comparing the performance of your Mac to others requires the abandonment of all other open applications in addition to process who can have no user interface. To identify the processes that are running on your Mac in order to see how they affect the activity and performance of your Mac, use the activity monitor: use the activity monitor to your Mac - Apple Support. Reinstall 10.7.5 to help performance Late 2009 iMac 10.6.1 when new, now running 10.7.5 with 8 GB of memory and 2 TB of disk running My Mac worked slowly for a while. Check memory, CPU etc. in the activity monitor shows no reason for this. I want to reinstall the OS X 10.7.5 menu utilities in OS X, but I have no USB or disk with 10.7 on it. Given a stage to try and BONE cleaning is to wipe the drive, then I suppose I'll have 10.7 on some media. I believe that the steps would be: 1. all save, deauthorise apps 2 restart the Mac in recovery mode 3 erase/format the disc extended journaled format 4 reinstall OS X Who would bring back me to 10.6.1 that came with the Mac, so I have to upgrade to 10.6.8 then 10.7 as soon as I got it on a media, and then work my back to 10.7.5 So, how I 10.7 or y at - it an easier way to get my Mac running as it was when new? Thank you. Frank. With 8 GB of memory and a HD 2 to (assuming that it has enough free space available on it) and your Mac must perform well. Mac in general do not need 'clean up', but they have a third-party software installed that can cause performance problems. Before you go to the backup, erase, re - install, upgrade to Lion road you can download and run EtreCheck and post the contents of his report here. Can anyone identify if there is a probable cause of software to your problem: My email has been hacked and used to send Spam. I have to perform a virus check, or simply change the password? Do not install or run an anti virus app. How do you know that your email has been "hacked"? It is a common practice for spammers to forge an envoy from the e-mail address. It may be that your email address has been misused. There's nothing to do if this is the case for you. The spammer will soon pass and usurp another email address. It's a good idea to immediately change your password by email if someone would actually managed to access your e-mail account. poor performance iTunes 12.4.3.1 iTunes 12.4.3.1 worst level ever? Incomplete, burning playlists, software crashes frequently, slow dead URL, performance, WIN7 For general advice, see troubleshooting problems with iTunes for Windows updates. The steps described in the second case are a guide to remove everything related to iTunes and then rebuild what is often a good starting point, unless the symptoms indicate a more specific approach. Review the other boxes and other support documents list to the bottom of the page, in case one of them applies. The more information box has direct links with the current and recent if you have problems to download, must revert to an older version or want to try the version of iTunes for Windows (64-bit - for older video cards) as a workaround for problems with installation or operation, or compatibility with third-party software. Backups of your library and device should be affected by these measures but there are links to backup and recovery advice there. TT2 Beach ball of death as well as by the slow performance of spinning glaciers Hi people, I have been enduring the beach ball of death from a spinning some time now in the calculation of my daily life and I just can't take longer, as long as it happens little matter what I do on the Mac, and performance are slowed by the glaciers. It happens all the time. I ran several ladies of virus, including clams and none of them came with something. The problem came slowly over a long period of time. Now, however, the beach ball takes over whenever I'm on Mac to the point that I have to force quit, and then restart just to get anything done, and even then, it is not long until the ball is back and performance slows down again. Thank you in advance for any help you can provide. Please let me know if you need more information than that on my computer: With gratitude, AK Please post a report of EtreCheckof your system. We then look for obvious problems. Please click on the link, download the application and run the report. Once you have the report, please copy and paste into your response to this post. If you would like more information on what is EtreCheck, just click on the link and you will find a description of the application. It is very possible that your problem much worse by installing antivirus on your computer applications. AV apps for Mac are useless, there is no virus for OS X. Most tend to create more problems than they solve so look for developers instructions to uninstall (s) installed and uninstall them. Run the EtreCheck report after it has been uninstalled. OS X needs no antivirus, cleanup or ANY third party maintenance apps. If left alone and simply updated OS X will run well for most users for years! MainStage - loss of connectivity environment performance Hi guys,. I seem to lose connectivity between my midi controller (m-audio code 61) and Mainstage environment performance. I lost sound and the warning message on the Mainstage saying that the midi controller is no longer available. Currently, I connect via the USB port, which also fuels the midi controller. I have to disconnect and reconnect the USB cable on the midi controller or laptop and then it seems to work again. Any ideas on how to solve this problem? Try another USB cable. A premium quality cable may be the solution. The connectors tend to have a tighter fit. Another alternative is to use a power supply and a USB MIDI cable, or connect via a cable to your audio interface MIDI, if it has a MIDI. Concerned about the performance of the battery Ipod 6 Hello!. Please tell me your thoughts on this because I have no idea about. I bought a new Ipod 6 a week ago. I think that the battery is not give the performance of desire. He's dead, and after a charge noticed that drain you very quickly. So I turned off bluetooth, reduces the brightness of the screen and wifi on when I used it. I loaded 100% today, and according to the battery report used for 1 h and 50 min. (audio, videos Youtube Safari 91% Config Kindle of 5%, Home and Lock Screen 3%, 1%), time to sleep 10: 00 and 9 min. and the battery icon displays between 50 and 60 per cent of costs. It is the average or do you think the device is defective? Thanks in advance. On the basis of messages as your battery life seems comparable to others. Note that % battery is not accurate on an iPod, then you can not go this way. The test is responsible for at least 6 hours and read a video. You should get 5-6 hours East-audio/video or advertising photos in the tab 'not open' affect the performance of Firefox? From what I understand the audio Forum leaking by a tab can be cut. This means that the most important activity such as periodic updates on a page to download advertisements could also affect Firefox performance even if the tab has not been clicked. Is this true? Once the tab has been loaded, any video or audio active in this tab will have a negative impact on the performance of Firefox. In the options, you can tell Firefox to not load the tab until it is selected, but once you select the tab for the first time, the site will remain responsible. Twitter: Your account may not perform this action. Please, refresh the page and try again. Since the update to Firefox 41.0.2 I couldn't use Twitter.com. When I try to tweet, favorite, or retweet the following error occurs. Your account may be able to perform this action. Please, refresh the page and try again. There are a couple of other users who have the same problem, but it was tinkered with Mozilla and the other pending.

Here's this other thread with the DIY: Impossible of Retweet, tweet or articles favorite on Twitter, even when I refresh the page. I think there must be a setting or a question Add on. Your extensions look pretty standard, so I'm leaning towards a parameter of the problem. You could test as follows: By default, Windows hides the .js extension. To make sure that the following steps work, you have to disable this feature, at least temporarily. This article has the steps: http://windows.microsoft.com/en-us/windows/show-hide-file-name-extensions Open the settings folder (AKA Firefox profile) current Firefox help In the first table of the page, click on the view file"" button. This should launch a new window that lists the various files and folders in Windows Explorer. Leave this window open, switch back to Firefox and output, either: Pause while Firefox finishing its cleanup, then rename prefs.js to something like prefs.old. Launch Firefox back up again and it must use the default settings (for example, integrated home page). If you need to restore your previous session windows and tabs, go ahead and select restore previous Session from the history menu. Twitter works best? If so, we could try to understand the precise adjustment at fault or you could rebuild your settings. Or you can undo the change by renaming the new prefs.js to prefs.txt and rename prefs.old back to prefs.js (with Firefox closed, as you did before) and understand it through a little trial and error. Increase the performance of MAC with the SSD upgrade I have a 21.5-inch iMac model 14.1 (end 2013) with 8 GB of memory and a 1 TB drive. On this, I use some applications in memory such as Adobe CS 5.5 and VMWare Fusion 8.1.1. I have Applecare on the machine until September 2017. I often find myself running out of memory. My goto solution would be to increase the memory and replace the hard drive with an SSD. I fear, however, that this cancels my Applecare. My research indicates that while that frowned upon, I can upgrade my memory and keep my Applecare as long as it is done by an authorized by Apple, but if I do the SSD I'm out of luck for the installed components. My thought is that I can get an external SSD and move the ' WIndows 10' VM (s), as well as expand and move the swapfiles for the SSD system.» My questions are am I right about the Applecare and warranty and I plan to use an external SSD to accelerate performance and ease the work of memory constraints? I have f I have a Macbook Air in 2010 and also a 2008 iMac - both with only 4 GB of memory (you have twice as much), both running El Capitan and the two with SSD - and perform very well. The 2008 iMac used to have a rotating disc which has recently failed, with the replacement of SSD, it is a remarkable transformation with the new SSD, it seems very quickly for me. Both have Photoshop CS4, which is not used much more, but they run this software very well, as well as MS Office 2011 and other programs such as Mail, Safari, Firefox, etc. (Firefox + Photoshop together put a noticeable load on machines, in fact, but while I sometimes hear the fans come on the Macbook Air, it maintains not up very well) No slowdown) You'll be in great shape with a SSD for your newer computer. These old machines that I use have Core 2 Duo CPUs, chips relatively slow, but they seem very quickly with the SSD. You will need to check with Apple directly on your AppleCare and so that would be affected. I don't know that anyone is not Apple should trust this question. Performance of YouTube on some videos So I came across a strange bug that I can reproduce on my MBP 2014 (Iris Pro) and my iMac end 2015 (with GPU), some videos on YouTube compleltey kill the performance of tabs.

Xyz* xyz = new Xyz();
xyz->setParent(this);
xyz->fillFromSql(cacheMap);
mAllXyz.append(xyz);
}
}
