Hi fetch query very slow - maybe it's performance problem

Hello
I ask as below:
SELECT d.gid "Global ID"
FROM load_data d 
WHERE d.gid NOT IN (SELECT peo_no FROM ppenpart);
It is very slow. Is there any other query to extract as fast as?

Thanks in advance.

-San

You could try NOT EXISTS instead of NOT IN

select d.gid "global id"
from   load_data d
where not exists (select null
                  from   ppenpart
                  and    d.gid = peo_no
                 );

However, resultset may differ, so please test.

Several examples and explanations:

  • My projects always run very slow, what would be my problem?

    Hey everybody,

    For weeks, I worked in first and everything is still working very slow: most of the time I have to restore, even when I don't have no complex sequences (and takes forever).

    I'm not well edition 4K or something special (50 fps), but even that shouldn't be a problem with my Macbook Pro.


    My computer specs:

    -2.8 GHz Intel Core i7

    -16 GB of ram

    -NVIDIA GeForce GT 750M 2 GB

    I've tried the "'Mercury Playback Engine software only", and it does not really help. "

    Settings that I use:

    -RGB curves

    -Stabilizing Warp

    -(HLS) color balance

    Can someone help me?

  • Satellite L300-1 has 3 and WXP - computer laptop is very slow

    I installed Windows XP computer laptop Satellite L300-1 has 3.
    After portable installation is very slow, I think that the problem in the SATA driver.

    Please send me the driver SATA for Windows XP Home edition, or please give me the solution.

    Thank you

    Hello

    May I ask how you installed Win XP?
    Did you change the SATA mode on compatible in the BIOS settings?
    If yes then this problem is related to the missing SATA drivers!

    You can find the SATA drivers in the Intel Storage Manager which is placed on the page of European disk from Toshiba!

    Launch the .exe with the settings file a p

    For example (the files will be unpacked in the storagemanager folder):

    c:\downloads\iata_cd.exe - a c:\storagemanager Pei

    An accurate description, you will find in the Readme! Read it!
    Then you will get the unique file which could be included for Win XP CD using nLite software!

  • HP Elitebook 8570p - Windows XP USB very slow and the transfer rate performance issues.

    Hello. I was wondering if anyone else knows some performance issues with the HP Elitebook 8570p and Windows XP Pro - SP3.

    I get a VERY slow start, general poor performance (waiting time when opening files and programs).

    I asked to burn in tests that show that everything is good.

    USB transfer rates are VERY slow (tried all ports of a Seagate FreeAgent USB drive, which works fine on other laptops etc.) for example a 30-minute transfer a 7gig single file of the USB HD on the desktop. Only 3 minutes to do the same on another laptop.

    I think there are problems with the drivers, like Windows 7 works very well and does boot from a bootable USB.

    USB transfer rate are also good when starting from a Windows boot environment.

    I installed HP SoftPaq Download Manager, and all the drivers are up to date.

    Hello:

    I think outside of the box here... Select the Intel (r) 7 Series Chipset Family SATA AHCI Controller instead.

    If it does not, I raise the white flag.

    I think you might have some misconceptions about the work of parallel processing how and what to KEEP. You can also consult the manual of Concepts on when things go in the PGA, and when they go into the CMS and find out how to see the use of the PGA. If you try to load the buffers of the SGA by making a parallel with full table scan, it won't, because this combination uses your PGA and multiblock reads to increase performance - negative in some cases, such as yours.

    Since I updated to 30 FF, I find it VERY slow and it blocks many times a day. I was happy when version 31 is out because I thought it would work better, but it doesn't.
    The pages take forever to is to load, most of the time they will not and I have to recharge myself and then maybe they are responsible.
    Also, it crashes all the time. I noticed it's on down each time that it kind of "freeze" or when it is something big, which is not at all big load. I've never had this problem before, but have been dealing with this for months now and I'm tired instead.

    -Wait until your computer turns off and after that press the power button

    -Just after you hear the startup tone, press in and hold the SHIFT key

    -Release the SHIFT key when you see a gray Apple sign and the progress under this sign bar

    -Once your Mac boot, restart dhcpd as you usually do.

    If this does not help, follow the instructions below:

    -Stop your Mac

    -Wait until your computer turns off and after that press the power button

    -Just after you hear the startup tone, press in and hold the SHIFT key

    -Release the SHIFT key when you see a gray Apple sign and the progress under this sign bar

    -Once you see office, start a scan Disk Utility to detect and repair file system errors (remember to choose your primary hard drive)

    -Click on the disc to check, then, if requested to solve the problems on the repair disk

    -After that click on verify disk permissions, and then click Repair disk permissions

    -Once the process is complete, stop your Mac and turn it on again after 30 seconds

    Apart from this, take a look at this article from Apple and follow the instructions to reset NVRAM shown here:How to reset the NVRAM on your Mac - Apple Support

    Try resetting the system management controller: https://support.apple.com/en-us/HT201295

    I also suggest upgrading your RAM.

    I hope this helps!

  • My iPad WiFi Air video very slow loading same 3 full bar signal

    My iPad WiFi Air video very slow loading same 3 full bar signal... Any suggestion?

    Should I send to AppleCare or upgrade to the latest version of iOS?

    Yes, update to the latest version, 9.3.1. Also here are a few general suggestions for problems of Wi - Fi. Suggest you start at the top and down, maybe they'll help...

    (1) perform a forced reboot: hold the Home and Sleep/Wake buttons simultaneously for about 15-20 seconds, until the Apple logo appears. Leave the device to reboot.

    (2) resetting the network settings: settings > general > reset > reset network settings. Join the network again.

    (3) reboot router/Modem: unplug power for 2 minutes and reconnect. Update the Firmware on the router (support Web site of the manufacturer for a new FW check). Also try different bands (2.4 GHz and 5 GHz) and different bandwidths (recommended for 2.4 to 20 MHz bandwidth).

    (4) change of Google DNS: settings > Wi - Fi > click the network, delete all the numbers under DNS and enter 8.8.8.8 or otherwise 8.8.4.4

    (5) disable the prioritization of device on the router if this feature is available.

    (6) determine if other wireless network devices work well (other iOS devices, Mac, PC).

    (7) try the device on another network, i.e., neighbors, the public coffee house, etc.

    (8) to restore the device (ask for more details if you wish).

    (9) go to the Apple Store for the evaluation of the material.

  • Backups Time Machine very slow on 2015 MacBook Air

    Associated with a topic of discussion between a few days ago (two MacBooks, 10.11.4, a fast Time Machine backup and a very slow), I start a new topic with new information that seem to show it is a problem more general and not related to Time Machine networks.

    Here's the situation:

    • A 2015 MacBook Air, 10.11.4, 8 GB / 512 GB, has extremely slow performance of backup Time Machine, taking 40 hours for the first 300 GB backup and incremental backups for a long time as well
    • TM performance is essentially the same whether on the network (wired Ethernet) or a USB3 external disk
    • When you back up to disk USB3, I confirmed that the information system shows that the port is configured as USB3, not USB2 (nothing else is plugged into the USB port)
    • Tests of bandwidth I/O gross (using dd and iperf) show no problem; the network reached 110 MB/s bandwidth, written network managed at 50 Mbps, external USB3 HD written work at 40-50 MB/s (write hard drive speed limit)
    • 3 other Macs of various ages from 2009-2014 on the same network have no problem at all do backups Time Machine Network; a backup complete first on a 2011 MacBook Pro 500 GB takes 5 hours or more than 10 x faster than the MBA problem
    • Time machine network uses a Linux server running the latest Debian and Netatalk 3.1.8 and the connection is via a USB3/Gigabit adapter, no WiFi, and iperf tests with this arrangement shows 900 MB/s of throughput of the server.  In all cases, the Time Machine and external time Machine Network USB HD have the same symptoms.
    • The problem with MacBook Air is configured the same as the MacBook Pro 2011, which she replaced "daily driver", possible
    • This problem was shown by the MBA since his unboxing conversion, taking 20 hours for his first backup once Setup initially.  Incremental backups now take several hours, leading to interrupted incremental backups and, I believe, databases corrupted backup triggers new full backups that take today the 40 hours.

    Using Terminal Server and iostat, Console, etc, I see that there is significant activity e/s for the backup drive on the order of 20 to 40 MB/s for long periods on the MBA during the TM backup, but during that time the average declared backup size as shown in the window in the console and TM is growing by only 5 GB/hour.  This occur even if the backup will the external drive or a network drive. This seems to mean that the I/O bandwidth to and from the disk hard external, only 1/600 contributes to the progress of the backup.  I am sure that there is overload of certain checks and other tasks, but not to a 600-to-1 ratio.

    I tried to disable the limitation of the I/O of low priority as shown here: http://apple.stackexchange.com/questions/212537/time-machine-ridiculously-slow-a close-el-capitan-upgrade, that helps a bit (maybe 20-30%), but not by a factor of 10 for others.

    I have gone through a number of the Time Machine of Pondini troubleshooting steps, but he found nothing corresponding to these symptoms.

    The only thing I can conclude is that Time Machine, the application or configuration, on this specific MBA, is down. (A single thought that I wrote this to the top that I have not tried: the MBA and the time MBP running VMware Fusion and have a file of 50 + GB VM; on the MBA that is not excluded from TM backups while on the MBP is)

    Does anyone have advice on what to watch next?  In all cases, only one key would be why it seems that only 0.16% of all the bandwidth I/O to the backup drive seems to be actual data backup.

    Once again, three other Macs, all running the same 10.11.4, back to the Time Machine Server perfectly and have for years.  Only this new MBA glue as broken out, either to a network drive or an external hard drive USB3.

    (A single thought that I wrote this to the top that I have not tried: the MBA and the time MBP running VMware Fusion and have a file of 50 + GB VM; on the MBA that is not excluded from TM backups while on the MBP is)

    What happens when you exclude it as the MBP?
