How much can too many imports slow inititialization down?

How much can too many imports slow applet inititialization down?
I have seen our company's sorce code for some huge applets they have written. In many, many cases, the imports at the beginning of each file are written something like this...
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import javax.swing.*;
import javax.swing.border.*; 
import javax.swing.event.*;Only certain portion of these imports are actually used. Does this sort of thing really impact the applets loading speed? I know it will obviously take at least a little longer but will the user even notice?

You are not actually importing the classes, but rather making the names of the classes available.

  • How much is too many?

    Have an iPad 16gb.
    Curious - At what point and how many Apps does it take for the device to be affected and slow down?

    Ask 300 people, get 300 answers .....
    I rarely have more than 4 or 5 apps in my recents tray at any one time. But you can bet your bottom dollar that my browser - and it doesn't matter which of the five that I have I am using at the time - will crash on me every day - day after day - 3 or 4 times a day. I seem to have particularly bad luck with the iPad internet experience. When I use the Mercury browser - and it has done this since day one - I constantly get the low memory warning - even if I have closed all apps and have just restarted the iPad.
    That's kind of a bummer for me because my iPad has become more of an mobile internet toy and email reader than a work machine. That's OK - I had no problem spending the money and taking the chance to see what I would get out of it because I wasn't quite sure what I would be using it for but I knew I really wanted one.
    There really is a point to this and it is that no one has any way of knowing for certain how many is too many. As I have told you - I can run one solitary app and crash with great frequency. It's just something that only you can find out on your own as you continue to use the device.

  • Can too many Photos slow down a Mac Pro?

    Hi, I have atleast 100,000 photos on my pc, would this many photos slow down a 2.66GHz quad core mac pro with 6 gigs of memory? thanks

    I have 60,000. I use non-boot drive of course for data. Some people have huge music and video libraries of 2TB spanning 2-3 drives on stripped RAIDs.
    Mac Pro and OS X really likes RAM, and the base for DDR3 8-core is to have 6 DIMMs and I'd go with 6 x 2GB, either Apple or 3rd party RAM, then add 3 x 640GB drives (WD Black Caviar). Stripe two, even if you partition it as 400GB each. http://www.barefeats.com/nehal04.html
    And keep the boot drive to OS and applications primarily.
    A nice guide:

  • How Much is Too Much?

    Hi everyone,
    I have recently been using my macpro more and more for high-def video work. I usually leave it on 24 hours a day as at night I set up a batch of files in compressor to run over night. Essentially, all my CPUs are maxed almost all the time. I am wondering if this could become a problem? I have read a little about average loads but don't fully understand what they mean. Mine are: 8.60, 7.58 and 7.42 and I am getting pretty high temps on my CPUs, power supplies and hard drives (about 44C, 54C and 39C average respectively). Am I pushing this thing too hard? How much is too much? Please see my system specs below.
    Thanks a lot!
    ~ Philip

    Don't let the drives get to 70C! they can take 50C safely. Memory and graphics are more of a concern. The cpu will protect itself.
    smcFanControl can insure that your fans stay above the default minimums, which is worth taking a look at (freeware).
    Fluctuation in temps between extremes can stress a hard drive and memory.

  • How to fix: Too many Primary Partitions ? G770

    Hello,
    I am trying to install PuppyLinuxSlacko.5.4 from a LiveUsb to a unallocated-Partition in my Lenovo-G770 Laptop, Win7 . 
    My G770 shows that I have two disks: C:\  and  D:\ .
    But the Using (Linux) GParted program shows there are 4-Primary Partitions already (see pic GParted01.png below) . 
    http://www.vmars316.com/ShowMe/GParted01.png
    And when I try to Format the Unallocated Partition, I get an Error Msg (GParted02.png below) .

    Pls, How to fix: Too many Primary Partitions ?

    I've been told that to try and fix it in Linux is too risky .
    I set up the unallocated 20gb partition.
    Can I just merge it into the 29gb Extended Partition ?
    If I did merge, How would I access it ? Which Partition is it an extension of ?
    I am on thin ice here, and would rather fix the prob in Window7 , because I am brand new to Linux .
    Here is the PartitionsDetail using AomeiPartitionAssistant -note the differences:
    http://www.vmars316.com/ShowMe/AoemiPartitionWindows.png
    Is there a way to tell what's in the partitions , especially the two 29gb partitions and the 14gb partition ?
    Worst case: Is there a way to reset my 'Lenovo G770' computer back to factory settings under win7 ? 
    I think I'll add this Post to the Win7 Forum, since I hope to fix it via Win7 .

  • How much can you customize Professional level storefronts?

    I know that you need to be an Enterprise user to have completely customized storefronts, but how much can you customize Professional user storefronts? What do they look like? Most magazines I've seen are Enterprise level

    With a Professional account, you cannot customize the storefront. If you create a subscription app, you can specify subscription tiles and indicate with subscription durations are available, but that's about it.

    Hi,
    Are we sure that a voice memo can only be 35 minutes long? I only ask as I'm about to start Uni and was quite keen to use the voice memo feature to record lectures (which are definitely longer than 35mins).
    Just to test (as I've never really used mine before) I might leave mine running tonight and see when it cuts out/stops.
    BTW, what's iTalk....and how do I get it???
    Thanks :o)

  • Kernel Memory limits. How much can it usefully use?

    I just wanted to check something.
    Obviously the Linux kernel can handle a lot of memory, but the question is how much can it usefully use before it needs to be specially compiled?
    I need to build a server to clean email, and because it is very very busy, (well the last one was and so is its stand in) it will need 4GB of RAM as an absolute minimum but I would like to put in 8. If I go for 8, do I need to rebuild the kernel?
    Kind regards
    Benedict White

    If you install Arch64 and use the normal kernel package -- no. You won't touch the RAM limit for some decades to come.

  • How we can monitor while import request in production system?

    dear friends,
    will you please explain me
    how we can monitor while import request in production system?
    and
    what are the things we have to monitor during the transport?
    thanks
    regards
    zaheer

    Hello Zaheer ,
    I would always recommend to check that you have the latest transport tools, tp and R3trans in use in the system to avoid import errors.
    Check with
    tp -v
    R3trans -v
    if either are more than around 4 months old, I would strongly recommend to download the latest for your release from the SAP service marketplace. This avoids needlesly encountering issues that have been resolved in more recent patch lebels of these tools.
    During the import, it is important to check the contents of the directories
    usr/sap/trans/tmp
    and
    usr/sap/trans/log
    that they are being continously updated which shows import is progressing.
    Most important, keep checking the latest entries in the alog, uloag and slog to see which phases and trasnports are currently being imported.
    If a transport fails, check these logs and the latest ones updated in usr/sap/trans/log for further details on the failure.
    If there is an error please NEVER manual run any commands wihtout contacting SAP and having them analyse the issue.
    When opening a message, be sure to include the latest alog, ulog and slog, along with the last few files most recently updated in usr/sap/trans/log and if possibel open an R3 connection to the import system.
    Best regards,
    Paul

  • Does too many apps slow down iphone's performance?

    does too many apps slow down iphone's performance?

    31 apps is nothing. I have 130 apps XD. Then again, I'm using an iPhone 4S which has more RAM compared to the 3GS. RAM is everything when it comes to speed. To use the app switcher, press the home button twice quickly and a list of your recently opened apps will appear. Then hold down on any app and all the apps will go to wiggle mode (like they do when you're deleting apps. Now, simply tap on the red icon that appears at the top left corner of any app you don't want running in the background. This will free up RAM and should make your phone faster.
