TOAD startup desperately slow?
Hi all,
I have a question for those here who use TOAD for their work. My installation freeTOAD v.6.3.11 drives me crazy last two days - it takes several minutes to start up. When finally started everything is OK and fast.
I just wonder what it can do all this time?
Thanks for hints
Petr
Hi guys,
thanks a lot for you tips. Finally I have seen a tip on
http://www.toadsoft.com/faq2.html#Logon/Logoff2
It seem to be the case - when disconnected toad starts fast without weird poking the network. My SQL*Net is OK other apps (e.g. DBA studio) work OK. I conclude that the problem is most probably in Windows networking.
Regards,
Petr

Why is Java startup so slow?
Does anyone know why Java startup is so slow? Compared to other interpreted languages like Javascript and Perl, they run much faster. And can someone get technical with me? (But without pointing me to the JVM specification, which I don't understand.) It use to take longer for me to load Mozilla0.9 than a Java applet, but now Mozilla1.3 loads faster than a Java applet.
"Connector" is a rather ill-defined way of describing
it, which is why I chose the word -- to easily deflect
further inquiries to quantify. ;>
In a slightly more specific way, on start-up JVM needs
to (not necessarily in order, 'cause I don't know the
exact order) at the very minimum:
1. Allocate memory.
2. Query OS for a minimal set of needed facilities.
3. Allocate memory. Allocate allocated memory
(internally, for use by itself and the application).
4. Map the OS facilities to Java facilities. (This is
what I meant by "connectors").
5. Allocate memory. Allocate allocated memory.
6. Set up the internal control -- security managers,
thread scheduler, gc, classloaders, calling stacks,
virtual lookup tables, etcetc.
Some of the above don't apply to applets.
Thanks for the tip on 1.4.2beta. I'll give it a try. I
assume you meant startup speed?All this is almost instant you realize. The real time it takes to start your program is that it takes much longer for Java classes to be loaded.
The startup time is proportional to the number of classes you need to load to get your program running. If you only are writing a simple, console based java program the startup time will be much less then if you load a Swing application. Swing by itself is a huge number of classes, and then you have to load your classes. So it can take awhile.
All the things you mention, every program has to do and the code that the JVM uses must be written in C or some other systems language.
One reason at least on my machine that java startup is slow is that I have a slow hard drive. On my home machine, java is much faster around twice as fast to startup, but the processor and ram are not twice as good. I think that it's because the hard drive is faster. Because most of the time it's waiting for data from the disk and the Java enviroment has the disadvantage that it's very large on disk. -
Desperately slow broadband, and getting worse!
Hi folks - the common problem here, going by the forum - desperately slow broadband.
I'm about as far from my local exchange as it's possible to get and still receive broadband. My connection is a maximum 512 kbps and has been in place for years now. My usual download speed would have been 120 kbps on a good day, and a gaming ping on 54 - 58.
This last month it's been terrible, and getting worse. Download speed dropped to 50, and this morning is 28.9. An update from the Apple website took 34 minutes for 32.9 Mb. I'm getting repeatedly booted off my gaming servers for a high ping of 300 or so; sometimes the orange light on the router flashes repeatedly before going green again.
I run two computers from the router, both on ethernet, but only one ever surfs at any time; however I used to be able to surf both - not any more. Frequent "Internet Explorer cannot display the webpage" and "diagnose connection problems" messages appear. Some webpages - for example the eBay home page - take over a minute to fully load. It reminds me of my old dial-up days.
BT Speedtests a few months back gave me a speed of 394; three days ago it was 194, this morning it did not complete the test. I'm getting very frustrated.
Struggling with less than 50 KB/s… a quarter of what it used to be.
Solved!
Go to Solution.I tried the master socket two days ago hence the recent disconnection; the end plug on my cable is a small squarish one not the longer rectangular one that the phone uses so it won't fit the master socket. Before that the router had been connected for weeks with no improvement. This problem has persisted for almost six weeks now with no return to the old faster speeds. It can't be software as I run an Apple Mac and a PC alternately through both ethernet connections (unused computer is switched off)
If gaming the game goes very slow, or freezes, I get booted by admin for high ping, and sometimes - not every time - if I watch the router the broadband light flashes orange before reverting to green again.
I've been connected for years at a good speed (for this area) but since July / august it's really dropped to the present annoying stage.

My MacBook is about a year old, and recently it became extremely slow during startup. At first it just seemed a little slow, but the past couple of days it has taken more and more time. It's now taking 5 - 10 minutes to fully come on. Once it's on, everything is fine.
I've troubleshooted in Apple Communities and tried all of the advice I've found, but nothing seems to be working. Here are the details.
My computer:
MacBook
OS 10.7.4
Processor: 2.4 GHz Intel Core 2 Duo
Memory: 4 GB 1067 MHz DDR3
Available hard disk space: 163.27 GB free (out of 249.2 GB)
What I've tried so far (in order):
1. Check startup disk - Startup disk was correctly selected
2. Use Disk Utility to Verify Hard Disk - No problems identified
3. Updated system software - no major updates (I update regularly to begin with)
4. Check System Monitor for hidden activity - Almost no activity (no other programs were running at the time); no strange users or activity
5. Check Login Items - The iTunesHelper was causing an error. I removed it and replaced it with iTunesHelper from the iTunes Package. The error was fixed, but no improvement in startup time. (Current Login items: GrowlMenu, GrowlHelperApp (Growl is up to date), iTunesHelper, Dropbox)
6. Check Library System Fonts - All necessary fonts for OS 10.7.4 are present. I haven't added or deleted fonts besides what can be installed with the OS and or with MS Office. Here the full list (long):

7. Verified and repaired disk permissions (there were several differences, they were all repaired).
I don't know what else to try. My Mac's not making any strange noises, and is otherwise running well. The only thing that I can think of is that it's been too humid in my house recently (rainy season in Japan). But the slow startup seems to be the same regardless of time of day and humidity, and if it were humidity I have no idea how to fix that. Also, none of my other Mac devices seem to be similarly affected, so I doubt that's the problem.
Any advice would be greatly appreciated!
Thank you!It turns out that my hard drive was shot. I took my MacBook to the Apple Store on Wednesday, they kept it for analysis and repair. They replaced the hard drive, and I've already got it back (Friday; less than two days in total).
Although I did check my hard disk with the disk utility, it did not identify the problem.
Some other troubleshooting advice that I overlooked was to try reinstalling my OS and to try starting up in Safe Mode. Neither would have helped in this case, but they may be useful for someone else having similar problems.
Other advice - always make sure your data is backed up and that you Apple Care coverage is up to date. -
LCDS startup is slow on Windows 7 PC
Hi,
We have been using LCDS Express in our product with Tomcat web server. We have been noticing that if we do not start LCDS Message broker
servlet from Tomcat, it starts in ~7 seconds
If we start Message Broker Servelet (and LCDS), startup of Tomcat server is taking ~1 min.
We enabled Flex Server side Logging and seeing that LCDS is taking time to bring up "rtmp channel" possibly. From the logs it seems like this rtemp channel initialization and listening to port 2038 takes about ~8-10 sec each. Another possible area where it is taking time is probably in initializing remote java classes which provide remove methods (about 75 our own java classes defined in remote-config.xml).
This we are experiencing on Windows 7 PC. Rebooting is also not solving the issue on some of this PC.
Also on some other desktops (Win XP or Win 7), sometimes it gets into this kind of slow startup issue and persistent unless we reboot the PC/laptop.
Is this known issue ? Or Is there something we are doing wrong ? services-config.xml and other config files are pretty much like the default one. Not really modified any core settings of channel or endpoints.
How do we make startup of LCDS faster ? Currently this delays our application startup due to this underlying problem and it is very fustrating for users to wait such a long time before they can use it.
thanks for your help.We only support Windows 7 in LCDS 3.1. Please try with LCDS 3.1 and let us know if you have any problems.
Thanks,

My mountain lion OS hangs like windows does and sumtimes have visual glitches like the drop down menu's are half visible. Sometimes it slows down at every point. And its just 2 months old. Please help.
Isolating Issues
Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.
Try a restart.
Run Disk Utility/Repair Permissions. Run until it reports no errors. If there is a recurring error, see the article on what permission errors can be ignored.
Disk Utility
Disk Utility Repair Permissions You Can Safely Ignore
Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.
Isolating an issue by using another user account
If the problem is still there, try booting into the Safe Mode. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart. For each disable/delete, you will need to restart if you don't do them all at once.

11.2.0.1 rac startup very slow
Stack information:
RDBMS: 11.2.0.1
OS: AIX 5.3
Clusterware: 11.2.0.1 Oracle CRS
Issue:
We have recently upgraded from 10.2.0.4 to 11.2.0.1. Prior to the upgrade, our rac clusters would start in about 5 minutes maximum time. After upgrading to 11.2.0.1, startups take approximately 45 minutes. The way that the CRS daemons start is also very strange. We start CRS on node 1, and it takes about 15 minutes for the daemons to start. After they are started, we start the daemons on node 2. At this time, the daemons on node 1 become unavailable for another 10 minutes. After the daemons on node 1 are back, the same thing happens on node 2 and the daemons are unavailable for 10 minutes. Finally, the cluster is available and runs with no issues. There are no error messages that occur during this slow startup.
I have opened a SR ticket on this with Oracle, but have not made any progress on the issue. I have also found similar issues logged on metalink, but didn't see any workarounds to the issue. I wanted to create a post on this forum to see if anyone has seen issues such as this, and if you are aware of a workaround. Please let me know if you have any information.
Thank youI would not think the CRS daemons as the primary culprits - simply "taking time" to start courtesy of some bug or something.
The CRS/OHA daemon has prerequisites. Such as opening the voting and OCR disks. Such as initialising its network end-points on the Interconnect interface. Such as IPC communication between daemons. Etc.
Take the OCR/voting disks prerequisite. The system level devices (LUNs/scsi targets/whatever) need to be created by the relevant kernel driver and these need to accept I/O.
This can only be done after the kernel driver "discovered" the actual devices via the storage fabric layer (HBAs/HCAs/etc).
If ASM is used as storage management layer, the ASM instance need to start and successfully mount these devices first.
The discovery process itself can be quite slow, depending on the fabric layer used. If for example the server crashed, the fabric layer may still have stale device entries for the LUNs for that server - and these need to reset when that server now wants "duplicate entries". Older versions of the SRP protocol (for Infiniband fabric) can be a bit cumbersome and even problematic in this regard.
Now, I'm not saying that the storage or Interconnect layers are the problem - simply that these need to be fully functional in order for CRS to start. And this is where I would start looking in your case to determine whether the prerequisites are met early/fast enough to meet CRS startup expectations. -
Mac Startup So Slow? - Mavericks
My Mac has been quite slow at starting up for a while now and it is slightly frustrating as I have multiple OS's installed and this is annoying when I am constantly needing to reboot. It normally takes around 1 min and 30 secs to boot and when I then login, it takes a futher 2 mins before I can actually use the computer without it slowing down.
It is NOT slow when using applications (ie: Chrome, iTunes, Skype and games) however the bootup and desktop loading time getting frustrating.
I have an idea that it could be the hard drive. I have a 500GB internal HDD with about 180 GB free. I also have a 1TB Seagate SSD that has quite a lot of files on it.
If anyone has any ideas or they are experiencing a slow Mac startup time, please let me know below! Thanks and hope this could get resolved!Go step by step and test.

Why is startup so slow after mountain lion upgrade?!
please someone help i regret upgrading it to mountain lion now. it was a brand new macbook pro i just bought not even a month ago and i upgraded it 2 weeks after and it takes over 1min to startup ever since... it wasnt like that before it was upgraded. please someone help. i don't want to have to do another installation of the mountain lion because il have to pay for it for another download. and i don't know and not confident enough to do a clean install anyway, whatever that is. what's going on exactly? is it a bug that'll get fixed with an upcoming mountain-lion update? it's not a matter of using space i don't think because it's a brand new laptop and has hardly anything on it. the only different thing was the upgrade and the startup was so obviously slow i know it has to be that. please someone help me fix the slow startup..

Slower Startup and Slower app launch time
Hi, ever since i upgraded to lion, my app launch times and laptop startup times have gotten much slower. Please Help!
Re:I have noticed more frequently since the 4.3.2 upgrade is a longer delay when I launch the "Settings" App.
(in response to Bruce Caucutt)
I have noticed the same response since I upgrade to 4.3.2 - I have reset the phone after shutting down all the Opened Apps, no change. Checking this out a bit more I found that the 4 sec. White screen only appears if you are Launching the Settings App first time, there after it appears almost instantly. It seems it just taking a little longer to launch in the first instance. -
Hi
My iTunes is very slow, when it starts up, i have the newest version, i have just updated.
It has allways been a problem, do any of you have the same problem, and is there a solution on the problem??How long is "forever"? I have been experimenting with startup times with my music collection (on a FW400 external drive) - on a G4 MDD it takes 60 secs to load, but on a MacBook it takes 30 secs. This even though the MacBook has much less RAM. So I am wondering if processor speed is what is being overloaded as the iTunes library file loads........ Can any of you provide actual numbers?
What Mac? How big a music collection? How long to load? Is there a pattern here? -
Boot/Startup extremely slow after Leopard installation
I installed Leopard last night and have it set up with Time Machine, etc.
I have two fairly major problems with it thus far:
(1) It takes F O R E V E R to boot. I'm talking a factor of 10 times or more longer than it was booting in Tiger. I see the grey screen with the apple logo and spinning circle for a very long stretch. Once it's up, it seems to run at fairly normal speed. But the slow boot is a real nuisance. I removed a couple of startup programs just in case they were the problem, but that doesn't seem to have been the issue.
(2) If my screensaver is on for any length of time, I can't make it go away without forcing a shutdown via the power button. Moving the mouse, hitting the keyboard, etc. just doesn't do anything.
Please help!
(If it matters, I did an upgrade install. If I need to do an erase and install to fix, can I easily get my files, etc. off of Time Machine now that it has run? If so, how?)I'm finding syslogd the culprit.
using Terminal (type: top -o cpu -R -F -s 2 -n10) I get:

It completely hangs my machine in ways like choppy finder etc.

Hey everyone,
I just bought a brand new 15" macbook pro three weeks ago and the startup speed is so slow! Whats wrong?I'll jump in with some suggestions that might or might not help -- this one-question-at-a-time approach is a bit frustrating for the lurker!
1. As a general principle, don't shut your notebook off regularly; let it sleep, connected to power.
2. But to trace the problem, try running Disk Utility's Repair Permissions application. After that, run "Verify Disk" from the same Disk Utility screen.
3. With your MBP running, load "Activity Monitor" and see what applications and processes are running. Also look at memory usage to see if anything odd is happening there.
4. Create a new user account. Switch to that account and start up into it. See if it boots any faster that way. You can delete that account after running this little experiment.
5. If none of that helps or yields clues to the problem, then I would suggest reinstalling OS X (and a Combo Update), to see if that helps.
6. If a fresh installation of OS X doesn't do anything for you, run the hardware tests included on the start-up disk, to see whether a memory or other problem might be dragging your system down.
If none of that helps, then I'd call Apple. They may have some other ideas.

Late MBP 2010: Does anyone find that startup is slower and system runs slower?
I have a late Macbook Pro 2010 and once I downloaded the new OS X I've noticed that when I turn my MBP on at start up it is a lot slower and I have to wait 30-45 sec for it to get me to the main screen plus I've noticed my programs are running a little slower. Is anyone finding the same problem? Need help...how this is just a bug that can be fixed. Any ideas or fixes?
After upgrading from Snow Leopard, you may find that older, incompatible software may cause the sort of problems you describe.
Back up your documents and everything else important to you, not that there is any reason to believe your hard disk may be failing, but the symptoms you describe may presage an impending disk failure, and you should have backups anyway.
To help determine the possible causes of this behaviour read the following. None of what follows is intended to fix anything, but it will provide the additional information required to advance troubleshooting:
Boot OS X Recovery by holding ⌘ and r (two fingers) while you start your Mac. At the Mac OS X Utilities screen, select Disk Utility. Select your startup volume (usually named "Macintosh HD") and click the Repair Disk button. Describe any errors it reports in red.
When it finishes restart your Mac and test again for operation. If it's still not behaving as you expect it should, please post the results of EtreCheck in accordance with the following instructions:
Apple Support Communities contributor etresoft wrote a very useful app to quickly gather certain system information that may help point to a cause of this problem. Go to his website, download and run EtreCheck:

Safe Mode or "Safe Boot" is a troubleshooting mode that bypasses all third party system extensions and loads only required system components. Read about it: Starting up in Safe Mode
Starting your Mac in Safe Mode will take longer than usual, graphics will not render smoothly, audio is disabled on some Macs, and some programs (iTunes for example) may not work at all.
Merely starting your Mac in Safe Mode is not intended to resolve the problem, it's to observe its performance without certain additional components.
To end Safe Mode restart your Mac normally. Shutdown will take longer as well.
