Why is Thunderbird so slow on my new computers?

My two new computers (Lenovo PC and HP laptop) both run Windows 8. Thunderbird is extremely slow on both when selecting and deleting messages. Get frequent 'not responding' messages.

Why index creation is slower on the new server?

Hi there,
Here is a bit of background/env info:
Existing prod server (physical): Oracle 10gR2 10.2.0.5.8 on ASM
RAM: 96GB
CPUs: 8
RHEL 5.8 64bit
Database size around 2TB
New server:
VMWare VM with Oracle 10gR2 10.2.0.5.8 on ASM
RAM 128GB
vCPUs: 16
RHEL 5.8 64bit
Copy of prod DB (from above server) - all init param are the same
I noticed that Index creation is slower on this server. I ran following query:
SELECT name c1, cnt c2, DECODE (total, 0, 0, ROUND (cnt * 100 / total)) c3
FROM (SELECT name, VALUE cnt, (SUM (VALUE) OVER ()) total
FROM v$sysstat
WHERE name LIKE 'workarea exec%')
C1
C2
C3
workarea executions - optimal
100427285
100
workarea executions - onepass
2427
0
workarea executions - multipass
0
0
Following bitmap index takes around 40mins in prod server while it takes around 2Hrs on the VM.
CREATE BITMAP INDEX MY_IDX ON
MY_HIST(PROD_YN) TABLESPACE TS_IDX PCTFREE 10
STORAGE(INITIAL 12582912 NEXT 12582912 PCTINCREASE 0 ) NOLOGGING
This index is created during a batch-process and the dev team is complaining of slowness of the batch on new server. I have found this one statement responsible for some of the grief. There may be more and I am investigating.
I know that adding "parallel" option may speedup but I want find out why is it slow on the new server.
I tried creating a simple index on a large table and it took 2min in prod and 3.5min on this VM. So I guess index creation is slower on this VM in general. DMLs (select/insert/delete/update) seem to work with better elapsed time.
Any clues what might be causing this slowness in index creation?
Best regards

I have been told that the SAN in use by the VM has capacity of 10K IOPS. Not sure of this info helps. I don't know more than this about the storage.
What else do I need to find out? Please let me know - I'll check with my Sys Admin and update the thread.
Best regards

Why is Thunderbird running very slow on Windows 7 CAUSE: McAfee

Installed Thunderbird ver 31.6.0 on my desktop Windows 7 Home Premium, SP1, 32bit, 4G ram, Intel i5 2.66 GHz,
a few months ago and it ran great at first.
Now that I've used it awhile it has slowed down considerably.
All functions of Thunderbird are slow, clicking to highlight a group of messages, deleting even just a single message, opening a message, etc.
It has compacted the folders several times, and I do not have a large number of stored messages (maybe total of all folders including trash, spam, sent, etc is around 500).
I am running McAfee Anit-Virus which does scan email attachments.
Has there been reports of slow performance with Thunderbird on Win7?
Perhaps my problem is caused by McAfee?
Thoughts, suggestions are welcomed,
Thank you,
Ken

Why Portal will be slow when we work on Theme Editor

Hi Experts,
Why Portal will be slow when we work on Theme Editor in Creating new Theme or modifying existing one.
Note: Since i have done Branding for 6 to 7 Clients i fell same , portal runs very slow.
Thanks
Vijai

Hi,
use the Eclipse Theme Editor. No need to be logged on in the portal, hence: faster. You'll only have to upload the theme afterwards to the portal.

Why does Firefox performance slow down after starting Jack server?

Hello,
I started configuring my audio on my system. So, I want to have jack working (not jack2, to work with wineasio) with best sound quality with all sound routed through jack. When i start jack server with this command and settings:
killall jackd;killall pulseaudio;jackd -R -t 1000 -d alsa -P hw:0,0 -r 48000 -n2 -D
Firefox slows down, opens new pages slow and the scroll down is very very slow. I had this issue with other distros too. I suspect that it has to do with realtime ( which i need for my audio related apps like traktor through wine, ardour, ableton through wine etc) without being sure about it. Any idea why this is happening?

zabrielza wrote:I had this issue with other distros too.
This smells like hardware problem. Do this:
1. Kill pulseaudio, jack, and make sure they are killed
2. Make sure you do not renice anything or apply other such tweaks
3. Run jackd -d alsa
4. Use your system
5. If unsatisfactory, try jackd -d alsa -p 1024 -n 3
6. Use your system
Jack runs with realtime priority by default (no flag required), and we still use the audio group to provide that privilege. I also do not advocate the realtime kernel, but you may try it. Jack not functioning well (i.e. hampering other tasks significantly) on a standard kernel is cause for concern.
You can read/grep your dmesg and systemd journal for suspicious messages. You may try running real-time audio tasks in another operating system with your hardware, and upon success may proceed to debug the problem on Linux, possibly with the help of the alsa developers.
Or better yet, grab a supported semi-pro external audio device if jack is important for you. However, this may not help if the problem is somewhere deeper, e.g. at the hardware interrupt level.

Motion 5 - I have 12gb of ram so why are you so slow?

Been using motion 4 a ton at the office and it has been slowing down my computer to a crawl and I am not sure why:
1. I have a pretty new mac with 12gb of RAM
2. Even though I constantly need to jump into Bridge and Photoshop, I bite the bullet and shut them down to appease the computer gods. Still no luck.
Here are my other stats:
OS X: Version 10.8.2
Proc: 3.4 GHz i7
Mem: 12 GB 1333 MHz DDR3
Yeah, so should I be looking into nuclear power supply to get this program running correctly or ***?

It could be your second display.
I did a test and added 5 particles playing at the same time. With three displays on and with only the iMac display on. No slow down... I put another 5 particles.... Slow down but not much.
I distributed all 10 particles throughout the timeline, no slow down with one display or three displays.
You have to remember when you add more (for example particles). You will always have a slowdown. Motion is like Flash. Motion has to display objects on the screen at retime, on the fly. For a particles it has to compute the object on the fly. (Flash has to do this inside a browser.)
One last thing... make sure you have fixed resolution turn on for each layer group. This will make sure That each image... video... object and particle doesn't display beyond the bounding video box within Motion. If not set Motion still has to computer for these objects beyond the video bounding box.

Hi Sushant,
It is possible to see the 3 DSO tables data in through SE16. May be you do not have authorization to see data through SE16.

HT1918 why do i have to create a new itunes account because I moved to Canada from the U.S.?

why do i have to create a new itunes account because I moved to Canada from the U.S.?( My current account won't let me change my address to canada so my billing address for account is incorrect, making it impossible for me to buy anything). Will it affect what I am able to put on my device i.e. already downloaded apps, music, etc?

VI running very slow in a new PC

Hello,
I recently changed my development PC, and one of my VIs is running much slower in my new PC. This is strange since the new PC is a bit better. In this PC I have an Intel i5 4210M 2.5GHz CPU, 8Gb of RAM and a disk with 7200RPM and 16MB of cache. The PC I was using before had an older intel i5 3210M CPU, 4GB of RAM and a 5400RPM disk.
In the current project I'm working I'm monitoring some production lines. I'm using Labview 2013 and the DSC module's OPC server to connect to the PLCs on the production line.
In the VI that is slower in the new PC I'm reading about 50 shared variables from the OPC server, I'm registering some data in a MySQL database, datalogging data on the Citadel database and registering alarms. On my older PC each iteration on this VI was taking about 1 second and now is taking more than 10 seconds.
I've noticed that when I run that VI the disk usage gets very high (constantly over 90%), but it's strange if the disk is causing this problem since it is better than the one I had on the older PC. The CPU usage is low (arround 5%) and the memory usage stays arround 30-35%.
Does anyone have any idea what could be happening? I'm getting very frustrated with this problem since the PC is brand new and I wasn't expecting to have a problem like this.

With windows 7 I was having the same problem. I installed windows 8.1 because since I was having some problems with drivers compatibility on windows 7 and I tought that maybe this problem in the execution speed could also be caused by that. But on windows 8.1 there was only a slight improvement - it took close to 20 seconds to execute now it takes 15 seconds, but still not the performance I was having on the previous PC (arround 1 second).
Today I brought both PCs and I'm trying to understand what's different. I've noticed on the windows resource monitor that the write speed on my new PC's disk are lot slower when the VI is running. The disk load goes up to 100% but the write speed seems to be limited to 1MB/s. As for the older PC the disk load stays lower (arround 30-40%) and the write speeds goes up to 5MB/s. I've also ran perfmon but I didn't noticed major differences between when I was running that VI and when I wasn't. I've attached some screenshots from the resource monitor of both PCs. The screenshot that is in portuguese is from the older PC but the fields are in the same positions as in the english version.
So I'm thinking that this must be some problem on my disk confgurations something must be limiting my disk speed to 1MB/s. But when I transfer files on the PC it doesn't seem to have that problem. I only noticed it on that VI...

Why can't I connect to a new wifi?

Why can't I connect to a new wifi? When I click on the wifi account it takes me to the IP Address page not the password page.

Contact Rhapsody to see if they have or plan to release an update for the app. Try uninstalling and reinstalling the app. Have you tried resetting your device by pressing and holding the Home button and power button until the silver apple appears?

Why, Oh Why can't Verizon get me the new Pre???!!!!

Why is it, that all the nice new smart phones end up getting a sweet deal to an exclusive network? Verizon is the best and most reliable network in my geographical location, and I can't get the phone I want!!!
I'm not degrading AT&T at all, I just want the new Pre, and just like NOT being able to try an I-Phone, I can't try the Pre!
I was a die-hard Palm Treo user for 5 yrs, until I finally heard that there wasn't going to be anymore Palm phones introduced, and two months later.....BAM, the new Pre gets introduced! So, here I am, stuck using a windows mobile 6.1 piece of junk, and I'm frustrated! What's a guy to do?
Sorry for my rant. lol
