Upload to solaris slower than to wintel
I posted a similar question before but have not resolved the issue so...
I setup WLS 6.1 on a wintel, 500MHz laptop
and WLS6.1 on a E220R running Solaris 8
my client browser is IE 5.5 running on Win2k
I tested the time it takes to upload a file using the console to upload an
EAR file
when I upload a 2.5Mb EAR to wintel it takes about 5 seconds to upload and
install
on the solrais box it takes about 35 seconds, most of this time is spend
uploading the file
why is it so much slower to upload to solaris?

Jim,
Experienced similar performance deltas when compiling JSP pages from the
command line. On wintel it takes about 10 minutes for several hundred pages
whereas it takes at least several hours on Solaris using exactly the same
script to compile. I cannot give you the precise time difference since I
killed it after two hours on Solaris. Recieved the old shoulder shrug when
the subject was brought to the attention of WL support. No answer.

Why is the download/upload speed so slow on my MBA (about 5 times slower than my PC)?

Are you on band 13 or band 4? 13 is the original LTE band and remains relatively congested. Band 4 is the XLTE band and is less congested and has higher overall potential bandwidth (15 MHz vs 10 MHz). Even so, 7 Mbps is more than enough for doing stuff on your phone and is not considered slow.
To check band,
dial *3001#12345#*
select serving cell info
frequency band will say 13 or 4
FInd an area with band 4 and retest. -

I using FF-5-Stable. It much slower than Google Chrome 13. & crash during upload ??
it takes too much time to open a page.
Always Crash during upload..for big or small file..
It hangs and closed through Task manager or Reboot...1. What are you "uploading"?
2. Have you tried a new Profile? Profiles don't last forever, and after going through a few major version updates "things" slow down, depending upon how much stuff the user has added to Firefox. Personally, I have created a new Profile for every new version of Firefox I have installed, up through Firefox 4.0. Didn't do that for Firefox 5, and probably won't for Firefox 6, due to the new fast release schedule and the fact that Firefox isn't being changed as much from one version to the next as it used to be changed under the 10 to 14 month intervals between major versions.<br />

Sun JDK 1.3 slower on Solaris 8 than Linux 6.2
I'm doing platform testing to determine which OS will run my application the fastest. I
have a RH Linux 6.2 box with dual p3-700's /512 Mb RAM running WLS 5.1 sp 5 with
Sun's JDK 1.3 and a Sun E-250 running Solaris 8, with dual Sparc 400's / 512 Mb
RAM running WLS 5.1 sp5 with Sun's JDK 1.3 Amazingly, the Linux box runs about
2x to 3x faster under load than the Sun box. Based on the hardware being used, one
would assume the Sun box would be AT LEAST as fast if not FASTER than the Linux
box. Surely, Sun didn't write a JDK for Linux that outperforms Solaris. There are alot
of different features/switches to the 1.3 JDK, I tried using different combinations and
so far came to the conclusion that the JVM should be invoked with the following:
- server -XX:+UseThreadPriorities -Xms256m -Xmx384mIf you are just looking for raw performance, you will do better on x86.
Even at the same mhz, you will typically get better performance from an x86
processor (e.g. P3). If you are looking to save money up front, obviously
you can't beat commodity x86 hardware running Linux. There are those who
believe that you save a lot of money (and headache) over the long term by
going with Sun Sparc running Solaris.

Well the question I was asking was what kind of analysis to do.
I'm not sure what else to tweak, configure, or manipulate. The
app doesn't hit a db in testing, rather we have it reading from a
rowset locally on disk to eliminate any latency associated with db access.It is highly CPU bound, the piece of the app in question processes data
through some complex algorithms to provide data back to the web server. Do
you think the SPARC 400's are really 2x slower than the P3-700's? If that's
the case, then
it would be a hard sell to run a java app on a Sun box at 5x the cost ofrunning it on Linux.

You'd have to do some more analysis to figure out why the Linux box is

What is your application doing under load? Are you hitting a database?
Are you cpu-bound, io-bound etc?
FWIW, if you were cpu-bound, a p3-700 is quite a bit faster than a
Sparc-400. However, web applications are rarely cpu-bound.

Home Hub 3 is slower than dial up.
I used to be on a voyager 220v router but started having connection problems. After speaking to customer support, and after they ran some tests on the line/router, they told me that the fault was with the 220v and as it was obsolete, i would need to change to a HH3.
After receiving the HH3, im now finding that the d/l speed for webpages is slower than it was on dial-up. Ive tried running speedtester but it fails to complete and just gives an error that it cant be completed at this time and to try later. After reading another thread on this issue, i went and found the settings from the hub itself, these are posted below:-

is their anything amongst the above which explains why its running so slowly?Bah, this is a PITA.
Got up around 7am and the HH3 was displaying connection time of 10 hours, great, lets leave it for 24 and see what happens. Tried browsing and pages were incredibly slow to load, thats when they did actually load. I said stuff it and took the dog for a walk and left everything as is. Got back and checked again at 9.15 to find a connection time of 14 mins, so obvioulsy something has reset itself.
Tried speedtester and quite simply, the page would not load in order for me to test it.
Tried clean line check, sounds perfect, no noise whatsoever on it.
Tried connecting to the test socket and now get the following results:-

Mac OS internet 5x slower than Windows 7 on BootCamp
Alright, here is my problem...
My one and only computer is a mid 2010 iMac... I recently moved to a new place. Prior to me moving I was stuck with an awful 3Mbps download speed. (You can tell how much I hated it by looking at my username) Now that I moved, I am able to get much faster internet. So, I got a plan that offers up to 50Mbps download speeds (Xfinity Blast cable internet). I didn't want to rent my ISP's modem/router, so I purchased my own. I got a Motorola sbg6580. As soon as I got everything hooked up, it seemed perfect. I used speedtest.net to see what I was getting. I first tested on Windows 7. To my surprise, I was getting around 70Mbps. I then restarted my iMac into the Mac OS to do some speed tests. On the Mac OS, I was getting around 50-60Mbps. A bit slower than Windows 7, but still very good. The next day I decided to do a "real world" test. I downloaded a 1 Gigabyte file just to see how fast it was. Now, if I was getting 50Mbps the file should have taken just under 3 minutes to download. Instead, it took around 7 minutes. I figured it was maybe just the website I was downloading from. (the file I was downloading was the Cry Enginge SDK - http://www.crydev.net/ ) I did some research and discovered the website testmy.net - I am not sure if this is completely reliable or not, but every test I do on testmy.net I get around 10Mbps. At first I thought it was my ISP ripping me off, then I decided to do a testmy.net test on Windows 7 via BootCamp. (please note that on both Mac OSX and Windows 7 I did multiple tests over the coarse of multiple days) On Windows, I could instantly tell that the test was going much faster. The results for testmy.net on Windows 7 were 50-60Mbps. I did not completely trust the website, so I downloaded the same Cryengine SDK on Windows. It took around 3 minutes, just as it should have. I researched a bunch online trying to find info on this problem. I tried many "solutions" but none of them changed anything. (these include but are not limited to: Tried different DNS servers, Disabled ipv6, disabled sbg6580 firewall, disabled mac osx firewall, tried changing the wireless channel, and reset sbg6580. I came to the conclusion that it was the sbg6580. I thought that maybe an airport express would give me better results. So, today I bought an Airport express. With the sbg6580, I was able to disable the router features so it was just a modem. I was then able to set up the Airport express as my router. It fixed nothing. I am still getting the same results, Windows is still getting anywhere from 50-60Mbps while Mac OSX is getting around 10Mbps. I am out of ideas, if anyone could please help me that would be great. Also, if you need to know anything else please let me know. I may have missed something...
A quick note:
At my old house I had my iMac hooked up to a surge protector. For maximum internet performance, my iMac was connected to my router with an ethernet cable. During a bad storm one day, a lightning bolt either hit my house or very close to it. Ever since, my ethernet port has not worked. I have tried multiple eithernet cables as well as multiple routers and networks. I do not have the money for apple to completely replace my logic board. - So anyway, I am unable to test the performace with an eithernet cable.
Extra information:
My sbg6580 as well as my Airport extreme are both sitting on the same desk as my iMac, so it is obviously not a signal problem.
I also own both a iPod touch 5th gen and a iPad 2nd gen. I am getting around 20-30Mbps on both of them. I am not sure what would be a "good speed" on either of these, but I figured that was pretty good for a tablet and ipod.
The upload speeds on both windows 7 and Mac OSX are around the same 5-10Mbps.
I am using Google Chrome on both Windows 7 and Mac OSX but, I have also tried Firefox and Safari.Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test. -
A Forum That is Slower Than Jive!
I wouldn't have thought it possible, but I found a forum that is slower than Jive!
I'm tired of "not my kind of book" letters from literary agents, so am going to go Amazon/Kindle as soon as I finish the 2nd book of a 2 book set
When reading about Kindle publishing at http://forums.kindledirectpublishing.com/kdpforums/forumindex.jspa I discovered a REALLY slow to load forum
Oh well... hopefully the process will be simple, once I'm ready, and I won't have to ask many questions in that forum>good luck with getting it published
Grin... will not be a problem AT ALL with Amazon/Kindle, since it is free to upload... and then it is just a matter of seeing how many people look for a book in your chosen genre, and buy what you offer after reading the synopsis (actually, one message on the Kindle user-to-user forum said the 1st 10% of the book is put in a preview section for people to read for free to make a decision)
When my 2nd book is finished in a few months, I'll see how many people want to read a murder mystery with paranormal elements -
Got fibre today, far slower than estimated
I upgraded from standard BT Broadband to Fibre, and my estimated speeds that were given to me were between 11-18Mbps for download and 0.8-1.3Mbps for upload. It was activated about 7 hours ago and I am getting the upload speed perfectly fine right now, though as you can see my current download speed is about 3Mbps. I was wondering if I had to wait a while/few days for the speed to increase to the estimates? The speed I have now is really no better than my standard ADSL was.
EDIT: I should point out that my line was recently fixed by an engineer as there was a problem with the landline ringing incorrectly and my old broadband was being even slower than usual.

System Stats on Sun Solaris poor than on Windows
Hi,
I have freshly gathered system stats on my Windows 64bit DB and Sun Solaris T3 SPARC but for some reason the stats on Windows look superior to those on Windows.

Preview takes forever to open, much slower than on my old MacBook running Snow Leopard. It has been like this since I bought the computer last January. Any ideas?
Take it to an Apple Store for testing. If you don't get immediate satisfaction, exchange it for another one, which you can do at no cost, no questions asked, within 14 days of delivery.

Why is Thunderbolt so much slower than USB3?
I'm considering two different drives for Time Machine purposes. Both are LaCie. Either of these:
- Two Porsche 9233 drives, 4 TB each
OR
- A 2Big Thunderbolt drive, 8 TB, which I would configure as RAID 1 (a mirrored 4 TB volume)
My question is this: I've viewed both of these product pages via the Apple Store, and I noticed that LaCie's information for the Thunderbolt drive makes it a lot slower than the USB drives. Meaning: They say that the 2Big Thunderbolt drive maxes out at like 427 MB/s, whereas the Porsche USB drives max out at 5 GB/s. Why is this? Isn't Thunderbolt supposed to be a lot faster than USB (any iteration)?Not an easy question, short of a whole lot more detail on the construction of those two devices. You're likely going to need to look at the details of the drives and probably at some actual data. You're really looking for some real benchmark data that you can compare, in other words. Particularly which (likely Seagate) drives are used in those (IIRC, Seagate bought LaCie a while back), and what the specs are.
The hard disk drives themselves are a central factor, where the drive transfer rate is a key metric for big transfers (and that can be based on drive RPM as much as anything, faster drives can stream more data, but they tend to need more power and run hotter), and access (seek) time for lots of smaller transfers (faster seeks mean faster access, so good for lots of small files scattered around). Finding the details of the drives can be interesting, though. I've seen lots of cheaper disks that spin very slowly, which means that they can have nice-looking transfer times out of any cache, but then... you... wait... for... the... disk... to... spin.
The device bus interfaces can also vary (wildly) in quality. I've seen some decent ones, and I've seen some USB adapters that were absolute garbage. Some devices have decent quantities of cache, too. Others have dinky caches, and end up doing synchronous transfers to hard disks, and that's glacial compared with memory speeds.
One of your example configurations also features RAID 1 mirroring, which means that each write is hitting both disks. The writes have to pass through a controller that can do RAID 0 mirroring, and that can write the I/O requests to both drives, and that can read the data back from (if it's clever) whichever of the two drives is best positioned in related to the sectors you're after. If it's dumb, it won't account for the head positions and drive rotation and sector target. Hopefully the controller is smart enough to correctly deal with a disk failure; I've met a few RAID controllers that weren't as effective when disks had failed and the array was running in a degrated mode. In short, RAID 1 mirroring is a reliability-targeted configuration and not a performance configuration. It'll be slower. Lose a disk in RAID 1 mirroring, and you have a second disk with a second copy. If the controller works right.
If you want I/O performance without reliability, then configure for RAID 0 striping. With that configuration, you're reading data from both disks. But lose a disk in a RAID 0 striping configuration and you're dealing with data recovery, at best. If the failure is catastrophic, you've lost half your data.
But nobody's going to make this choice for you, and I'd be skeptical of any specs outside of actual benchmarks, and preferably benchmarks approximating your use. Reliability is another factor, and that's largely down to reputation in the market; how well the vendor supports the devices, should something go wrong. One of the few ways to sort-of compare that beyond the reviews is the relative length of the warranty, and what the warranty covers; vendors generally try to design and build their devices to last at least the length of the warranty.
Yeah. Lots of factors to consider. No good answers, either. Given it's a backup disk, I'd personally tend to favor eliability and warranty and less about brute speed.
Full disclosure: no experience with either of these two devices. I am working with Promise Pegasus Thunderbolt disk arrays configured RAID 6 on various Mac Mini configurations, and those support four parallel HD DTV video streams with no effort. The Pegasus boxes are plenty fast. They're also much more expensive than what you're looking at. -
URLClassLoader slower than system loader
I'm subclassing URLClassLoader to load jar files on the local file system. I noticed that URLClassLoader loads about 30% slower than placing the jar files on the system class path. In my app, class loading performance in very important -even though it is just a one time hit.
I suspect the URLClassLoader (which I believe is implemented mostly in Java on Sun's VM) is not leveraging the many performance optimziations that the system loader enjoys (which is probably implemented in native code).
I also experience the same performance issue if I try to do jar loading myself using Java ZipFile i/o.
Comments?well there is quite more overhead involved - loading from classpath of course is the most optimized one.

I have my Mac Book Pro with the OS Yesomite since a month and I am feeling that my mac is getting slower than before a month. I want to install OS Lion on my mac. I think i have a DVD of OS Lion which comes when i bougnt Mac laptop in 2011. Should i install OS Lion? What wil happen if i install OS Lion, do i lost my Applications or ...????
Hi, the last install dvd that came out for mac's was Snow Leopard,10.6.3. Lion is a download from apple. You cannot just install it over Yosemite. You would have to backup your drive to save files you want and do a clean install. You might want to look into getting more memory. You can run 8 Gig"s of memory on your Macbook Pro.If your Macbook Pro is getting really slow you might want to download EtreCheck and then post the results here.http://www.etresoft.com/etrecheck Check out this article. http://support.apple.com/kb/PH19031

Flash player 10.1 slower than 10
At least, that's how it is on my secondary computers. On my Dell Inspiron B120, flash 10.1 latest is like a train wreck when it comes to playing Youtube videos in full screen. Disabling hardware acceleration helped a little, but this shouldn't be happening as I uninstalled 10.1 and installed an archived version of Flash 10 with much better playback AND with h/w acceleration enabled. The laptop uses XP SP3 and Firefox.
Simply put, Flash 10.1 feels a lot slower than 10 on my Dell laptop (1.4 GHz celeron-M, intel 915g video, 512 mb ram)
And there's another odd but minor problem I seem to be having with is flash animations on my main computer and any other computer/laptop I have using Flash 10.1. I get this alternating 'lag' every few seconds; it's like the computer is dropping frames because the CPU can't keep up. I could completely understand this, but this is happening on practically any flash animation I throw at the computer. I just tested a flash movie (SWF format) on my main computer (2.8 GHz AMD Athlon x2 240; 2 gb ram, Windows 7 x64, Firefox) and I get this irritating choppy lag here and there. Again, with the previous Flash version 10, I did NOT have this problem AT ALL. Everything was silky smooth; the only benefit I'm getting from Flash 10.1 is x264 hardware acceleration for my ATI Radeon 4200 HD. Before anyone asks, all of my computers were using the latest flash version AND video drivers prior to these tests.
I am VERY frustrated with these problems as I've posted a similar thread twice now in the past. No one seems to be answering or helping me with this; Those that do reply simply claim that they're having the same problem.
Adobe, please look into this problem. Eventually Youtube and several other sites will force me to upgrade my laptop to Flash 10.1.Has Adobe fixed the problems with version 10,1,82,76 of flash player ?
I compared it and found nothing but problems.
I then uninstalled 10,1,82,76 and rolled back to 10,0,12,36 which works fine on Firefox and Opera but I can't install 10,0,12,36 on Exploer or Chrome
it keeps telling me there is a new version even when I try to install it from local drive with a archived version.
With all the complaints about 10,1,82,76 and the lack of response from Adobe on any fixes I will not be using Adobe auto updates until I let some
other poor guinea pigs suffer all the bugs and problems first.
You would expect a large company to have better development and testing before imposing buggy upgardes on us.
