Performance issue on LOV in JSP

Hi,
In my JSP application, I used two LOV for look up. One of them will show about 3,000 and so records. When I clicked the LOV button for this LOV, it took me more than 20 seconds to see the result. This is unacceptable. Is there anyone know how I can tune the BC4J framework to improve performance? Your any input will be highly appreciated.

On many projects I've worked on, including non-JDev, a general user interface rule was that you don't use an LOV if there's much more than 20-30 items. Think of this from a USER standpoint.
Note also that in Swing/DACF the combobox does NOT allow you to type the letters "starting" and automatically jump to the right place.. ( i.e. Enter WI in a state list doesn't take you to WISCONSIN ). This is a Sun JDK issue. ( Or has it changed in 1.3 in some manner... or is there a property set to allow this? )
As such, you've more a application design issue than a performance issue.
Good Luck

Performance issues with LOV bindings in 3-tier BC4J architecture

We are running BC4J and JClient (Jdeveloper 9.0.3.4/9iAS 9.0.2) in a 3-tier architecture, and have problems with the performance.
One of our problems are comboboxes with LOV bindings. The view objects that provides data for the LOV bindings contains simple queries from tables with only 4-10 rows, and there are no view links or entity objects to these views.
To create the LOV binding and to set the model for the combobox takes about 1 second for each combobox.
We have tried most of tips in http://otn.oracle.com/products/jdev/tips/muench/jclientperf/index.html, but they do not seem to help on our problem.
The performance is OK (if not great) when the same code is running as 2-tier.
Does anyone have any good suggestions?

I can recommend that you look at the following two bugs in Metalink: Bug 2640945 and Bug 3621502
They are related to the disabling of the TCP socket-level acknowledgement which slows down remote communications for EJB components using ORMI (the protocol used by Oracle OC4J) to communicate between remote EJB client and server.
A BC4J Application Module deployed as an EJB suffers this same network latency penalty due to the TCP acknowledgement.
A customer sent me information (that you'll see there as a part of Bug# 3621502) like this on a related issue:
We found our application runs very slow in 3-Tier mode (JClient, BC4J deployed
as EJB Session Bean on 9iAS server 9.0.2 enterprise edition). We spent a lot
of time to tune up our codes but that helped very little. Eventually, we found
the problem seemed to happen on TCP level. There is a 200ms delay in TCP
level. After we read some documents about Nagle Algorithm, we disabled a
registry key (TcpDelAckTicks) in windows2000 on both client and server. This
makes our program a lot faster.
Anyway, we think we should provide our clients a better solution other than
changing windows registry for them, for example, there may be a way to disable
that Nagle's algorithm through java.net.Socket.setTcpNoDelay(true), in BC4J,
or anywhere in our codes. We have not figured out yet.
Bug 2640945 was fixed in Oracle Application Server 10g (v9.0.4) and it now disables this TCP Acknowledgement on the server side in that release. In the BugDB, I see backport patches available for earlier 9.0.3 and 9.0.2 releases of IAS as well.
Bug 3621502 is requesting that that same disabling also be performed on the client side by the ORMI code. I have received a test patch from development to try out, but haven't had the chance yet.
The customer's workaround in the interim was to disable this TCP Acknowledgement at the OS level by modifying a Windows registry setting as noted above.
See Also http://support.microsoft.com/default.aspx?kbid=328890
"New registry entry for controlling the TCP Acknowledgment (ACK) behavior in Windows XP and in Windows Server 2003" which documents that the registry entry to change disable this acknowledgement has a different name in Windows XP and Windows 2003.
Hope this info helps. It would be useful to hear back from you on whether this helps your performance issue.

PERFORMANCE ISSUE IN LOV(ORACLE FORMS)

I have a requirement to populate an LOV in a Form Which is taking LOT of TIME (PERFORMANCE ISSUE)
the Record Group Query is as
select segment1 INVENTORY_ITEM ,
inventory_item_id,
description,
primary_uom_code,
decode(service_item_flag, 'Y', service_duration, NULL) service_duration,
service_duration_period_code,
shippable_item_flag,
Decode(bom_item_type ,
1,'MDL',2,'OPT',3,'PLN',4,
Decode( service_item_flag,'Y','SRV',
Decode( serviceable_product_flag,'Y','SVA','STD'))) item_type_code
from mtl_system_items_b --table name
where organization_id = :QOTLNDET_LINES.ORGANIZATION_ID
AND (bom_item_type = 1 or bom_item_type = 4)
AND vendor_warranty_flag = 'N'
AND primary_uom_code <> 'ENR'
AND ((:QOTLNDET_LINES.LINE_CATEGORY_CODE = 'ORDER' and customer_order_enabled_flag = 'Y') OR
(:LINE_CATEGORY_CODE = 'RETURN' and NVL(returnable_flag, 'Y') = 'Y'))
AND segment1 like :QOTLNDET_LINES.INVENTORY_ITEM || '%'
When ever i give :QOTLNDET_LINES.INVENTORY_ITEM from Front end This LOV need to be displayed.
IT IS TAKING MORE THAT 3 MINUTES DEPENDING ON THE ITEM GIVEN.
SUGGEST ME TO REDUCE THIS TIME.
Thanks,

If i can give Full item name then dynamically I will assign Record_group1 else i will assign Record_group2 by using Set_LOV_Property()
so that if i give full item name lov is populated quickly .
Suggest me Which Triggers Should i use.

Jsp performance issue on Safari

Hi,
We are facing performance issues while loading a jsp page in Safari browser on Macintosh.It takes around 2 minutes to load.
The same page used to take around 5 seconds on Netscape on Macintosh.
Have anyone faced a similar issue?
I'm new to jsp, so could you please provide some tips on how we can debug what is causing the issue and tune this?
Thanks,
Mini

Performance Issue in Order.jsp

Hi Folks,
I am facing a performance issue in the CRM system. When I try to transfer 500 items from the Product catalog to the order, it takes around 8 mins.
The expectation is max of 1 min.
We are performing the ATP check via ECC and pricing via IPC. I would like to have your suggestions as to how I could improve this performance.
Thanks.
Deepika

Frankly, you may never be able to achieve that kind of benchmark.
But it is still worthwhile to trace for performance. Check the time taken by the (ABAP calls) components in the "Add to basket" action. The ISA runtime log will be very useful. Perform ABAP trace in the backend ST03, ST05 etc.
If you have not seen this note check if this is relevant.
Note 1089043 - Performance and memory problems in SAP E-Commerce
See if this note is relevant too
Note 1150302 - Deactivating IPC communication in Web catalog of Web shop
A different question,
What is this business scenario that expects a customer to select 500 catalog items in one shot and transfer to the basket. To me, it looks very highly unlikely scenario - unless you want to explain
If this is a kind of customerr specific view and you expect the customers to select all of the items in their view and load in one shot, you can design upload capability with ofline order create.

Returning multiple values from a called tabular form(performance issue)

I hope someone can help with this.
I have a form that calls another form to display a multiple column tabular list of values(needs to allow for user sorting so could not use a LOV).
The user selects one or more records from the list by using check boxes. In order to detect the records selected I loop through the block looking for boxes checked off and return those records to the calling form via a PL/SQL table.
The form displaying the tabular list loads quickly(about 5000 records in the base table). However when I select one or more values from the table and return back to the calling form, it takes a while(about 3-4 minutes) to return to the called form with the selected values.
I guess it is going through the block(all 5000 records) looking for boxes checked off and that is what is causing the noticeable pause.
Is this normal given the data volumes I have or are there any other perhaps better techniques or tricks I could use to improve performance. I am using Forms6i.
Sorry for being so long-winded and thanks in advance for any help.

Try writing to your PL/SQL table when the user selects (or remove when deselect) by usuing a when-checkbox-changed trigger. This will eliminate the need for you top loop through a block with 5000 records and should improve your performance.
I am not aware of any performance issues with PL/SQL tables in forms, but if you still have slow performance try using a shared record-group instead. I have used these in the past for exactly the same thing and had no performance problems.
Hope this helps,

Multi Select Choice on af:query has severe performance issue

Multi-select choice used with af:query through a view criteria is causing severe performance issue on deselection of "All" checkbox, if the data in the list is around 550 rows. The same component works absolutely fine when used in a form layout.
I can provide you a re-producible test case, if anyone needs it!
***: This is a customer environment issue, and customer is eager to have multi-select in this case. Appreciate any help!

Performance issue with Jdeveloper

Hi Guys,
I am experiencing strange performance issue with Jdeveloper 10.1.3.3.0.4157. There are many other threads regarding the performance issue in this forum, but the problem I have is a little bit different.
I have two computers: one is Athlon 3200+ with Vista and another one is P4 dual core 6400 with XP (service pack 2). Both of them have 2GB memory.
I am running the same simple project on both computer, but only the one with Vista has the problem. The problem is very similar to the problem mentioned in the thread:
Re: IDE has become extremely slow?
But it's much worse. It only happens only on JSF pages. Basically, any operations on the JSF pages are very slow. Loading the page, changing the attributes of a button in source editor, or even clicking the items in the design view take forever to run.
The first weird thing is that it may use 100% CPU, but it never recover, which means the 100% CPU usage never stops or when it stops, the Jdeveloper stops responding.
The second weird thing is that the project is not big. Actually, it's very small. The problem started to happen since last week. There are not big changes during the period. The only thing I can say is that we created two more JSF pages.
The third weird thing is that the same project never happened on the P4+XP box. When I open the project on the P4+XP box, it’s always fast and no CPU spike.
Any advises are welcome!
Thanks,
Steven

Hi Guys,
I re-made a simple test project for this problem and now I now always reproduce the problem in JDeveloper on both system (XP & Vista). Everytime I open this jspx file in the source editor and try to scroll up/down the source file, or manually delete an attribute, JDeveloepr will hang and the CPU usage is 0%.

After Effects CS5.5 - Very Serious Performance Issues w/RAM Preview

My system: Windows 7 Professional, two Intel Xeon X5650's, 12GB RAM, and a NVIDIA Quadro FX 4800.
Problem: RAM Preview in CS5.5 gives me less than 2 fps (yes---two frames per second). This is even with the most simple of compositions. I created a 1080p 23.976 project with two simple solid layers and keyframed position and scale values for one of them with no other effects on either solid. RAM Preview gives me 1.8 fps.
I still have AE CS5 installed and it gives me solid, predictable results with RAM Preview. When I create a similar test project inside CS5, it creates the RAM preview almost instantly and displays in proper realtime (23.976 fps).
My settings for both CS5 and CS5.5 are similar (and I have tried many variations in my attempt to fix this problem).
PREVIEWS
Fast Previews: Adaptive Resolution Limit 1/4
Enabled OpenGL and both sub-options for OpenGL enabled.
MEMORY & MULTIPROCESSING
RAM reserved for other apps: 4GB
I have tried various settings for Multiprocessing, all of which results in the same less-than-2 fps RAM Previews. Currently I have MP'ing enabled with 1.5GB allocation per background CPU and the actual CPU's used is 4. Again, no matter what I set it to, I get the same performance issue.
On my screen magnification ratio setting, I am using 25% and my Resolution/Down Sample is set to quarter. On my preview tab, I have tried setting my resolution from the default of "Auto" to "Quarter" with no difference.
In summary: On the same machine, AE CS5.5 RAM Preview offers terrible performance; CS5 RAM Preview offers great performance.

Under AJA Preview there are check boxes, one for "Video" and the other for "Preview." I've checked and unchecked them both and I'm still getting poor RAM previews. No matter what I have toggled, I seem to get between 1 and 2 fps for my RAM Previews.
I am not currently using the AJA card for anything. I will consider uninstalling it if this might possibly solve my problem. It's just a hassle to install and uninstall cards on a per need basis.
If there are any other thoughts, I'd love to hear them. At this point, I'd do just about anything to have realtime previews back.
The machine I'm using, by the way, is an HP z800 with Windows 7 Professional, two Intel Xeon X5650's, 12GB RAM, and a NVIDIA Quadro FX 4800. It has the following installed: CS5.5 Production Premium, AVID Media Composer 5.5.2, and AVID DS 10.5.1 (among other programs).

CS3 Performance Issues - Productivity Crippled - S.O.S.

I was having performance issues and repeated crashes with AE CS3 on Win XP, so I talked my boss into upgrading me to CS5 and Win 7. All was well until we hired a new guy to help me with my video work load. He has inherited my old software and there's no money for another upgrade, so we're going to have to figure this out.
He running CS3 Master Collection on a Dell PC running Windows XP (Intel Core II Duo 2.33Ghz, 3.25GB RAM). The graphics card is the ATI Radeon HD 2400 Pro, which came stock with the machine. Specs on that card here: http://reviews.cnet.com/graphics-cards/ati-radeon-hd-2400/4507-8902_7-32763888.html?tag=sp ecs. Pretty wimpy, I know.
Anyway, my new coworker has been experiencing at least as much frustration as I was, with frequent crashes, a fickle RAM Preview and bad renders. His machine has more RAM and a faster processor than I had when I ran CS3, but his performance seems even worse Since CS3 won't handle AVCHD files, I've been converting our HD camera footage into 720p MPG 2 (Adobe Media Encoder) for projects he's assigned. I suppose that could have something to do with it, but I can't see why CS3 wouldn't run an MPG generated from CS5. Anyway, I asked him to write up a short list of the problems he's experiencing and he gave me this ...
- rendered movies are often corrupted with red frames that flash in spots
- when i try to render an MPEG2 at full res it will give me an error message that says:
After Effects: AEGP Plugin Media IO Plugin:
There is a mismatch between Output Module settings and Transcode Settings. Please verify your settings and try again.
Property Data Invalid!
MediaIO2 error: 0x400e0004
Frame dimensions out of bounds
(5027 :: 12)
- when i try to render a RAM preview, often it does not render the complete work area. it takes several attempts to preview the entire selection
- occasionally, when i bring in new media it gives a message saying 'media pending' and i will have to shut the program down and re-import the media
- it will often (1-3 times per hour) crash unexpectedly and give a message saying 'After Effects has crashed'
- when i try to render a RAM preview an error message pops up saying it needs at least 2 frames to render when i clearly have more than that selected
It's my hope that someone here will recognize a common thread between these various issues and be able to suggest a silver bullet that will fix it all. I realize that's not likely. Research to date has yielded glimpses of possible solutions involving cache and scratch discs, but there are few specifics and I'm not sure exactly what adjustments to make. I also have a spare Nvidia GForce 6800 graphics card form my own computer at home that I could donate to this office if it would help.
I'm about to pass these issues on to our Help Desk and let them deal with it, but I'd love to be able to at least point them in the right direction, since they mostly deal with standard office software and won't have much experience troubleshooting multimedia applications. I believe they also have the option to call Adobe for tech support over the phone, but I'd like them to have a clue if they do. Can anyone suggest what settings, drivers or hardware might be a good place to start to get my man's system running a little more smoothly? I'd really appreciate some insight before we start poking around blindly and I offer my thanks in advance for any forthcoming wisdom.
Thanks!
P.S. For what it's worth, my copy of CS5 is running like a champ on Windows 7 with the 64 bit OS. My machine has an ATI Radeon HD 2400 XT for a card, which can't be much better than the "Pro" version in my coworkwers machine, right?

No legal issues, both my CS5 and his CS3 are bought and paid for. However, if After Effects CS3 is incapable of rendering a decent looking file compressed to a reasonable file size, then I'm not sure how valuable it is to us anyway. It seems unbelievable to me that one of the most popular industry standard video aps isn't designed to render anything more than draft quality files for client review. Even if he renders an uncompressed file from AE, CS3 didn't ship with Adobe Media Encoder as a separate ap, so what can he do with it without resorting to third party software? I don't get it, but I'm clearly no expert on the subject.
So, things being what they are, what file format would you suggest I convert the AVCHD file to in order for my CS3 burdened coworkwer to be able to work with them? We are a Windows shop, so I don't know if Dave's Quicktime/PNG suggestion will work for us or not. You've always given good advice to me in the past, so if you have an alternate suggestion I'm eager to try it out. Just go easy on me with the jargon because I'm primarily a print designer and my video skills at this point are (obviously) intermediate at best!
In any case, I really appreciate both you and Dave taking the time to respond to my post. This forum continues to be the best resource I have for solving problems and augmenting my understanding of these programs. My thanks!

Photoshop CS4 performance issue

HI
we use App-V for almost all of our applications and we work with a local cache mode
as far as I know - the performance of a local application and the virtual application should be the same even if the package is big. a great example is Office 2010 App-V package which works the same as a local installation
We saw that there are some applications that run very slow comparing to a local installation on the same hardware
specifically - Adobe PhotoShop CS4 is a good example. when we load a 10MB picture and try to make a simple task like mark a selection - it takes forever for the application to response!
the weirdest think is that we tried to sequence the application both in App-V 4.6 SP3 and App-V 5.0 SP2 we got the same results. we tried the default things as reset the client's cache or allowing local interaction, com objects... etc.
I really have no idea what else we can do. as I wrote, larger applications work in our environment just fine, but there are some that stuck us. another application that works slower is NIS. I'm not sure if the performance issue is always from
the same reason but I'm trying to figure out what can we do to improve it
would love to get some ideas
Tamir Levy

Hello,
Since Microsoft made this claim (as stated by you), my recommendation to improve your situation still stands;
Open a ticket with Microsoft to understand the topic. My assumption would be that you could name the engineer who visited you a few years ago, and revisit the discussion you had with him and Microsoft directly.
(the statement of course goes against any independt benchmarking - such as
Project VRC,
acknowledged facts by the Community and more..)
As stated already; If you have tested all that you described, I can't offer anymore suggestions apart from the above.

LR 4.1 RC performance issues

I find that the 4.1 rc version is better than 4.0 but still not snappy like 3.6 was. Here are some things I have noticed that are slow:
• tagging images with flags, colors, labels, etc. - seems to be a two to three second delay when doing this before they register and show up with the files. I have write .xmp off.
• and in regards to writing to xmp off, if I select it, It seems to want to update my whole catalog (148,000 images) and if I try to quit, it promps me that it has not finished and do I want to quit and if I do it will resume upon restarting. At that point when I try to quit, it just hangs even if I tell it to quit writing xmp info. I let it go for a couple hours yesterday and it seems it still didn't finish and caused problems again trying to quit. I ended up having to force quit. I never remember this problem in the past and in the past, if you selected write to xmp or not, it used to do it or not do it from that point forward. Until this is fixed, I have it off and just manually save metadata using Cmd-S.
•When in library mode, moving between images is snappy, however once you go to the develop module, it slows to a snail's pace (3-5 second delay). I know develop module is not as fast in general for moving between images, but in ver. 3.6 there was only a slight delay (maybe 1 sec.). Now I'm bouncing back and forth wasting time switching modules, which brings me to my next performance issue:
* When switching from library to develop, it takes quite a few seconds to respond, then after that it loads the image with the loading... icon/message, and another few seconds are wasted. That used to be almost instantaneous in 3.6. Going to develop to library seems fine with only a slight delay.
• The adjustment brush is faster in 4.1 than 4.0 but not nearly as responsive as in 3.6 which is frustrating and very easy to overdo what you're trying to do by the time the brush catches up.
•Sliders still have a bit of jerkiness to them in develop module. Also sometimes when I grab a scrubby slider to move it, it highlights the field as if I want to enter a number. Wish this would not happen. If I want to enter the number, a single click should do it in the field. If I grab the scrubby slider, it should just activate the scrubby slider.
• Keyword suggestions take much longer to generate. In 3.6 as fast as I'd add keywords, the relevant suggestions would pop up right away.
• When zooming into 100%, it seems to be reasonably fast to render, but I've noticed sometimes it just shows the blurred semi-rendered version without actually rendering 1:1. Even unzooming and rezooming doesn't work. Only solution is to go to another image and then back to the original image and that seems to kick it into gear and re-initialize the rendering engine.
Overall I love the features and new process 2012, I'm just disappointed in the performance. Especially now that I'm trying to edit a large job. I really wish the program could be optimized to work as well as 3.6 did and I hope once the final version of 4.1 is released (hopefully soon) we will see an overall performance boost. I have removed ver 3.6 from my system so that's too much of a hassle to go back and not an option, plus I've gotten used to the new process and like it too much to go back.
From the posts I've read it seems others are experiencing this as well, as well as colleagues I've spoken to. It seems to be across platforms and regardless of computer specs (as long as someone's using a fairly updated and capable computer)
Thanks for working on a performance boost Adobe and getting ver. 4.1 dialed in and releasing a final version.

Cannot reproduce on Win7 64Bit (LR4.1RC).

Accounts Payable Rapid Mart Performance Issue

We are currently running the SAP AP Rapid Mart 3.2 and facing a performance issue on the SAP side for the data flows: DF_VendFinDocFactOpenDelta_SAP and DF_VendFinDocFactClearDelta_SAP. These data flows pull from the same tables and one of them being BSEG which is a rather large table.
Has anyone found a means to pull data for these two dataflows within a reasonable amount of time? I'm looking for a two hour or better abap run time for five years worth of data.

Hi Chuck,
I wish I could say that I have a solution. I ran nto the exact same problem a few months ago. Unfortunately we did not have enough time to come to a resolution of the issue, and then I moved on.
I would also love to hear anyone's suggestions regarding this issue.
BSEG is not a real table but a "virtual" table (like a view), so there are issues with how DI is able to pull data from BSEG.
Thanks

Lightroom 4 performance issues

Hello,
Months ago I switched from Aperture 3 to Lightroom 3 and quickly fell in love with the program.
I switched due to constant freezing and crashes in Aperture 3. I invested time and money to learn Lightroom 3. Performance in Lightroom 3 was superb. Anything I would do with regards to any type of adjustment gave instant results on the screen. Program never crashed or froze onec. Quite frankly, I was shocked in a very positive way.
This was on Macbook Pro i5, 8GB RAM, Hi Res Antiglare screen with Snow Leopard.
I purchased Lightroom 4. I did a clean install of OSX Lion and, clean install of LR4. New catalogs, no importing of anything. LR 4 is sooo slow. It works just like Aperture 3 worked, the precise reason that made me dump it.
The longer LR4 is opened, the slower it becomes. The more adjustments are applied, the slower it becomes. I will use brush and I have to wait to see results. I can't use brush. It takes me 15-30 min to brush small part of the image. I will slide adjustments and wait. I will click on crop tool and wait, wait, wait. I really love this program but I just can't work like that.
Would anyone share some light or advice on what could be done, on what is going on?
Thank you.

Rob,
I am working with NEF files and have done so in LR3. I understand from some reading that one of the benefits from converting files to DNG is that they are faster to work with. So I just copied one of my NEF as DNG and I have been working on it for about 15 minutes applying brush after brush and other adjustments to see if LR4 will slow down. Thus far it has been incredibly faster. I will continue to work on this one image and maybe convert few more to DNG to test but do you think that there might be some issue with NEF format? Another bizzare thing I just noticed is that when I open NEF image, my memory quickly goes up to over 3GB and that's not even during applying adjustments. Working now with DNG, memory is just around 1.3 GB. WHAT IS GOING ON HERE???
I wonder what type of files are other LR4 users that are reporing performance issues working with.
Please share your thoughts.
Thank you.

Performance issues in bw

Hi All,
What is buffering number?How it is useful in performance issue? Tell me the option where it is available? To set this what are navigational steps?
Thanks inadvance.

Hi Yogi,
A nice weblog by Vikas Please do check this.on number range buffering,

How to improve performance in reporting side?
Query Performance Techniques:
1. Check Query propertiesUse RSRT tcode
2. Check whether cube is compressed
3. Optimize query definition
4. Analyze query execution
5. Check for additional indexes
6. Archive unwanted data
7. Check for partitioning options
8. Check for additional aggregates ( Consider DB ratio and KPI ratio)
9. Check for parallelization options
10. Use Nav attributes instead of hierarchies, use free char and filters.
Possible causes for the performance :
A) High Database Runtime
B) High OLAP Runtime
C) High Frontend Runtime
Depending upon your analysis
A)Strategy - High Database Runtime
Check if an aggregate is suitable (use All data to get values "selected records to transferred records", a high number here would be an indicator for query performance improvement using an aggregate)
Check if database statistics are update to data for the Cube/Aggregate, use Tcode RSRV output (use database check for statistics and indexes)
Check if the read mode of the query is unfavourable - Recommended (H)
B)Strategy - High OLAP Runtime
Check if a high number of Cells transferred to the OLAP (use "All data" to get value "No. of Cells")
a) Use RSRT technical Information to check if any extra OLAP-processing is necessary (Stock Query, Exception Aggregation, Calc. before Aggregation, Virtual Char. Key Figures, Attributes in Calculated Key Figs, Time-dependent Currency Translation) together with a high number of records transferred.
b) Check if a user exit Usage is involved in the OLAP runtime?
c) Check if large hierarchies are used and the entry hierarchy level is as deep as possible. This limits the levels of the hierarchy that must be processed.
C)Strategy - High Frontend Runtime
1) Check if frontend PC are within the recommendation (RAM, CPU Mhz)
2) Check if the bandwidth for WAN connection is sufficient.
