Performance Degradation from SSL

I have read articles which are showing that performance could go down to
1/10 with certain servers (Reference
http://isglabs.rainbow.com/isglabs/shperformance/SHPerformance.html) when
using SSL.
I am cuurently using WebLogic 4.5. Can anybody tell me what kind of
performance degradation would I see if I switch all my transactions from
normal unsecure http transactions to secure ones (SSL V3)?
Any help appreciated.
best regards, Andreas

Andreas,
Internal benchmarks (unofficial) have shown SSL to be 65-80% slower than
typical connections. So, anywhere between 3 to 5 times slower. This is the
same across all http servers.
In Denali (the next release), we're adding a performance pack enhancement
that includes native code impls of some of our crypto code. This should
show large speedups when it's released in March.
Thanks!

Performance degradation after setting filesystemio_option=setall from none.

Hi All,
We have facing performance degradation after setting filesystemio_option=setall from none on my two servers as mentioned below.
Red Hat Enterprise Linux AS release 4 (Nahant Update 7) 2.6.9 55.ELhugemem (32-bit)
Red Hat Enterprise Linux Server release 5.2 (Tikanga) 2.6.18 92.1.10.el5 (64-bit)
We are seeing lots of Disk I/O happening. We expected "*filesystemio_option=setall* " will improve performance but it is degrading. We getting slowness complains.
Please let me know do we need to set somethign else along with this ...like any otimizer parameter( e.g. optimizer_index_cost_adj, optimizer_index_caching).
Please help.

Hi Suraj,
<speculation>
You switched filesystemio_options to setall from none, so, the most likely reason for performance degradation after switching to setall is the implementation of directio. Direct I/O will skip the filesystem buffer cache, and and allow Oracle to read directly from disk to the database buffer cache. However, on a system where direct I/O is not implemented, which is what you had until you recently messed with that parameter, it's likely that you had an undersized database buffer cache, but that was ok, because many (most) of the physical I/Os your database was doing, were actually being serviced by the O/S filesystem buffer cache. But, you introduced direct I/O, and wiped out the ability of the O/S to service any physical I/Os from filesystem buffer cache. This means that every cache miss on the database buffer cache, turns into a real, physical, spin-the-disk, move-the-drive-head, physical I/O. And, you are suffering the performance consequences.
</speculation>
Ok, end of speculation. Now, assuming that what I've outlined above is actually going on, what to do? Why is direct I/O lower performing than buffered, non-direct I/O? Shouldn't it's performance be superior?
Well, when you have an established system that's using buffered I/O, and you switch to direct I/O, you almost always will have to increase the size of the database buffer cache. The problem is that you took a huge chunk of memory away from the the O/S, that it was using to buffer your I/Os and avoid physical I/O. So, now, you need to make up for it, by increasing the size of the database buffer cache. You can do this, without buying more memory for the box, because the O/S is no longer going to need to use so much memory for filesystem buffers.
So, what to do? Is it worth switching? Well, on balance, it makes sense to use direct I/O, and give Oracle a larger database buffer cache, for the simple fact that (particularly on a server that's dedicated to being an Oracle database server), Oracle has far more sophisticated caching algorithms, and a better understanding of the various types of data being cached, and so should be able to make more efficient use of the memory, than the (relatively) brain dead caching algorithms of the kernel and filesystem mechanisms.
But, once again, it all comes down to this:
What problem are you trying to solve? Did you have any I/O related issues? Do you have any compelling reason to implement direct I/O? Rule #1 is "if it ain't broke, don't fix it." Did you just violate rule #1? :-)
Finally, since you're on Linux, you can use the 'free' command to see how much memory is on the box, how much is free, and how much is dedicated to filesystem cache buffers. This response is already pretty long, so, I'm not going to get into details, however, if you're not familiar with the command, the results could be misleading. Read the man page, and try to be clear about understanding it before you make any assumptions about the output.
Hope that helps,

Performance degradation with addition of unicasting option

We have been using the multi-casting protocol for setting up the data grid between the application nodes with the vm arguments as
*-Dtangosol.coherence.clusteraddress=${Broadcast Address} -Dtangosol.coherence.clusterport=${Broadcast port}*
As the certain node in the application was expected in a different sub net and multi-casting was not feasible, we opted for well known addressing with following additional VM arguments setup in the server nodes(all in the same subnet)
*-Dtangosol.coherence.machine=${server_name} -Dtangosol.coherence.wka=${server_ip} -Dtangosol.coherence.localport=${server_port}*
and the following in the remote client node that point to one of the server node like this
*-Dtangosol.coherence.wka=${server_ip} -Dtangosol.coherence.wka.port=${server_port}*
But this deteriorated the performance drastically both in pushing data into the cache and getting events via map listener.
From the coherence logging statements it doesn't seems that multi-casting is getting used atleast with in the server nodes(which are in the same subnet).
Is it feasible to have both uni-casting and multi-casting to coexist? How to verify if it is setup already?
Is performance degradation in well-known addressing is a limitation and expected?

Hi Mahesh,
From your description it sounds as if you've configured each node with a wka list just including it self. This would result in N rather then 1 clusters. Your client would then be serviced by the resources of just a single cache server rather then an entire cluster. If this is the case you will see that all nodes are identified as member 1. To setup wka I would suggest using the override file rather then system properties, and place perhaps 10% of your nodes on that list. Then use this exact same file for all nodes. If I've misinyerpreted your configuration please provide additional details.
Thanks,
Mark

Performance Degradation with EJBs

I have a small J2EE application that consists of a Session EJB calling 3 Entity EJBs that access the database. It is a simple Order capture application. The 3 Entity beans are called Orders, OrderItems and Inventory.
A transaction consists of inserting a record into the order table, inserting 5 records into the orderitems table and updating the quantity field in the inventory table for each order item in an order. With this transaction I observe performance degradation as the transactions per second decreases dramatically within 5 minutes of running.
When I modify the transaction to insert a single record into the orderitems table I do not observe performance degradation. The only difference in this transaction is we go through the for loop 1 time as opposed to 5 times. The code is exactly the same as in the previous case with 5 items per order.
Therefore I believe the problem is a performance degradation on Entity EJBs that
get invoked in a loop.
I am using OC4J 10.1.3.3.
I am using CMP (Container Managed Persistence) and CMT (Container Managed Transactions). The Entity EJBs were all generated by Oracle JDeveloper.
EJB version being used is 2.1.

One thing to consider it downloading and using the Oracle AD4J utility to see if it can help you identify any possible bottlenecks, on the application server or the database.
AD4J can be used to monitor/profile/trace applications in real time with no instrumentation required on the application. Just install it into the container and go. It can even trace a request from the app server down into the database and show you the situation is down there (it needs a db agent installed to do that).

Performance Degradation - High fetches and Prses

Hello,
My analysis on a particular job trace file drew my attention towards:
1) High rate of Parses instead of Bind variables usage.
2) High fetches and poor number/ low number of rows being processed
Please let me kno as to how the performance degradation can be minimised, Perhaps the high number of SQL* Net Client wait events may be due to multiple fetches and transactions with the client.

But if you look at the text you are using bind variables.
The first query is executed 239 times - which matches the 239 fetches. You cut off some of the useful information from the tkprof output, but the figures show that you're executing more than once per parse call. The time is CPU time spent using a bad execution plan to find no data -- this looks like a bad choice of index, possibly a side effect of the first_rows(1) hint.
2) High fetches and poor number/ low number of rows being processedThe second query is doing a lot of fetches because in 163 executions it is fetching 4.7 million rows at roughly 25 rows per fetch. You might improve performance a little by increasing the array fetch size - but probably not by more than a factor of 2.
You'll notice that even though you record 163 parse calls for the second statement the number of " Misses in library cache during parse" is zero - so the parse calls are pretty irrelevant, the cursor is being re-used.

Performance degradation of Weblogic 5.1 sp 6 bundled with Peoplesoft 8.1.2:

Recenly we have upgraded from Peoplesoft 7 to Peoplesoft 8.1.2
Peoplesoft 8.1.2 bundled with Peopletools(Web based front end ) for the first
time and Weblogic 5.1 sp6.
There is performance degradation of the weblogic 5.1 sp 6 (on Windows 2000 ) when
the no of users increases to 80. The Weblogic is becoming 100% CPU bound. Besides
the weblogic wont even shutdown completely when trying to shutdown.
Peoplesoft customer support advised to upgrade to Weblogic 5.1 sp 9 but sp 9 wont

There shouldn't be any reason that 5.1 SP9 wouldn't support 128 bit
encryption. If that's the issue, you should post in the security
newsgroup or contact [email protected]

Performance degradation encountered while running BOE in clustered set up

Problem Statement:
We have a clustered BOE set up in Production with 2 CMS servers (named boe01 and boe02) . Mantenix application (Standard J2EE application in a clustered set up) points to these BOE services hosted on virtual machines to generate reports. As soon as BOE services on both boe01 and boe02 are up and running , performance degradation is observed i.e (response times varies from 7sec to 30sec) .
The same set up works fine when BOE services on boe02 is turned off i.e only boe01 is up and running.No drastic variation is noticed.
BOE Details : SAP BusinessObjects environment XIR2 SP3 running on Windows 2003 Servers.(Virtual machines)
Possible Problem Areas as per our analysis
1) Node 2 Virtual Machine Issue:
This currently being part of the Production infrastructure, any problem assessment testing is not possible.
2) BOE Configuration Issue
Comparison report to check the build between BOE 01 and BOE 02 - Support team has confirmed no major installation differences apart from a minor Operating System setting difference.Question being is there some configuration/setting that we are missing ?
3) Possible BOE Cluster Issue:
Tests in staging environment ( with a similar clustered BOE setup ) have proved inconclusive.
We require your help in
- Root cause Analysis for this problem.
- Any troubleshooting action henceforth.
Another observation from our Weblogic support engineers for the above set up which may or may not be related to the problem is mentioned below.
When the services on BOE_2 are shutdown and we try to fetch a particular report from BOE_1 (Which is running), the following WARNING/ERROR comes up:-

We see the above warning coming 2 or 3 times before the request is processed and then we see the report. We have checked our config's for the cluster but didn't find anything concrete.
Is this a normal behavior of the software or can we optimize it?
Any assistance that you can provide would be great

Rahul,
I have exactly the same problem running BO 3.1 SP3 in a 2 machine cluster on AIX. Exact same full install on both machines. When I take down one of the machines the performance is much better.
An example of the problem now is that when i run the command ./ccm.sh -display -username administrator -password xxx on the either box when they are both up and running, I sometimes receive a timeout error (over 15mins)
If I run SQLplus direct on the boxes to the CMS DB then the response is instant. Tnspings of course shows no problems
When I bring down one of the machines and run the command ./ccm.sh -display again then this brings back results in less than a minute...
I am baffled as to the problem so was wondering if you found anything from your end
Cheers
Chris

Performance degradation. Need advice on starting all over again.

I have never formatted my drive or reinstalled my OS X like I used to do with XP during the windows days. Now there is some performance degradation and opening of applications like Safari, iPhoto and others is really slow. I maintain Time Machine backups of my full Snow Leopard partition. What should I do? Format the HD, re install SL, or simply restore from TM or reinstall and then restore...?
I dont really want to carry my windows attitude to mac, of reformatting, reinstalling and then starting all apps from scratch. I wanna leverage out of my TM backup. Please advice.

Those steps, repair permissions? only checks the installed application receipts -- worthless.
Disk Utility doesn't check for bad blocks, and Apple First Aid misses and doesn't fix directory problems that are picked up by 3rd party tools like Disk Warrior.
The hatter's comments do not represent a consensus of opinion about this & are at least partially misleading.
Permissions repairs are indeed limited to comparing receipt info to actual permissions settings, but that is hardly worthless. It is well documented that mis-set permissions will cause a number of problems & resetting them to receipts values is an effective cure for those specific problems. Obviously, that won't cure problems with other causes, but since there is no magic cure-all it would be foolish to expect it to behave like one.
Regarding Disk Utility, it is true that it can't repair certain problems that some 3rd party utilities can; however, it is very effective at identifying file system problems, including those for some file systems the 3rd party apps do not support. It is also the most conservative disk utility available, designed not to attempt any repair that could result in loss of data. This is one reason it isn't as powerful as the 3rd party ones -- it is best to use it first if you suspect you have file system problems & use the more powerful ones only when necessary.
To be fair, Disk Warrior includes a directory optimization function that Disk Utility doesn't. However, an "unoptimized" directory isn't a problem in & of itself, & it is debatable how much real world benefit there is to optimizing the directory, at least with the current OS & modern high performance drives. I used to see noticeable improvements by periodically using Disk Warrior with OS 9 & the drives of that era, but these days my Macs & Snow Leopard seem to do just fine without it.
Basically, it is simple: use the tool that best does what you need to do. There is no benefit from using a sledge hammer when a tack hammer will do; in fact, the sledge hammer may do more harm than good, or just wear you out for no good reason. Also consider the wisdom of the old saying that to a hammer everything looks like a nail. Sometimes, you don't need a tool at all, just the wisdom to know that you don't.
Regarding bad sectors, every drive has them. That is not a concern by itself but the drive suddenly developing new ones is a sure sign of serious problems. Drives keep track of this themselves. Utilities provide a way to query the drives about this & may provide early warning of impending failure, but since the drive is providing the info this is not 100% reliable. For this reason, whether you use one or not, it is extremely important to backup your important data to other devices regularly & often.

Performance degradation using Jolt ASP Connectivity for TUXEDO

We have a customer that uses Jolt ASP Connectivity for TUXEDO and is suffering
from a severe performance degradation over time.
Initial response times are fine (1 s.), but they tend to increase to 3 minutes
after some time (well, eh, a day or so).
Data:
- TUXEDO 7.1
- Jolt 1.2.1
- Relatively recent rolling patch installed (so no there are probably no JSH performance
issues and memory leaks as fixed in earlier patches)
The ULOG shows that during the night the JSH instances notice a timeout on behalf
of the client connection and do a forced shutdown of the client:
040911.csu013.cs.kadaster.nl!JSH.234333.1.-2: JOLT_CAT:1185: "INFO: Userid:
[ZZ_Webpol], Clientid: [AP_WEBSRV3] timed out due to inactivity"
040911.csu013.cs.kadaster.nl!JSH.234333.1.-2: JOLT_CAT:1198: "WARN: Forced
shutdown of client; user name 'ZZ_Webpol'; client name 'AP_WEBSRV3'"
This happens every 10 minutes as per configuration of the JSL (-T flag).
The customer "solved" the problem for the time being by increasing the connection
pool size on the IIS web server.
However, they didn't find a "smoking gun" - no definite cause for the problem.
So, it is debatable whether their "solution" suffices.
It is my suspicion the problem might be located in the Jolt ASP classes running
on the IIS.
Maybe the connection pool somehow loses connections over time, causing subsequent
users having to queue before they get served (although an exception should be
raised if no connections are available).
However, there's no documentation on the functioning of the connection pool for
Jolt ASP.
My questions:
1) What's the algorithm used for managing connections with Jolt ASP for TUXEDO?
2) If connections are terminated by a JSH, will a new connection be established
from the web server automatically? (this is especially interesting, because the
connection policy can be configured in the JSL CLOPT, but there's no info on how
this should be handled/configured by Jolt ASP connectivity for TUXEDO)

Winfried Scheulderman

Hi,
For ASP connectivity I would suggest looking at the .Net client facility provided in Tuxedo 9.1 and later.

Performance degradation of Weblogic 5.1 sp 6 when used with Peoplesoft 8

Recenly we have upgraded from Peoplesoft 7 to Peoplesoft 8.
There is performance degradation of the weblogic 5.1 sp 6 (on Windows 2000 ) when
the no of users increases to 2000. Besides the weblogic wont even shutdown completely
when trying to shutdown.
Weblogic customer support advised to upgrade to sp 8 but sp 8 wont support 128
bit encription which peoplesoft 8 need.
Any of you had such an experience ? Please let me know if there is a solution
or workaround.
Thanks in advance.

Performance degradation in pl/sql parsing

We are trying to use xml pl/sql parser and noticed performance degradation as we run multiple times. We zeroed into the following clause:
doc := xmlparser.getDocument(p);
The first time the procedure is run the elapsed time at sqlplus is something like .45sec, but as we run repeatedly in the same session the elapsed time keeps on increasing by .02 seconds. If we log out and start fresh, we start again from .45sec.
We noticed similar degradation with
p := xmlparser.newParser;
but we got around by making the 'p' variable as package variable, initializing it once and using the same for all invocations.
Any suggestions?
Thank you.

Can I enhance the PL/SQL code for better performance ? Probably you can enhance it.
or, is this OK to take so long to process these many rows? It should take a few minutes, not several hours.
But please provide some more details like your database version etc.
I suggest to TRACE the session that executes the PL/SQL code, with WAIT events, so you'll see where and on what time is spent, you'll identify your 'problem statements very quickly' (after you or your DBA have TKPROF'ed the trace file).
SQL> alter session set events '10046 trace name context forever, level 12';
SQL> execute your PL/SQL code here
SQL> exitWill give you a .trc file in your udump directory on the server.

Performance Degradation of new Servers

Hi All,
We are experiencing massive performance degradation on production when the system is under heavy use. It seems to be at its worst around month end. The worst effected transactions are the Cost / Profit centre 'line item' reports using RCOPCA02 (and other similar programs).
We have the message server running on the database instance as well as 2x App servers. The Msg Srv and One of the App servers are very similar builds
4x AMD Opteron 875
16gb RAM (10gb Pagefile)
Both running Win Server 2003
We're using MS SQL 2000
The other message server is a bit weaker but has been around for some time (few years) and hasn't caused any issues.
We have recently moved the Msg Server from an old (much weaker) server to the new build and since then seem to have performance issues. Initially after the move we had issues with the number of Page Table Entries (where down at about 6000-8000). Using the /3GB /USERVA=2900 switches we have this up to about 49,000.
If anyone has had a similar experience or could offer some assistance it would be much appreciated!!!
Cheers,
Kye

While investigating a different issue we've found that we have 3 servers that share the same set of disks on the SAN. Two of these where Message Servers (R/3 and BW) when both of these where running the 'Average disk queue Length' was at times reaching 400! (should be around 1-3).
We've moved one of these instances back to DR which has relieved some of the pressure from the disks.
We have also added another index to the GLPCA table (which was causing most of the problems).

Performance degradation after upgrading to yosemite

I'm experiencing performance degradation on MacBook Pro 15 including
number of spinning wheels,
instance of dark screen,
overheating after upgrading to Yosemite
diminished battery life
Is Yosemite the cause of this and other issues

I can't believe Apple have made this software available to the masses when it's clearly not ready. Since "upgrading" my Mac mini has been pretty useless. Programs take a substantially increased time to open compared to Mavericks, and then performance is poor at best. Opening files in Photoshop, for example, is painfully slow and I get the colour wheel almost all of the time - something which definitely didn't happen with Mavericks.
Aside from this, I've experienced a number of frustrating bugs today. When I open a new program on my left screen the right screen is changed to a fresh desktop. Why? When I turn my Mac on I get the login screen on the left monitor (as it always used to) but then the primary desktop is set to the right and I've been unable to keep the correct setting so far (it forgets that I've changed it following a reboot). The background of the top bar keeps disappearing so all of the icons, time, etc. just sit on top of the desktop background.
I hope Apple can release a fix, and quickly.

Please help me figure out why this thread's performance degrades over time

Hello.
The code below is from a Runnable that I've tested inside a Thread operating on a TreePath array of size 1500; the array 'clonedArrayB' is this TreePath array. The code is designed to create a more stepped version of setSelectionPaths(TreePath[]) from class JTree.
The performance decrease of the thread is very rapid; this is discernible simply from viewing the println speed. When it gets to about 1400 TreePaths added to the JTree selection, it's running at roughly 1/10 the speed it started running at.
I know there's no problem with maintaining a set of selected paths of that size inside a JTree. I also know that the thread stops when it should. So it must be some operation I'm performing inside the brief piece of code shown below that is causing the performance degradation.
Does anyone have any idea what could be causing the slowdown?
Many thanks for your help. Apologies if you would have liked an SSCCE, but I very much doubt it's necessary for this. Either you can see the problem or you can't. And sadly I can't x:'o(
int indexA = 0;
public void run() {
     // Prevent use of / Pause scanner
     try {
          scannerLock.acquire();
     } catch (InterruptedException exc) {
          Gecko.logException("Scanner lock could not be acquired by expansion thread", exc);
     while (!autoExpansionComplete) {
          while (indexA < clonedArrayA.length) {
               int markerA = indexA + 10;
               for (int a = indexA; a < markerA && a < clonedArrayA.length; a++) {
                    pluginTreeA.addSelectionPath(clonedArrayA[a]);
               indexA = markerA;
               System.out.println(indexA + "," + clonedArrayA.length);
                    if (autoExpansionComplete) {
                         break;
               stop();
};

Well, since I've had no responses, I tried to think of other ways to speed the code up.
I'd already made nearly every tweak I know. The only additional thing I could think of was to use addSelectionPaths(TreePath[]) on a subarray of the cloned array, instead of addSelectionPath(TreePath) on the cloned array's elements, since obviously it would be fewer method calls. It has sped things up an awful lot (my new code is shown below - I've left in some things I chopped out above, so you can see exactly what I see). The problem is though, obviously an increase in initial velocity doesn't solve the problem of deceleration occurring, if you get me.
// Clone the selection arrays to non-volatile arrays for better access
// speeds
final TreePath[] clonedArrayA = selectionPathsArrayA.clone();
final TreePath[] clonedArrayB = selectionPathsArrayB.clone();
// Create a new runnable to perform the selection task
Runnable selectionExpander = new Runnable() {
     /** Position within cloned array A */
     int indexA = 0;
     /** Position within cloned array B */
     int indexB = 0;
     /** Length of subarray grabbed from cloned array A */
     int lengthA;
     /** Length of subarray grabbed from cloned array B */
     int lengthB;
     /** Subarray destination */
     private TreePath[] subarray = new TreePath[100];
     public void stop() {
          autoExpansionComplete = true;
          automatedSelection = false;
          scannerLock.release();
      * Grabs 10 blocks of each selection paths array at a time, adding
      * these to the tree's current selection and then moving to the next
      * cycle
     public void run() {
          // Prevent use of / Pause scanner
          try {
               scannerLock.acquire();
          } catch (InterruptedException exc) {
               Gecko.logException("Scanner lock could not be acquired by expansion thread", exc);
          while (!autoExpansionComplete) {
               while (indexA < clonedArrayA.length || indexB < clonedArrayB.length) {
                    // Set subarray lengths
                    lengthA = subarray.length;
                    lengthB = subarray.length;
                    // If subarray length is greater than the number of
                    // remaining indices in the source array, set length to
                    // the number of remaining indices
                    lengthA = indexA + lengthA > clonedArrayA.length ? clonedArrayA.length - indexA : lengthA;
                    lengthB = indexB + lengthB > clonedArrayB.length ? clonedArrayB.length - indexB : lengthB;
                    // Create subarrays and add TreePath elements to trees'
                    // selections
                    System.arraycopy(clonedArrayA, indexA, subarray, 0, lengthA);
                    pluginTreeA.addSelectionPaths(subarray);
                    System.arraycopy(clonedArrayB, indexB, subarray, 0, lengthB);
                    pluginTreeB.addSelectionPaths(subarray);
                    // Remember the latest index reached in source arrays
                    indexA += lengthA;
                    indexB += lengthB;
                    System.out.println(indexA + "," + clonedArrayA.length);
                    System.out.println(indexB + "," + clonedArrayB.length);
                    if (autoExpansionComplete) {
                         break;
               stop();
// Create and start new thread to manage the selection task runner
selector = new Thread(selectionExpander);
selector.start();I really can't think what could be causing the slowdown. I've done everythng I can think of to increase the velocity, such as cloning the source arrays since they're volatile and access could be slightly slower as a result.
Nothing I try gets rid of the slowdown effect though :(
