Hi prkr,
Can you check if e.g. a virus scanner is running in the background? To find more, you can use some monitoring tools.
Hi Andre,
Any specific monitoring tools are you talking about ?
FYI - we are facing so bad performance when utilization of CPU on SQL box is 2% and Memory consumption is around 20% and utilization of CPU & RAM on AOS box is also very low.
1) AxBuild is the fastest way to compile the entire application and the recommended way to do it. Compile time will be different depending on the performance of the system. In my experience it should take about 20 to 30 minutes to compile.
2) This is absolutely too long, in my experience, it should take between 5 to 15 minutes or so to start the AOS service. If it takes 3 to 4 hours, it seems your virtual servers are slow i.e. not getting enough processing time (I am no VM expert).
3) This is normal behaviour for opening forms the first time only after a build. The system caches the forms, and other elements, in a client cache. So the second time the form is opened, you should see an improvement.
Have a look at the disk speed on the SQL server, if your disks are slow AX will be slow.
Using Crystal Benchmark, our test server disk speed is around 800 Mb/s Read, 600 Mb/s Write
Also I would try to ping the SQL server from the AOS server just to make sure there is no delay there.
I would also say a full compile with axbuild should take no more than 20-30 mins.
I would check disk IOPs first and then check if resources are utilizing properly or not.
I have faced this issue recently where one of my cloud VM suddenly started performing slow (it was working fine earlier) and after 1-2 days it was back to normal.
I had opened up a ticket with support but they unable to provide me any RCA for it.
Check with support.
Just an update - we have now installed AOS on SQL box to test. It is performing a quite normal and take only 1-2 mins to AOS service restart. Things looks pretty normal now.
Problem is only on AOS communication with SQL when they are in different boxes. Your advises are welcomed in this regard. Thanks for your valuable comments by the way.
Is there any antivirus or firewalls security implemented between both server?
To dig into this performance issue, suggest to use process monitor and capture hang dumps to compare the call stack between dumps to see what is using most of time. Also need to check performance counters to see if any abnormal symptom.
