High Memory,Disk and CPU usage on WSM Server

WSM 6.0.0 is changing the game as it is developed as true 64bit Application and hence don't have to cope with the memory limitation of 2GB for the OS Streaming Service. Still you should work to optimize your OS Image, but an upgrade on the Server Side (and of course the WSM Client in the OS Image) could get you some relief.
For customers with active maintenance the new version will be available in the Self Service Portal shortly.

Thank you for your reply

but i found the MaxSystemCacheMBytes configured to 32 i don't know it's 32G or what and i don't know what is the recommended for this register value and i can't understand this point

We found that some clients booting successfully and another takes extremely long time up to 20min until the logon screen appears,

and another day the users takes normal time,

i don't know what can i do ?!!

1-99 = limit the maximum size of the System File Cache to this percentage of currently available RAM. If it is set to 32 this is the percetage of RAM used and is for example 32% of 8GB = ~2,6GB
The default for 2-8GB of RAM is to use 75% of RAM if there is not MaxSystemCacheMBytes configured at all.
Have a look at SetCache.log file under “ \log” folder. This log file records the exact value system cache file size was set to.
Try to increase the value up to 70 which would result in a max System File Cache of ~5,6GB.
Monitor your network to find out if it is saturated with other traffic when WSM Clients boot slow.

Hi,

till now we can't solve the problem
and the users feels slow motion when the work

thx

WSM 5 Sizing and Planning Guide -> Search for MaxSystemCacheMBytes and read "Performance troubleshooting and OS Image optimization"

I would also suggest looking at the processes that are running at startup within the streamed image and stop any unneeded processes from running. Sysinternals AutoRuns is a good utility that can help with tracking down all the processes / services running at startup. Certain programs, like Windows Defender and anti-malware can cause an enormous amount of data to be transferred between the client and server

thank you for your reply

but there is any thing to do to solve this problem now ?

and is it a bug or what ?

thx

WSM 6.0.0 has just been posted

No, this is not a bug at all.
If your OS Image is not well optimized this can result in long boot times because the amount of data which is transfered between the client and server and also eat up server ressources quickly.
Please follow our suggestions above to find the root cause.

and what about wsm v 6 there is any article about it

thx

Hi,

I configured this suggestion and configured the MAX size to 50 and the boot is OK but all users feels slow motion when the work

thank you

Looking at the log file above, the "MaxSystemCacheMBytes reg value size = 4" and not 50 as you wrote in your post before.
1) Your Server has "Total Physical Memory: 8191 Mbytes, Available: 6763 Mbytes".
2) Because there are no settings in place how large the File System Cache can get, WSM sets this with the defaults: MaxSystemCacheMBytes: 80% of physical memory = 6553 Mbytes
If your system has "Available: 6763 Mbytes" and Cache can get 6553 Mbytes, there's little memory left for anything else, do you agree?
Check if your server is swapping a lot to page file and if yes, try to either add more memory or set MaxSystemCacheMBytes to 4000 for example, so it is only using 4000MB for caching.

and this is our log

is it OK ?

thank you for your help

what about wsm v 6 there is any article or anything about it ?!

thank you
