Re: [mapguide-users] mgcooker : use more cpu resource ?

[Lisa Weber]

Remy,

 

I have had similar experiences. I have tested the same tile cache process using 
MgCooker on two servers and a desktop and found it difficult to sustain a CPU 
usage above 27%. When I greatly increased the number of concurrent requests 
(over 10) that lifted the CPU to 34%, but a lot of tiles began to file, and the 
RAM usage maxxed out.

I found the only way to avoid failed tiles was to reduce the number of 
concurrent requests to 5 or less. This did not speed up the process 
significantly, as I generated the tiles a number of times using different 
numbers of concurrent requests.

The fastest configuration was the machine with the most RAM available which was 
the desktop, even with concurrent requests set to 1. The servers ran much 
slower, even though they were both multi-threaded.

 

 

 

Lisa

Thanks for your help.

 

I tried 

-  3 threading concurrent request, CPU increase to 75%.

 

But CPU vary between 8% and 41%

 

But after maybe 9 tiles, mgcooker failed to render tiles and I have this 
message  :

I tried 3 times  and same result.

-  2 threading concurrent request, CPU increase to 41%.

 

But CPU vary between 14% and 41%

 

Very strange too, total used memory display in task manager  increase very high 
(7.9 Go for 8Go) but when I check in resource monitor the memory addition 
process is not equal to the indication of task manager.

 

Mgserver.exe used only 360 Mo.

 

With resource monitor I see this :

o   Reserved material : 1 Mo

o   Used : 2236 Mo

o   Modified : 5000 Mo

o   Sleeped : 790 Mo

o   Free : 0 Mo

 

With Process Monitor (Procmon.exe) I see that for each tile mgserver.exe access 
to *.CS*.dll (il oose the name.

Is it normal ? it’s not a issue for performance.

 

Finally mgcooker failed to render tiles

 

On same time running, It seems that with one Thread mgcooker generate more 
tiles than with 2 or 3 trheads, because I think that with 2 or 3 treads there 
is  too much variation.

 

Thanks for ideas.

[Martin Morrison]

It is probably single threaded.  If so, one CPU is it.

Subject: [mapguide-users] mgcooker : use more cpu resource ?

Hi,

When mgcooker run, only 25% of CPU is using by mgserver.exe 2.5.2, I have 4 cpu.

If I set affinity cpu on only 1 core it’s  same thing 25%, but a little slower 
to generate tile.

To accelerate tile process, how can I increase this ?

-  Change serverconfig.ini ?

-  Duplicate mapagent ?

-  Else ?

Thanks for your help

Re: [mapguide-users] mgcooker : use more cpu resource ?

[Jackie Ng]

There's a thread count setting in the MgCooker UI (that should also be saved
if you're generating an executable script). Does that not multi-thread the
tile generation process?
