Re: [xSocket-develop] Question about optimization

Hi Gregor,

I will now use visual gc and provide more information ASAP. The problem 
appears even in the simple code where the only thing
I do is sending a query to MySQL database. I have tried to trigger GC by 
using System.GC but it didnt work (the chart was smoother,
but still it was going up). As I probably said before, using 
S_start - 
System.setProperty("org.xsocket.connection.server.readbuffer.usedirect", 
"true");C_start - 
System.setProperty("org.xsocket.connection.client.readbuffer.usedirect", 
"true");
helped me to get 50MB memory consumption (very high) in 60 minutes instead 
of 250MB in 20minutes without it.
Tried with flushing, but that didn't help at all. 
I will provide more info ASAP but could You, please, give me some hints as 
how to deal with GC/xsocket issues in general? Maybe 
this will help - in the same time Im working on visual gc info.
Best regards,
Michal

this reason the garbage collector should free memory after a period or time 
(by exceeding a threshold). Did you check the memory behaviour of your app 
with tools such as visual gc?

xsocket library so that the application works as server application, ie. the 
server doesnt increase in memory consumption. Memory and profiling
