I am currently dealing with a script which make some checks & insertions for each databases of a Mongo server. It’s multithreading.

for (int i = 0; i < countDatabase; i++) {     
    new threadDatabase(database.get(i).toString()).start();            
}

Problem : I have 16 databases to parse…I am afraid the PC where the script will be set up, won’t manage 16 (or more) threads…

Any ideas how to deal a large number of threads ? I heard about pool, but not sure it can deal with database name I send as parameter…

Thanks

    16 threads on a PC?

    Looking at my Windows Task manager/Performance, it shows 1238 threads running. It’s not even breaking a sweat. Top process is sidebar.exe – 66 threads.

    OK, so you’re running some other U**xy OS – 16 threads not likely to be a problem there either.

    16 threads is nothing. If they are all CPU-intensive, the box will get loaded up but, hey, that’s the point!

    Try a pool if you have to, maybe to try and improve performance, but don’t do it just because you are afraid that 16 threads is too much for your OS.
