multithreading - change the thread pool size of JVM -

-

i need change thread pool size of jvm . there possibility this. running high threaded jar on jvm. thats why threads goes under sleep or block stages.

the jvm doesn't have global thread pool per se. if using 1 of java.util.concurrent.executor-implementations, read on javadoc class/method. adjusted in java-code per pool have created (from code) , not related jvm.

that said, please consider each thread (typically) consumes 512k of virtual memory it's stack, limits number of maximum available threds 32-bit jvm (but doesn't sound problem @ all).

when threads block lot have kind of contention, meaning have common resource waiting for. perhaps you using "synchronized" lot? more threads won't solve problem, rather consume more resources in os , jvm.

please bit more details of code doing , how, , perhaps can bit more.

why need use because printers using tprinter prints weird hieroglyph @ beginning of printable area. my problem if send commands, nothing happens. esc e (#27 #69) - sending escape sequence didn't work expected. removed first letter , rest of string made bold. eg. hello -> ello . after changed esc e esc (#27 #69 #27), worked fine. example managed figure out, but... trying select character table "esc t n" (#27 #116 n), make "õäöü" work. command doesn't work. nothing happens! , command supported esc/p, esc/p 2 , 9-pin esc/p, should work fine. manual can found here . if has ever needed use esc/p commands maybe 1 can shed light how work them! thanks in advance! edit: in previous post asked more or less same question though answers how did send commands printer. (i'll change question there according answers!) i accepted ken's answer, because claimed way transferred commands wasn't best , got work escape command. problem after t...
