  I have the same problem but with Apache and JServ. Someone responded
  that the buffering happens in the mod_jserv module of Apache. In fact 
  I found code in jserv_aip11,12.c which opens buffered sockets. In order
  to fix this both knowledge of the Apache API's and a MS - Windows C 
  compiler would be needed (I'am on NT, sorry). Where the latter might
  be the least problem. 

  I probably go for my own buffer and redisplaying a whole page anytime 
  I get new data until the lengthy operation is finished. BTW: I'am
  really annoyed about these differences between servlet engines.  
   

       I hope this helps and does not leave you to frustrated,
