title: Thinking behind decision of database connection pool size
body: <p>i am working on opensource java based application i.e xwiki. Inside hibernate.cfg.xml i can see  value of parameters connection.pool_size and
  statement_cache.size as 2 (for each). My application will be having maximum load of 100 users at point of time. Now my question is what should be ideal connection pool size for this. To me  size 2 looks very less. If 100 users connect at a time 98 users have to wait for getting the connection released? Should i keep the connection pool size as 100 in my case?</p>
  <p>i am using microsoft sql server.</p>
  <p>Apart from this is there a limit on max connection pool size. Does it depend on webserver(tomcat in my case) or datastore vendor(ms sql server)?</p>
