Blackdown
Hey, Anyone know much about the garbage collector for the Blackdown JVM? I am talking about comparisons to Sun's, IBM's, etc. From recent experience it seems that the GC takes one big pause to collect the garbage where as other VM's do it a little more smoothly. Any thoughts? Sandy -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
Re: Blackdown
hm would have any idea of why I would be getting this very long garbage collection cycle. The same code running on a PC using JDK 1.1.7 does have the garbage collection cycle.

Re: GC... faster?
I am not to sure about Blackdown but I do that I IBM JVM for Linux. (1.1.7 is going to be available very soon, with 1.2 to follow close) has unbeleivable garbage collection. They do the GCing similar to HotSpot actually if I am not mistaken their GCing is better than HotSpot. So you even if it is not provided by Blackdown you will have an alternative.

Does anyone have the dates when Java 2 for Linux might be released from Sun? Sandy -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
Oracle's JDBC on Linux
Hey, I am running RH 5.2 with JDK117_v1a, and using the Oracle JDBC drivers for talking to the database. I have noticed that it takes between 4-5 secs to create a connection to the db. And when you have a connection pool with fair number of connection you can imagine howlong startup takes. Anyone else see this problem?
