K... Iv'e just taken a look at both sets of java code. The reason it is not performing as well as C++ is the creation of objects, creating objects in java is SLOW. The trick is to instigate the objects you need at the start then REUSE the objects already created. Also on the threading use a pool. Failure to follow these two simple cases is why 90% of all java programs run slowly, because the bytecode is spending its time continually re-creating object it has just disposed of. Once memory gets squeezed, then the GC continually kicks in. OK I graphed it, you can clearly see the problem You can see the 'Heap' thrashing about as objects are created and destroyed

I have finally succeeded in putting together a (hopefully) working online miner for Litecoin. [...] http://www.litecoinpool.org/minerYou can use the username and password of one of your pool workers, or you can leave the "Worker" field blank if you just want to test it out (shares found this way are credited to a special pool account, and you will not be able to redeem them). [...] username and *password*? so my password has to be provided in plain text in the sources of my html file to use the online miner? So anyone reading the source code of my html file of my web server can login to my account at "litecoinpool.org" acc. to " http://www.litecoinpool.org/embed", I need to include <param name="auth" value="user.name:password"> in my web page in plain text. (sorry if I misunderstand sth - I am new to litecoin - glad if someone clarifies my misunderstanding, if any...)

That's the password of one of your workers, not your account password. All one can do with such a password is mine to your account. So anyone reading the source code of my html file of my web server can login to my account at "litecoinpool.org" No.

I guess it is clear once one starts *doing* all this oneself. But I for myself am just at the process of reading about all this on a yet theoretical level, so I was surprised reading about being supposed to publish a "password" in open space. Now I understand that in this case, what is called a "password" is actually just a sort of second "user ID" (in addition to the "user name"), because a "password" is typically something supposed to be kept secret, so the term "password" is misleading here, since this one is nothing that is meant to be kept secret.

Any idea when this pool will accept new users again?

I have finally succeeded in putting together a (hopefully) working online miner for Litecoin. This is still highly experimental, and of course this kind of miner will always be slower than the classic minerd. http://www.litecoinpool.org/minerYou can use the username and password of one of your pool workers, or you can leave the "Worker" field blank if you just want to test it out (shares found this way are credited to a special pool account, and you will not be able to redeem them). Please check it out, and let me know of any unexpected behavior! It would also be useful to have some feedback on hashrates for different machines. For instance, on the box I'm using for testing (a Core 2 Duo) this first version is about 3 times slower than ArtForz's cpuminer. I think that's quite a good Java-to-C ratio (I haven't finished optimizing the code yet), but of course your mileage may vary. UPDATE: On 64-bit systems, the current version can get up to 67% the speed of the reference miner by ArtForz (you must be running a 64-bit Java Virtual Machine and a 64-bit browser). 32-bit systems don't perform as well, but still manage to get about 50% of the speed. The source code is available under the GNU GPL license. https://github.com/pooler/JMinerHow can i use it with another pool website? like pool-x?

It is clearly stated on the website, but let me repeat it for the sake of clarity: this miner is to be considered deprecated, as it only supports the old getwork protocol. It is no longer officially supported at litecoinpool.org since August 27, 2013.

deprecated does not mean, not working...
afaict it should be working still. but i just don't see that it is on my site yet.
I've also signed up at the pool again, and have a miner on my pc directed to the pool itself.
You should definately support this, or re-direct to someone who is. for this pool, and this java web miner.
I'm still looking for a java web pool. I can setup the same way.
Thank you for produceing this.
