It was the Bitcointalk forum that inspired us to create Bitcointalksearch.org - Bitcointalk is an excellent site that should be the default page for anybody dealing in cryptocurrency,
since it is a virtual gold-mine of data. However, our experience and user feedback led us create our site;
Bitcointalk's search is slow, and difficult to get the results you need, because you need to log in first to find anything useful - furthermore, there are rate limiters for their search functionality.
The aim of our project is to create a faster website that yields more results and faster without having to create an account and eliminate the need to log in -
your personal data, therefore, will never be in jeopardy since we are not asking for any of your data and you don't need to provide them to use our site with all of its capabilities.
We created this website with the sole purpose of users being able to search quickly and efficiently in the field of cryptocurrency
so they will have access to the latest and most accurate information and thereby assisting the crypto-community at large.
I get optimal performance when hyper threading is turned on and Bitcoin is limited to half the available cores. I get the same number of hashes per second when hyper threading is turned off, but hyper threading should allow better resource sharing between processes. Enabling Bitcoin to use all the virtual cores degrades the performance by roughly 7-8% and causes Firefox to lock up intermittently for a few seconds at a time. Enabling 6 or 7 out of 8 of my cores offers in between performance, but does not cause Firefox to lock up.
It seems that using 100% of half the virtual cores utilizes the full computing power of each core even though CPU performance graphs make it look like only half the computing power is being used. Using 100% of all the virtual cores also utilizes the full computing power of each core, but each virtual thread is then only utilizing on average 50% of the core and some performance is lost from the constant switching and balancing.
Thanks for including the hash measurement in version 0.3. In version 0.2 I almost always used more than half of my virtual cores.
P.S. My computer did not start up correctly when I restarted it and then disable hyper threading in the BIOS. I think it was because the computer needed to be powered down before making the change. I'm running Ubuntu AMD64 with an Intel Quad Core i7 at 2.8 GHz.
