• Speed improvements for Perl's chameneos-redux script in the Computer Language Benchmarks Game

  - by Robert P

  Ever looked at the Computer Language Benchmarks Game, (formerly known as the Great Language Shootout)? Perl has some pretty healthy competition there at the moment. It also occurs to me that there's probably some places that Perl's scores could be improved. The biggest one is in the chameneos-redux script right now - the Perl version runs the…

• Java bytecode compiler benchmarks

  - by Dave Jarvis

  Q.1. What free compiler produces the fastest executable Java bytecode? Q.2. What free virtual machine executes Java bytecode the fastest (on 64-bit multi-core CPUs)? Q.3. What other (currently active) compiler projects are missing from this list: http://www.ibm.com/developerworks/java/jdk/ http://gcc.gnu.org/java/…

• How accurate is apache benchmark?

  - by matthewsteiner

  Alright, so I'm in development right now and I'd like to understand exactly how good the benchmarks are. I've just been using apache benchmark. Do they include the server sending the files? Also, is "requests per second" literally how many users can visit the page within one second? If it's at 30 requests per second,…

• Linux compilers for C/C++ on AMD "Bulldozer" CPUs like the Interlagos [closed]

  - by jstarek

  I am looking for a Linux compiler for C/C++ code that supports AMDs new "Bulldozer" architecture and produces efficient binaries for the Interlagos series Opterons. This seems to be a bit difficult because of the peculiarities of the Bulldozer microarchitecture. While AMD has a whitepaper with some details, I would…

• Is an I/O benchmark made for hardware an accurate assessment of a Windows VM's performance under vSphere 5?

  - by Jeremy

  We support an enterprise application running on Windows Server 2008 R2. One of our customers has chosen to install to VMWare, and what I'm finding is that the VM's are relatively slow compared to hardware. Our product development team has advised that many VMs appear to run particularly slow on I/O benchmarks,…

• How much faster is a 64bit CPU than 32bit CPU? [closed]

  - by W.N.

  I just need the result in theory. I'm not an expert in computer architecture, just a software developer. Most of my friends think 64bit-CPU is 2 times faster than 32bit-CPU. But I think 64-CPU is 2 ^ 2 = 4 times faster than 32bit-CPU (in theory). Which is the right answer to this question? And, if there were…

• What benchmark tool to use to benchmark hardware for VM server?

  - by Mark0978

  We are setting up a new piece of hardware to virtualize several of our servers on. Choices are RAID 5, RAID 6, and RAID 0+1. We are wanting to benchmark all three before we go live with the machine, but I'm not sure how to test the speed. Since we will be using it to host VMs, what will the actual disk…

• There are lots of "Core i" CPUs, but Dell only offers a few -- who builds systems with the others?

  - by Jesse

  Passmark shows many varieties of Core i3, i5, and i7 cpus. Some of them, even at similar prices, are much faster than others. But Dell only offers a few options, and they're not the fast ones. For example, Dell offers the Core i5 650 (benchmark), which costs $220, and doesn't come close to the…

• Understanding this error: apr_socket_recv: Connection reset by peer (104)

  - by matthewsteiner

  So, if I do some benchmarking with apache benchmark (ab), and I use large numbers of requests. Then sometimes in the middle of a test I get this error. I don't even know what it means. So how can I fix it? Or is it just something that will happen if the server gets too many hits anyway? The…

• How do I know what hardware to buy to meet my needs?

  - by Darth Android

  While Stack Exchange does not permit shopping recommendations, it doesn't provide any general advice to consider when buying hardware. So, instead of just telling those that ask what to buy that it's not allowed, let's tell them how to figure out what they need. When looking…

• Is bigger capacity ram faster then smaller capacity ram for same clock and CL? [migrated]

  - by didibus

  I know that bigger capacity hard-drives with the same RPM are faster then smaller capacity hard-drives. I was wondering if the same is true for ram. Given two ram clocked at 1600mhz and with identical CLs: 9-9-9-24. Is a 2x8 going to perform better then a 2x4 ? Note…

• How to test server throughput

  - by embwbam

  I've always used apache benchmark to try to get a rough idea of how many requests/second my server can handle. I read that it was good, and it seemed to work well. Enter node.js, which is fully event-based, so it never blocks. If I run apache benchmark on a simple…

• CPU Benchmark - Set Load, usage spikes

  - by iulianchira

  I need a CPU benchmark to test the performance impact of various power management policies. I must be able to set the load (e.g. to get a relatively steady load of 20%-30%-60%) and to simulate usage spikes (set frequency of spikes). I would also like it to be…

  This question is quite general, but most specifically I'm interested in knowing if virtual machine running Ubuntu Enterprise Cloud (that's Xen-based) will be any slower than the same physical machine without any virtualization. How much (1%, 5%, 10%)? Did…
