I recently bought a new 2TB SSD to handle my virtual machines. This one is m.2, was previously using 256 GB SATA drive. Nothing against SATA, it just can't compete on speed with m.2.

Windows 7 x64 Performance - Host and Guest
· β˜• 1 min read
I am running Windows 7 x64 both as a host and a guest VM using VMWare Workstation v9. Here are the figures of Windows Experience Index for each instance, so you can estimate virtualization efficiency: Host Windows 7: Guest Windows 7 - VMWare Workstation v.9: Guest VM is allocated 2 cores, out of 4 cores total on my Intel i7-4770. As you probably have heard, Windows 7 uses logarithmic scale for its performance score.

Dual HexaCore Xeon E5649 performance in HP DL380 G7

First benchmarked using latest Passmark. Then did some tests with latest Aida64. What's interesting here is that both processor and memory speed keeps fluctuating. I have not found a good explanation for this behavior.

Here are the results from CrystalDiskMark 3.0.1 (x64), connected over USB2.0 and USB3.0 respectively. Very diligent with specs, and actually performing better at USB2 than advertised by ADATA. Looks like a good deal for 30$.

.NET parallel for - how good is it?
· β˜• 2 min read
I recently had a Microsoft workshop session and became excited about parallel for/foreach/etc. There we got a solid 60% of efficiency. It means that whenever number of cores increases by 2x, performance is boosted by 1.6x.

Intel X25-M 80GB (SSDSA2M080G2GC) - usage report
· β˜• 1 min read
I ordered mine on 12-Apr-2010, and it’s December now, so it’s ~6 months of light use, 135 days = 4.5 months of uptime and an average 6GB of writes per actual day, which translates in just a bit over 1TB of writes. The drive already has 1 bad sector, which was remapped about a month ago. Decided to test performance with AS SSD Benchmark, and here’s the screenshot with results.

Intel X25-M SSD in HP Proliant DL380 G5
· β˜• 3 min read
Hardware - HP Proliant DL380 G5, two disks, one is Intel SSD and another one is HP SCSI 15K drive, each running as RAID0. Software - IOMeter, latest version. File system - default NTFS partitions were setup, with Intel being a system drive. It might sound like a bit of overhead (bringing incorrect measurements), but honestly, I don't think it would really matter on such speeds and IOps. Controller caching - 25% read/75% write.
