So now that I’ve finally got around to releasing a protocol built on top of the RpcLibrary I thought it would be fun to re-run some benchmarks. The protocol has been around unreleased for almost a year waiting on some required changes in protobuf-csharp-port which have finally been published in a release. The protocol I’m [...]
Let’s face it the clever guys at Google have more bandwidth than the rest of the nation combined. What better to do with all that excess pipe ;) There are of course numerous posts about the performances of +1 buttons. If you missed them there is the ever popular Google +1 Button Performance Review, and [...]
A few weeks ago I published NuGet packages for version 1.11.924.348. CSharpTest.Net.BPlusTree CSharpTest.Net.Library CSharpTest.Net.Logging CSharpTest.Net.RpcLibrary I also managed to get protobuf-csharp-port on board. I absolutely live by protobuffers. Google.ProtocolBuffers Google.ProtocolBuffersLite Finally I recently published a complete protobuf services rpc layer build on the RpcLibrary and protobuf-csharp-port. Of course much of the code there [...]
Recently I published a set of B+Tree benchmarks comparing a few of the available libraries against my own C# BPlusTree implementation. The author of RaptorDB wrote to me and requested that I review the latest version, 1.7 of RaptorDB. The points you made regarding RaptorDB were all valid in the previous version (pre the current [...]
Ok I swear this is the last B+Tree chart, graph, or metric I’ll post… at least for a while. I wanted to hit new limits so I fired up 6 threads on my six-core and let them rip… After three hours I finally stopped the run to look at the results. Each of the six [...]
Test Overview The benchmark results below are from a single thread on a process with the thread-affinity set except two. The BPlusTree(Threaded) and obviously MySql were not constrained. All data used during the test was generated before the test ran. The number displayed in the logarithmic horizontal axis is the average number of operations completed [...]
Before I go much farther talking about the BPlusTree I want to address one thing. Does the BPlusTree support ACID operations? (definitions below from wikipedia) Atomicity Atomicity requires that database modifications must follow an “all or nothing” rule. Each transaction is said to be atomic. If one part of the transaction fails, the entire transaction [...]
If you’ve missed it there is great article entitled Keep it secret, keep it safe by Eric Lippert. Essentially it attempts to dissect the essence of typical crypto issues in plain English (i.e. crypto for dummies). He did a great job of explaining the difficulties in key management, worth a read. I found it particularly [...]
Yes this site is still using wordpress, in fact, I’m writing this in wordpress right now. The interesting thing is I’ve completely uninstalled wordpress and MySql from my production server. I know crazy huh? So if I’ve peaked your curiosity you’ll want to stay tuned. Right now I don’t have time for a lot of details, [...]
A very minor update to the library this past weekend. Addition of Cyrpto.SecureTransfer to provide file transfers via shared public keys. The Crypto.AESCryptoKey now has ToArray() and FromBytes() like other keys. HashStream can now aggregate read/write calls to actual storage stream while computing the hash. The Crypto.Hash class received a new method, Combine(…) Html.XmlLightElement and [...]
