24 Hours with an SSD and MySQL 13

I’ve now had about 24 hours to play with the Mtron SSDs and had some time to benchmark them. The good news is that the benchmarks look really solid. The drive is very competitive in terms of performance. I’m seeing about 100MB/s sequential read throughput and 80MB/s sequential write throughput. I’ve had some time to [...]

Thoughts on Maria and SSD 4

A lot of people have been buzzing about Maria over the last few days. One of the things I’ve been thinking about is how Maria/MyISAM fits into the SSD puzzle WRT InnoDB. InnoDB was generally designed for use with HDDs. Specifically, the write ahead log was added for MVCC and additional performance. However, MyISAM on [...]

Who can Test TSA Security? 0

CNN has an article about slipping fake bombs through TSA security: TAMPA, Florida (CNN) — Jason — that’s the name CNN was asked to call him — slides a simulated explosive into an elastic back support. The mock bomb is as slim as a wallet; its fuse, the size of a cigarette. He wraps the [...]

Crow Intelligence 0

I’m fascinated by intelligence in non-simian species. The Octopus and Crow are two animals that have vastly higher intelligence than a lay man would assume. I spent some time tonight doing research and found some interesting content on the subject. For example. This crow is smart enough to form a tool from wire in order [...]

Thoughts on SSD and MySQL 5.1 0

I’ve been reviewing our settings for innodb prior to testing our new SSDs drives later this week. Here are some initial thoughts: * Both sync_binlog and innodb_flush_log_at_trx_commit should both be enabled. The extra seeks required isn’t really an issue on SSD and the extra reliability is worth the slight performance hit. * Read ahead for [...]

Zeus IOPS – Another High Performance SSD 0

It looks like there’s another competitive SSD on the market. The Stec Zeus IOPS. I foolishly dismissed this drive before because I thought they weren’t disclosing their write rate (which all the other vendors are doing to lie about their performance). Turns out they’re claiming 200MB/s with 100MB/s write throughput. If these numbers are accurate [...]

Multiple String Pattern Matching 0

The Mailinator guys blogged about how they were using a modified Aho-Corasick style multiple string pattern matching algorithm to index 185 emails/s. Aho-Corasick takes all the search strings and builds them into a Trie so that it can scan the whole document for N strings in once pass. The problem is that Aho-Corasick doesn’t support [...]

Would you Pay $1 for a Feed 3

Center Networks things it might be a good idea to charge for feeds: What if blogs and journals offered a full feed for $1 per month with no ads, mobile access, etc. Would you subscribe for a buck? What I am proposing is the following forms of monetization: standard Web site with ads, partial feed [...]
