In 2004 I was working for Microsoft in the Xbox group, and a new console was being created. Back in the day I wrote a lot of benchmarks in order to look for places where the actual performance of the CPU didn’t match what we expected. One benchmark I wrote measured the L2 cache latency. So, anyway. I wrote a lot of benchmarks.

Although both countries are relatively close to one another, they are separated by a distance of approximately 500km, which adds up in terms of latency. The use of online bank services, online shopping, and travel service browsing have increased significantly since spring 2004. In this case, the Helsinki POP’s identifier is fihe.

Breaking that assumption allowed Ceph to introduce a new storage backend called BlueStore with much better performance and predictability, and the ability to support the changing storage hardware landscape. 2004) was a user-space file system called the Extent and B-Tree based object file system. BlueStore performance highlights.

Screenshot: tracing read latency for PID 181: # bpftrace -e 'kprobe:vfs_read /pid == 30153/ { @start[tid] = nsecs; } kretprobe:vfs_read /@start[tid]/ { @ns = hist(nsecs - @start[tid]); delete(@start[tid]); }'. in 2004, so I have to think back to that time to understand it. It's shaping up to be a DTrace version 2.0: I wrote seeksize.d

It all started in 2004 when Amazon was running Oracle's enterprise edition with clustering and replication. We were pushing the limits of what was a leading commercial database at the time and were unable to sustain the availability, scalability and performance needs that our growing Amazon business demanded.

This query is performed by a Domain Name Server (DNS server) or servers nearby that have been assigned responsibility for that hostname. Using a fast DNS hosting provider ensures there is less latency between the DNS lookup and TTFB. They have been in operation since 2004 and have a long history of providing solid free DNS hosting.
