It all started in 2004 when Amazon was running Oracle's enterprise edition with clustering and replication. Performant – DynamoDB consistently delivers single-digit millisecond latencies even as your traffic volume increases. We had an advanced team of database administrators and access to top experts within Oracle.

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

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. Happy content delivery!

SQL Server According to Bob

JANUARY 11, 2020

The caching of data pages and grouping of log records helps remove much, if not all, of the command latency associated with a write operation. In versions ​​ earlier than ​​ SQL Server 2004 SP4, SQL Server latch enforcement protection involved more protection transitions.
