Compare Latency. On average, ScaleGrid achieves almost 30% lower latency over DigitalOcean for the same deployment configurations. Now that we’ve compared throughput performance, let’s take a look at ScaleGrid vs. DigitalOcean latency for MySQL. Read-Intensive Latency Benchmark. Balanced Workload Latency Benchmark.

The innodb_io_capacity_max parameter was set to 2000, so the hardware should be able to deliver that many IOPS without major issues. ” Yes, this is true, io2 volumes are expensive, and honestly, I think they should be used only where really high IO capacity at expected latencies is required, and this didn’t seem to be the case.

The official documentation for sys.sysprocesses warns: This SQL Server 2000 system table is included as a view for backward compatibility. Recently one of our teams was investigating a log reader latency issue. We recommend that you use the current SQL Server system views instead.

For example, iostat(1), or a monitoring agent, may tell you your average disk latency, but not the distribution of this latency. For smaller environments, it can be of more use helping eliminate latency outliers. Kernel dynamic tracing of read() bytes bpftrace -e 'kretprobe:vfs_read { @bytes = lhist(retval, 0, 2000, 200) }'.

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. Back in 1984, FUNET was launched to connect Finnish universities and in 2000 internet in Finland was launched commercially. This is a massive increase from year 2000 when only 37.2%

This kind of approach is although a victim of latency and delayed execution. No matter what kind of cloud-based tool you are using, the latency is bound to happen since there are too many requests involved in between. This leaves the developer and tester with just selecting and analyzing the website on these browsers.

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]); }'. Back then I could already tell if disks were seeking by interpreting iostat(1) output: seeing high disk latency but small I/O.
