In TechChannel’s September 2026 survey of 10 IBM Power professionals, six said they had not experienced a significant performance bottleneck in the previous 12 months. The clearest pressure point was narrower: peak-volume document and label generation slowed for some respondents, most often because of data retrieval or communication with off-platform systems. TechChannel cautions that the small sample makes the results directional, not representative of the wider IBM Power market.
What the September TechPulse survey found
TechChannel published the recap on October 1, 2026, reporting responses from 10 IBM Power professionals. The counts below describe only those respondents; the report does not establish how they compare with IBM Power users as a whole.
| Survey area | Responses reported by TechChannel |
|---|---|
| Significant bottleneck in the prior 12 months | 6 of 10 reported none. Storage I/O was named by 2; network I/O and LPAR/virtualization configuration by 1 each. None named CPU/processor capacity or memory constraints as their most significant bottleneck. |
| Performance-history retention | 6 of 10 retained a multi-year baseline; 2 retained seven to 12 months; 1 retained one to six months; and 1 retained up to 30 days. Eight reported at least seven months of history, and none reported retaining no historical data. |
| IBM i optimization assessment | 7 of 10 rated their environments adequately optimized, while 3 were uncertain. No one selected highly optimized, under-optimized/over-provisioned, or constrained. |
| Peak document and label generation | 4 of 10 reported noticeable slowdowns at peak volume; 3 saw no noticeable impact; 1 had scaled hardware or added off-platform servers; and 2 did not monitor the workflow’s performance impact. No respondent said a significant bottleneck delayed shipping docks or customer delivery. |
| Causes of forms and labeling slowdowns | Among 9 who answered, 4 cited data retrieval, 3 cited communication latency between IBM i and external PC or Windows servers, and 2 cited outdated or inefficient generation software. None blamed printer or hardware limits. |
Where respondents reported performance pressure
The broad system-level responses and the workflow-specific answers point to different scales of concern. Most respondents did not report a significant bottleneck over the preceding year, but four did report noticeable effects during peak document and label generation, including temporary CPU spikes or drag on other application workloads. The survey therefore highlights a workload to examine, not evidence that document generation is a widespread IBM Power problem.
Among respondents who identified a significant bottleneck, storage I/O was the most frequently named category. The survey’s zero selections for CPU or memory constraints should not be read as evidence that those resources are unimportant in other environments; it describes only these 10 respondents’ answers.

What the answers suggest about diagnosis
Check data retrieval and off-platform communication
In the nine answers about forms and labeling slowdowns, data retrieval was cited most often, followed by latency involving IBM i and external PC or Windows servers. Generation software was cited by two respondents. These are reported attributions, not independently verified root-cause measurements, so they can help frame an investigation but cannot determine the cause in another organization.
Do not assume the printer is the constraint
No respondent in that question blamed printer or hardware limits. That finding does not rule out printer-side constraints elsewhere; it only shows that none of the nine respondents identified them in this survey.

Look at the workload during its peak window
A system-wide view can miss a short-lived workload effect. For teams handling high-volume document or label generation, it is useful to examine data access, cross-system exchanges, resource use, and neighboring application workloads during the actual peak period. The recap does not prescribe a particular monitoring product or prove that any one intervention will resolve a slowdown.
Performance history does not automatically answer whether a system is optimized
Eight of the 10 respondents said they retained at least seven months of performance history, including six with multi-year baselines. Yet three respondents were uncertain whether their IBM i environments were optimized; they cited insufficient tooling, metrics, or time to make that assessment. In other words, having historical data and being able to interpret it well enough to judge an environment are separate capabilities.

For capacity planning, retained history can provide context for changes over time, while an optimization judgment also depends on having suitable measures and the time and means to analyze them. The survey reports respondents’ retention and confidence levels; it does not establish a standard retention period or define an optimal IBM i configuration.
How far to take these results
TechChannel’s report says, “Due to the limited sample size, results are best read as directional.” It identifies 10 IBM Power professionals but does not describe the sampling frame, recruitment method, respondents’ roles, organization mix, or geography. It also provides no separately described survey instrument or independent validation. Accordingly, these figures should not be treated as a benchmark, market-wide prevalence estimate, or product comparison.
Rank #4
TechChannel also discloses, “This report was generated with AI assistance.” The recap contains no quotation attributed to a named person and cites no separate external statistics.
