I want to make you and your peers more effective in delivery of value in software performance

@ryanlpeterman Ask the founder of a religion which religion is the path to truth.

Every language is an engineered product. There is a problem for which Haskall is the optimal solution. Nothing can beat it. Same holds for C (Rust, Python, Visual Basic, Java, ....)

OK... take my money

@Erva_00_1 This could have killed you. There are numerous other examples of this happening when an object is dropped from an overpass onto a windshield. Involve law enforcement

@Beno10_MFC This is a 3,4,5 right angle triangle

3^2+4^2=x^2
9+16=x^2
25=x^2
x=5

Slow software is a choice. 

Slow software increases your operational & support costs, reduces your employee productivity, increases your employee turnover, and leaves you rage-clicking your mouse at least once per month.

Choose to be fast.

@LUFC1992_v2 The difference in tornado watch vs warning, with tacos.

Software performance is not merely a technical concern—it is a source of revenue, operational, and cost risk.

For more than three decades, Perfacuity's principals have helped organizations identify, quantify, and mitigate those risks.

Performance engineering is an apprenticeship profession.

@Xklofrio @ClownWorld You would have to be (at least) a green card holder to legally possess a firearm. This would suggest that you are either (a) Legal Permanent Resident, (b) a Citizen, 0r (c) you are breaking gun laws. With (a) and (b) you have nothing to worry about. (c), you should worry.

@askanuragnow No, that is the power of poor developers who do not design for scale.

[James L. Pulley @perfpulley]

There are many technical reasons for these types of failure, but there are two structural ones
1. Monopolies build what is easiest for the monopoly and not for the consumer
2. Government agencies routinely ignore governance issues related to application performance

[James L. Pulley @perfpulley]

One of the common predictor patters for website faiure is a government monopoly website experiencing high load. COVID showed this to be a worldwide problem that continues to show up on every continent

@SMannfm11 @ttttttater @spencerpratt @soonerwings The aca website made a lot of assumptions about human behavior that were not true. Anyone who ever worked in eCommerce would have known. Also, no governance layer existed to own and manage performance on the project. This doomed the project from the outset to fail under load

[James L. Pulley @perfpulley]

@AliZeeshan01 Root cause, developers over allocated resources per session. Reducing your size, duration of hold, and frequency of request will reduce your origina server load per session, allowing for a higher load for your finite resource pool

@MatrixMysteries If you go to work for a government agency then your loan can be forgiven after ten years of on-time, full payments
