Some other expensive computation could be running during input generation. For example, if @st.composite or st.data() is interspersed with an expensive computation, HealthCheck.too_slow is likely to trigger. If this computation is unrelated to input generation, move it elsewhere. Otherwise, try making it more efficient, or disable this health check if that is not possible.72 > machine # [ 110.752185] h9w6ky85x5zxjfwnfzwpjk515bszby8n-concurrent-runner[752]: If you expect input generation to take this long, you can disable this health check with @settings(suppress_health_check=[HealthCheck.too_slow]).
