Log messages92tend to get added over time and this can lead to a throttling effect93on applications – such as reduced requests per second.94 95In many cases, Pino is over 5x faster than alternatives.96 97See the [Benchmarks](docs/benchmarks.md) document for comparisons.98 99### Bundling support100 101Pino supports being bundled using tools like webpack or esbuild. 102 103See [Bundling](docs/bundling.md) document for more information.104 105<a name="team"></a>106## The Team107 108### Matteo Collina109 110<https://github.com/mcollina>111 112<https://www.npmjs.com/~matteo.collina>113 114<https://twitter.com/matteocollina>115 116### David Mark Clements117 118<https://github.com/davidmarkclements>119 120<https://www.npmjs.com/~davidmarkclements>121 122<https://twitter.com/davidmarkclem>123 124### James Sumners125 126<https://github.com/jsumners>127 128<https://www.npmjs.com/~jsumners>129 130<https://twitter.com/jsumners79>131 132### Thomas Watson Steen133 134<https://github.com/watson>135 136<https://www.npmjs.com/~watson>137 138<https://twitter.com/wa7son>139 140## Contributing141 142Pino is an **OPEN Open Source Project**.
