Hi guys, Encouraged by recent Philippe's benchmarking I did similar on Aida with Swazoo web server, adding the comparison of Pharo with VisualWorks. Results are interesting, Pharo is now only 3x slower than VW on dynamic page generation but on network layer it is the same or even slighty faster, while it was around 10x slower on Squeak back in 2008 [1], Results (requests/s) -------------------- 1. Dynamically generated 3KB login page (/admin?view=login) VW: 120, Pharo: 40 ratio: 3x 2. Aida ping with zero size response (/ping.html) local: VW: 4700, Pharo: 4500 ratio: 1,04x lan: VW: 4500 Pharo: 4600 ratio: 0,97x inet: VW: 4000, Pharo: 3000 ratio: 1,33x 3. Aida ping with 8K response local: VW: 2600, Pharo: 3100 ratio: 0,84x lan: VW: 1400, Pharo: 1400 ratio: 1,00x inet: VW: 140, Pharo: 140 ratio: 1,00x Note: network saturation!
