Comment on Phusion Passenger for Python? by Felix

Ruby has Rack, Python has WSGI and Perl has PSGI. You should think in adding support for PSGI too. It would make Passenger the most complete solution for deploying webapps.

Comment on (Un)Support for prepared statements in Ruby on Rails by Sam Homer

The DB2 database adapter for Rails 3 supports prepared statements:
http://www.ibm.com/developerworks/data/library/techarticle/dm-1001db2rubyonrailsapps/

Now if only somebody could add this feature to the PostgreSQL adapter as well. To me the main reason to use prepared statements is not performance but security. In addition, the very nature of a rails app makes it a prime candidate for prepared statements: Rails basically fills templates with live data, and every template invocation calls the same queries, only with different parameters.

Comment on Saving memory in Ruby on Rails with fork() and copy-on-write by bandsxbands

Virtual Memory sure is becoming cheaper and cheaper and cheaper. I’m curious as to when we will eventually reach the ratio of 1c to 1 Gigabyte.I’m quietly waiting for the day when I will finally be able to afford a 20 TB hard disk, hahaha. But for now I guess I will be satisfied with having a 32 GB Micro SD Card in my R4i.(Submitted from FFBrows for R4i Nintendo DS.)

Comment on Non-antialiased fonts in gnome-terminal by Unholy Saint

Speaking of Gnome-Terminal, have you ever tried EvilVTE? It is if not the best, then at least both the fastest and most reasonable way to use VTE. Actually when/if they finally add scrollback search it will be the one and only terminal for me. It can be compiled to use bitmap font like Terminus with no antialiasing.

Fancy dress is porn? Or is embracing porn? I just do not get the problem.

i wonder from which source of irrationality does all this hypocrisy come from. death is bad, pain is bad, pictures of girls you want to make romance explosion on are NOT bad.

Comment on Benchmark: Passenger (mod_rails) vs Mongrel vs Thin by Robert. Tsai

Great work on the load test. I had a question about running passenger on vmware guest. Has any one seen the performance on a virtual machine yet? I’m just asking that beacuse we ran a load test with 200 concurrent connections against Thin on a Centos 5.4 VM and it failed. We are seeing high CPU usage per Thin. We tried setting running 5 Thins to 15 Thins and the load was very high compared to the app running natively. I want to see if anyone else is seeing the same performance degradation as we are seeing. I’m hoping Passenger would give us better performance.

Comment on Ruby vs PHP performance by Exit

Anyone run tests with compiled PHP (Zend encoded for instance)?

That also should be considered.
