Hi. I'm creating a web-application using CherryPy 2.2.1. My application needs to process images (JPG/PNG files) to
1) create thumbnails (resize them) 2) overlay them on a custom background (a simple frame) 3) Overlay 'badges' (small 16x16 images) on top of the final thumbnail I am using PIL 1.1.5 which I have custom compiled on my development machine (MacBook Pro 2.33Ghz Core Duo).. I am using im.thumbnail for step 1 and im.paste for steps 2 and 3. The problem is that this thing is just way too slow. For ab -n 1000 -C session_id=2f55ae2dfefa896f67a80f73045aadfa4b4269f1 http://localhost:8080/imaging/icon/def/128/255 (where def is the name of the image - default in this case - 128 is the size in pixels and 255 is the background color), I am getting: Document Path: /imaging/icon/def/128/255 Document Length: 14417 bytes Concurrency Level: 1 Time taken for tests: 18.664 seconds Complete requests: 1000 Failed requests: 0 Broken pipe errors: 0 Total transferred: 14680000 bytes HTML transferred: 14417000 bytes Requests per second: 53.58 [#/sec] (mean) Time per request: 18.66 [ms] (mean) Time per request: 18.66 [ms] (mean, across all concurrent requests) Transfer rate: 786.54 [Kbytes/sec] received FYI: This request returns a PNG image (image/png) and not html My understanding is that the problem is either with the CherryPy setup (which is likely because even in other cases, i don't get much more than 65 requests per second) or PIL itself (even though I'm caching the background images and source images) Does anyone have a better solution? Is there a faster replacement for PIL? Thanks in advance. Prateek -- http://mail.python.org/mailman/listinfo/python-list
