I performed some differientials of the ST code along with runing the different versions/snapshots available for download from the suckless website on my Pentium3 (or i686) platform yesterday. The following is my experience of the performance of ST under this bug on i686. st-0.1* Slow character output to terminal, including key repeat. st-0.2* Character output to terminal was excellent. No delays were seen and key repeat worked as expected! st-0.3 Very Slow character output to terminal. st-0.4 Very Slow character output to terminal. st-0.4.1 Extremely Slow character output to terminal! Furthermore, adjusting the following line and the statically defined timeouts within the code to static values appeared to have zero or no effect at all: #define REDRAW_TIMEOUT (80*1000) /* 80 ms */ Now I did notice the drop from 80ms to 20ms delay within the st-0.2* versions, but changing this variable definition from 80ms to 20ms within the other versions had no effect. (Think I tested st-0.1*, st-0.3* and st-0.5*, changing 80ms to 20ms.) So, it looks like I'm moving forward with checking to see if the delay variables are actually using the expected delay using gdb (or printf), along with further comparing the changes between st-0.1*, st-0.2* and st-0.3. Whomever coded these early versions, might be able to very easily locate the slowdown explicitly at this point. -- Roger http://rogerx.freeshell.org/
