I'm now performing basic benchmarking of the new version of Pari and it
seams to be much slower than the old one (i.e. 2.2.5). On the same
hardware (Pentium III 800Mhz with Linux 2.4.20) and with the same
compiler (gcc 2.95.4) Pari 2.2.6.alpha performance is somewhere around
  +++ Total bench for gp-sta is 1376
  +++ Total bench for gp-dyn is 1586

2.2.5, on the other hand, gives
  +++ Total bench for gp-sta is 1262
  +++ Total bench for gp-dyn is 1298

The difference is as much as %%10--20!

Is it something to be expected?
